Laser pointer on Wheel balancer

Recommended Posts

I have an older coats wheel balancer. Works great and is accurate. The problem is that on modern car 19-22" wheels it becomes really hard to eyeball the correct place on the wheel for the weight. Extra spins become common because the last weight was a few degrees off the mark. Newer balancers have laser pointers that make it easy. Has anyone retrofitted a pointer to their older balancer? Did you buy a kit or did you build something? I've done some searching but I can't find anyone that's done this before. I feel like it would be really handy.

    • Article: Identifying the Problem with Your Shop

      I have never met a shop owner who didn’t have the desire to be successful. People go into business with dreams of changing the world and to make a positive influence in the industry to which they have dedicated their lives. They’re devoted, sacrifice time away from family and, at times, drive themselves to exhaustion—all in an effort to become the best they can be and make their mark. However, all too often, something happens along the way and the business begins to suffer. While shops owners may start their business with passion and vision, they tend to create a world in which everything revolves around them. When the business is small, the owner pays careful attention to every detail. Every car is repaired with the highest degree of excellence. Quality time is spent with each customer and a bond is created, which gets stronger and stronger as the years pass. As the business begins to grow, the owner realizes that the amount of work to be accomplished each day is overwhelming and hires more employees. Everyone is working, but not necessarily with the same culture the owner has. They do their job, but they are not really aligned with the goals and vision of the owner. The shop owner continues to work on his or her skills, learning everything that is needed to run a successful business. After a number of years, the shop owner becomes skilled at running a shop and proficient in nearly every aspect of business, except one: the area of people. And that is when the downward slide begins. The owner recognizes that, in spite of the dedication to excellence, things are not right. The shop owner has established the goals of the company and put everything in place. Everything is attainable. But it’s not working. Frustration sets in, and it’s not long before the owner begins to complain about the lack of performance and drive from the employees, which is the perceived root of the problem. Well, the root of the problem is the owner. We all know that running a business is not a walk in the park, but if your business is struggling, you, personally, are struggling. If your people are not performing the way they should, then you are not performing the way you should. Granted, there are employees that are a problem, and if that’s the case, they need to go. But even superstar employees will turn sour under poor leadership. There are endless issues and problems you encounter each and every day, and some of those problems are out of your control. But, excluding a cataclysmic event, you can trace most of your problems back to you. You are the shop owner, you are the leader. The strength of your business begins and ends with you. Given two equally talented ball teams, the difference between winning and losing is usually leadership. Employees need to know you care about them. The people you employ have vision and goals, too. Not the same as yours, but real nonetheless. One of your jobs, as leader, is to align their goals with yours. We throw this leadership term around a lot these days, and for good reason. It’s the most powerful skill you have in terms of getting the results for which you are looking. The horrible truth is there are too many bosses and not enough leaders. Anyone can be a boss. Bosses order people around. And people will follow, but not for the long term. A leader motivates others by understanding what drives the individual. A leader gives credit to others, never seeking gain at the expense of others. Next time you walk through your shop, pay attention to the mood of your employees. Are your employees laughing and talking to each other? You know, having a little fun at work. Do your employees look to engage in conversation with you, or are their heads buried under the hood of a car as you pass them by? Even worse, does everyone stop talking when you are around? These are signs that your employees are not engaged, which means they are not aligned with the goals and vision of the business, and you are not aligned with theirs. A leader finds out what’s important to others, and works to help them achieve it. Aligning the goals of the individual with the goals of the company will achieve great things. When employees are respected as people, they become motivated and perform at their best; not because they are told to, but because they want to. This is the highest form of team spirit and becomes your driving force toward success. This story was originally published by Joe Marconi in Ratchet+Wrench on October 1st, 2018

    • Article: Restoration for the Mechanic - modern repairs, old mechanic

      Restoration for the Mechanic Electrical issues on today’s cars have certainly taken  center stage.  Mechanical issues are still there too, but  it’s not uncommon to have a mechanical problem be  diagnosed, monitored, or calibrated by some electronic  means.  You just can’t get away from the electrical  if you’re in the automotive repair business these days.   It’s taken over just about every facet of the automobile.         Today’s mechanics have become something entirely  different from the stereotypical mechanic from just a  few decades ago.  It’s not that long ago when the  electrical section of the repair manuals were just a  chapter or two, today… its volumes and volumes of  schematics and diagnostic procedures.  I’m old enough  to remember when points and condensers were still  the norm, and I’ve watched the industry go from  electronic ignition to today’s electronic jungle of wires  and processors. We’ve definitely come a long way with  the technology.   Even though I work on all these newfangled electrical wizardry systems on the modern car, deep down I’m still the kid who got a kick out of tearing down an old junker and putting it back together.  Now, I’m surrounded by modules, proximity keys, and sensors.  Occasionally it’s kind of nice just to step away from the computer and just turn a wrench or two. I look forward to those simpler kinds of jobs, the ones that need a craftsman’s touch and not a box of transistors and capacitors to figure out what to do.  Back to a time when a driver was more mechanical involved in the process of operating the vehicle.   Heating vents with levers and cables, or a hand choke that needed just the right touch to get it started.  No electronics, no service light, just the essentials.  (For you younger techs, I’m referring to the days when you actually had to unlock a door with a key.)     I still marvel at the ingenuity and engineering of those times. I guess it’s one of the reasons why I like going to old car and steam engine shows so much.  It’s all about the mechanics for me.  Electronics are great, but to see the early mechanical devices that were commonplace a century ago still amazes me.  How they figured it out, and how they made it work is shear brilliance.  (If you ever get a chance to study some of those early mechanical systems, you might be surprised how things were accomplished prior to the computer age. It’s quite fascinating… well at least to me it is.)      It’s great to be able to step back once in a while and just be a mechanic.  Back when things were rebuilt and not just replaced with new. There’s a certain satisfaction in taking a broken mechanical device and making it functional again.  It’s those jobs that after you’ve wrestled the components into place, and everything is finished you realize that you’re covered in grease, but for some reason you’ve got this big smile on your face. It’s the look of accomplishment, a smile of pride in a job well done.  And while you’re cleaning up the tools, you look over at the finished project still smiling, knowing you’re done and can move onto the next project.  It just doesn’t compare to finishing up on a modern car when the last thing to do is watch that blue line steadily move across the computer screen, waiting for it to say “Task completed”.   Not that I’m putting down the modern car, no far from it.  It’s just nice to take a break once in a while from the technical mumbo-jumbo and just be a mechanic for a change.  Even though it’s pretty awesome to solve a difficult electrical issue, it’s hard to beat a good old fashion mechanical repair.  For me, when a restoration project shows up at the shop I get a chance to turn off the laptop and open the toolbox.   These restoration jobs are just as much for the customer as they are for me.  It’s a restoration of some of my old almost forgotten mechanical abilities. (Yea, I still got it…)     We put a lot of trust in the modern electronics, something the engineers and designers of those automobiles from a few decades ago never even though of.  Their own ingenuity and craftsmanship kept them going.  Components were built to be repaired not replaced.  I think it’s safe to say that a car from 50 years ago is more likely to start and run in another 50 years but I seriously doubt a car from today would have the same luck. There again, it might be something a technician/mechanic of that era might figure out how to do by then.  Me I’ll still stick with being a mechanic/technician … I still like the physical repair aspect of the job.     The future of electronics in today’s cars is constantly changing; sometimes we notice the changes while other times you can’t physically see them.  Sometimes all it takes is a little R&R on an old jalopy just to make me remember how far we’ve come.  In the meantime, the latest restoration job is done so it’s time to go for a test drive.    I’ll get back to the laptop and the modern car world just as soon as I get all the tools cleaned up… it might take a bit though … I’m still admiring the restoration job and I’ve got some more smilin’ to do.

    • Article: Zombie Cars - they're coming (updated older story)

      Zombie Cars   “Brains, Brains, we need Brains!”   Zombie cars?  What’s a zombie car?   Way back, when we used points and  condensers and later the basic  electronic ignition systems, cars didn’t  need brains (ECM – Electronic Control  Module), but that all changed in the  mid 70’s on some imports and pretty  much on everything else by the time  the 80’s came around.  Some of these  brains were only cursory, and didn’t  actually control the car, but merely  watched for emission issues, while others played a major role in the actual ignition spark or fuel delivery systems.     Most of the engines in those early years, still used the same basic type of distributor setups (with a few exceptions) as their earlier counterparts that used the old tried and true points and condenser type of ignition systems.  During those cross-over years it was rather easy to slap a different distributor in it, or change the existing points distributor over to electronic ignition (which worked quite well by the way).  These days...it’s not that easy.  These computer systems have become so entangled into the engine functions and nearly every other system that it’s impossible to bypass the fuel or ignition systems as we did years ago. However, there are still a lot of people out there that have hung onto some of the cars from that era.  Most likely they've been kept parked alongside the garage as a future project or hung onto for some sentimental reason.  Some (very few) are in great shape, others… well, they look like zombies already.     What makes them zombies?  The brain… the brain… they need brains!  Just this past week I had several of these faded paint monstrosities lined up in the parking lot. (They never come alone… always in a pack.) For starters an old dilapidated 1986 Dodge pickup with a slant six.  This old rusted, tilting to one side relic had been at another shop for a tune-up, but as the story was told to me by the owner, the other shop tried to start it when a fuel line ruptured and caught the old truck on fire. Luckily, they managed to get it out, but the damage was already done.  The main harness from the firewall to the distributor, coil, charging system, blower motor, oil sending unit, temp. sender, and the starter wiring were completely melted into an unrecognizable mass of plastic and copper.  It was my job to bring this dilapidated hulk back to life. However, the original spark control computer had melted as well, and was unusable. Worse yet, the brain was discontinued eons ago with no replacement parts anywhere to be found.  This zombie needs a brain, and there doesn’t seem to be an easy way to get one. At this point the only solution was to do away with the electronic brain and try to refit the old slant six with a much simpler ignition system from a decade earlier if at all possible.  A lobotomy if you will. (Dr. Frankenstein would be envious.)   Then there was this 2002 Mustang that moaned and groaned while dragging one foot into the shop.  It needed a new BCM (Body Control Module).  Call the dealer, call the parts warehouse, call everybody!  Anybody!  Is there a brain for this car?  Nope, discontinued.  Seems this particular BCM was a rather rare brain out there in zombie land, and at the time, nobody was setup to rebuild them.  It seemed this car was destined to wander the city streets with the rest of the zombie mobiles. At the same time this was going on, in comes a 1982 Ford Bronco with the original Variable Venture carburetor still on it. Ok, not a brain, but just as bad.  It qualifies as a zombie for sure.  Trying to find a suitable replacement these days is a challenge. Ten or twenty years ago this would have been no problem to find a carb. kit (if you dared) or the Holley conversion kit for it, but not today.     This trend of bringing back the dead looks like it’s only going to turn into the next zombie apocalypses.  As these electronic systems get more and more complex the likely hood of your family truckster turning into a zombie is just a matter of time as each new model comes out.  In some ways, I believe the manufacturers have thought this out long before there was a potential of these cars becoming zombies.      In my youth it was nothing for me and a few friends to grab an old car out of a junk yard and raise it from the dead.  Ya just had to throw a few shots of gas down the carburetor, add a few wires and a fresh battery and fire it up.  The rust would fly, the engine would clatter, the smoke would billow out from under the hood,  as the exhaust roared out of every crack in the manifold.  Those days are long gone now.  They may have engineered a longer lasting engine, better paint, and for the part, the interior can hold up to the ravages of time, however, the electronics, are their weakness.      Although, these zombie mobiles seem to be coming out of hiding more often than ever before. Reviving some of these early electronic zombies may happen, but on the other hand, it may be a futile effort. The truth of the matter is… these resurrections are not as easy to do as it was so many years ago. There are countless problems that have to be overcome to bring some of these rusted heaps back among the living, especially if you’re in an area that requires emission testing.  Just trying to bypass some of those early electronic brains when a replacement part can’t be found can be a real challenge. The good news is that there are a lot of guys out there tearing these brains apart and rebuilding them.  But even then, there are some zombie cars that will never make it and eventually die from the lack of a brain, while others wander aimlessly from shop to shop still searching for their elusive electronic gray matter.    Even after you manage to find a brain for these living dead vehicles it’s likely something else is going to go wrong.  After all, being cast aside for so long, all the hoses, belts, and gaskets have dried up.  Something will more likely fall off just like you would expect from any other zombie wandering around.  And, you know, just as soon as the latest zombie joins the living something will undoubtedly come tumbling to the shop floor.  Whether it’s coolant, oil, a belt, or perhaps no#2 connecting rod,  something is not going to stay in place.  Just like in every zombie movie I’ve ever watched,.one of them will always have an arm or leg falling off.  It sure seems that these zombie cars follow right along with that same affliction.       It’s safe to say, these relics of the early electronic era of the automotive world are in some respects the car equivalent of a zombie: half dead, half alive…and in search of a brain they may never find.  So don’t be surprised if you’re at the next traffic light when an old faded-rusty-dented car with a shattered windshield, screeching brakes, with plumes of dense low hanging smoke creeping along with it, don't be alarmed, it’s just another car beginning its transformation into a "ZOMBIE CAR".

    • The Road to Great Technicians Webinar With CARQUEST’s Chris Chesney

      On June 20, the Automotive Service Association (ASA) hosted a webinar called “The Road to Great Technicians” with Chris Chesney, senior director of customer training for the CARQUEST Technical Institute.  Written by Chasidy Rae Sisk * Attendees qualified for one credit from the Automotive Management Institute.  After ASA Vice President Tony Molla introduced the webinar’s presenter, Chesney recounted his collaboration with the National Automotive Service Task Force (NASTF) to identify the Road to Great Technicians. They began in March 2016 when NASTF’s Spring General Meeting focused on the topic of building a road to great technicians. Chesney was asked to explain the current state of the aftermarket training industry. He defined the current state of aftermarket training as a lack of industry standards and a structured career path, unorganized training offerings, and disjointed efforts by industry organizations. However, he also identified many good building elements. Current problems in the industry include the inability to find new talent, graduates not performing to industry standards, an inability to afford techs and the amount of time is takes to replace a technician or advisor who leaves a company because companies do not build bench strength. Chesney stressed, “You have to invest in those new technicians, but many shops cannot find someone who can perform out of the gate, so we need to focus on growing our own and building our bench strength to overcome this problem. We have a need now for the next several years. Reports indicate that we need 80,000 technicians each year, but only 25,000 are being produced.” Chesney identified the aging workforce, oncoming tidal wave of technology and lack of a structured career path as reasons for the significant needs for technicians. Focusing on the influx of technology, he explored the unseemly amount of data that is transferred within modern vehicles. “It’s not the problem of education,” he said. “It’s our problem, and we’re going to look into that.” Chesney presented a picture of the Technician Life Cycle, which included the following seven steps: secondary shadowing, post-secondary intern, entry-level apprentice, technician, senior technician, master technician and specialist; however, he noted that this does not include possible “off ramps” on the Road to Great Technicians. Occurring after an industry professional becomes an entry-level technician, these “off ramps” include in-service continuing education and higher education, which can offer technicians a variety of paths to pursue in their careers, ranging from master technician to shop foreman to shop owner or even becoming an engineer for an OEM.  In a January 2018 meeting, the education team at NASTF identified a subcommittee of industry experts tasked with creating a framework of education around the life cycle of a technician and other job roles within the industry. This framework is intended for curriculum providers to use in order to offer a career pathway that means something to the industry and is transferrable throughout the industry. The group began with the vision that they would prescribe degrees of competencies at every skill level, focused on the safety and reliability of the ground vehicle fleet. This Road to Great Technicians team consists of NASTF Chair Mark Saxonberg, Toyota’s Jill Saunders, WTI’s Rob Morrell, CTI’s Chris Chesney, NACAT’s Bill Haas, of Diag.net’s Scott Brown, WTI’s Mark Warren, NASTF’s Donny Seyfer, ASE’s Trish Serratore, S/P2’s Kyle Holt, DrewTech’s Bob Augustineand Cengage’s Erin Brennan. Exploring possible solutions to the industry’s problem, this group defined 13 solution elements, starting with new and enhanced communication with parents and influencers of peripheral students, early engagement with tactile students in middle and high school, support of STEM and development of a well-articulated career path with clear opportunities for advancement and growth that students and parents can see. The industry also needs to get involved with vocational education content to ensure these programs provide the right skills to students.  Chesney explained, “They’re producing the wrong technicians because we aren’t involved. We have to be involved. We need to design a curriculum for schools and employers to ensure that, regardless of where technicians work, they are uniformly trained for the skill level. We have to provide people with the opportunity to grow throughout their careers.”  The team also believes that the industry needs to provide internship experience, develop programs to help in-service technicians become mentors, and ensure that testing and certification programs are uniform and tiered to provide milestones for achievement. Employers also must find ways to provide wages and benefits that are competitive with other industries attracting the same individuals.  “As technicians progress through their career, it is imperative to communicate career options to ensure they don’t leave the industry,” Chesney elaborated. “Vehicle technology has accelerated to unprecedented levels, necessitating faster and more thorough technician skill development to ensure public safety. To add further credibility and value to the process, NASTF is encouraging practical examinations similar to other safety-related skills as a means to verify requisite skill level attainment. Currently, this is not regulated and we cannot keep up with the advancing rates of technology, but we need a way to prove our skills and be prepared for what’s coming, not merely what is on the road right now.” The current state of industry education is outcome-based and not sufficient to serve today’s technology. The future of education must be competency-based with a focus on mastery of skill and validation of a technician’s mastery and development of skills that are recognized and transferable. A competency-based education offers a variable class structure and the ability to test out of the subject matter at different levels, enabling students to finish as they are able. The Road to Great Technicians team defined a new NASTF Technician Life Cycle that includes seven steps: apprentice technician, maintenance technician, service technician, repair technician, diagnostic technician, master technician, and specialist technician.  According to Chesney, “Each step would require a variety of requirements as far as training and experience. They would also require mastery of competencies using curriculum provided by the industry, to include mentoring, demonstrated skills and self-paced curriculum. Finally, technicians seeking to advance would prove their skills through oral and hands-on exams.” Continuing the work they have started, the team plans to provide the industry with a white paper by the end of the year, but they encourage the industry to comment and opine. While the team will be limited in size in order to maximize effectiveness, they encourage industry professionals to join NASTF and the NASTF Education Team.  The group’s vision for the future of automotive education culminates in the idea of the Automotive Institute of Science and Technology, which would include a pathway education in a project-based environment. In ninth and 10th grades, students would sample each pathway through projects designed to highlight the different aspects and career fields before choosing a specific pathway in 11th grade to focus on in their final two years of high school. Their choices would be automotive technology as a trade, business, or engineering. While obtaining their associates degree, students would enter the discipline of their choice, working in shops to gain practical experience while simultaneously acting as mentors to younger students. Chesney concluded the webinar with a question and answer session.
