The Flywheel Grinder … your profit pal

The Flywheel Grinder … your profit pal

As you know the flywheel grinder in your shop should be one of the most profitable machines in your business. With basic skills, training and the following information, just about anyone in the shop can grind a flywheel properly. The set up is simple and the job itself is very fast. In most cases you should be able to average about $100 per hour if you can keep the work coming in from your customers.

Here’s a quick overview of how to set up and use your flywheel grinder.

Tips for Using CBN Flywheel Grinding Wheels

CBN Flywheel Grinding Wheels are a relatively new addition to the flywheel grinding arsenal. Since they are so new, there’s been some confusion about them that we’d like to clear up.

  • CBN Flywheel Grinding Wheels are constructed as an aluminum  or graphite substrate and form into a cup (type 11) with CBN (cubic boron nitride) material cemented to the flair.
  • CBN Flywheel Grinding Wheels are recommended only for use on ferrous materials; specifically cast iron.
  • Because there is no real porosity in the CBN Flywheel Grinding Wheel, use them with large amounts of clean flywheel grinding coolant pointed at the wheel contact area. This will lubricate, cool and carry away swarf created during grinding. We also suggest you use a filter sock on the coolant returning to the sump to help minimize swarf returning to the wheel through the sump. Never crowd the machine or use a power feed while grinding as this will build heat and chunk the wheel.
  • CBN Flywheel Grinding Wheels are great for finishing 90 degree steps in flywheels.
  • CBN wheels create less dust
  • CBN wheels can last 8 times longer compared to vitrified wheels on average.
  • CBN wheels will last longer and create less heat when used with fresh, clean coolant.

Straight Talk About Your Surfacing Machine

Today we’re going to talk about resurfacing machines for cylinder heads and blocks. These machines come in variety of styles and configurations as well as many colors. There are belt grinders, dry grinders, wet grinders, broaches and mills. There are different designs from under-head to over-head types. These machines use coated or formed abrasives, some use carbide and later styles or models use CBN or PCD, some use coolant and some are operated dry. Despite these differences, they all have two things in common; they make a warped surface flat and they need the same care and attention when it comes to the daily maintenance necessary to maintain their accuracy and dependability.

6 Essential Summer Car Care Tips

Road trip season is almost here! Make sure your vehicle is ready to handle some sun-drenched driving. Summer’s high temperatures, flurries of dust and dirt, and the occasional rain can all take a toll on your vehicle’s most important systems. With these essential services, though, you can better prepare your car and help it run smoothly and safely through summer and into fall. Ready to get started?

Tip #1: Get your oil and oil filter changed. This is particularly important if your last oil change was awhile ago, because intense weather conditions of any kind (wet, hot, or cold) can put extra demands on your oil and oil filter. Your oil works to keep your engine parts lubricated while the filter works to capture harmful debris, dirt, and metal fragments that have finagled their way into the oil system. A clean filter means more material gets picked up. More material getting picked up means cleaner oil. Cleaner oil means a healthier, happier engine!

Tip #2: Double-check your fluid levels. Seasonal weather changes can lead to low transmission fluid, power steering fluid, coolant, and even windshield wiper fluid, so check them all! Coolant fluid, in particular, is an especially important one to keep an eye before the heat of the season. According to the National Institute for Automotive Service Excellence, the greatest cause of summer breakdowns is overheating. If you’re not comfortable performing these checks on your own, stop by your nearest Firestone Complete Auto Care and let one of our technicians take a look. 

Tip #3: Check and monitor your tire pressure. Between hitting hidden potholes and dealing with difficult road conditions, your tires deserve a good check-up. The truth is, tires lose or gain pressure daily depending on the outside temperature. In cool weather, for example, a tire will typically lose one or two pounds of air per month. Make sure your tires (including your spare!) are properly inflated before hitting the road for a big summer road trip, because tires with low air pressure tend to wear out much more quickly. Get started by finding your vehicle’s recommended tire pressure.

Tip #4: Evaluate your alignment. If your car pulls to one side, your steering wheel vibrates, or your steering wheel isn’t centered when you’re driving straight, get your vehicle’s alignment checked out. Alignment can be thrown off by general wear and tear, as well as run-ins with rough roads, potholes, and curbs. Proper alignment can help extend the life of your tires, make for a smoother ride, and even save you a few bucks on gas. A quick check-up can let you know if your car is due for an alignment service.

Tip #5: Test your battery. “Summer heat accelerates the rate of fluid loss and resulting oxidation of battery components, which can leave you stranded without warning,” says Steve Fox, Director of Automotive Services for AAA Oregon/Idaho. “Most people don’t realize that heat is the number one cause of battery failure and reduced battery life,” he adds.

Tip #6: Get your brakes inspected. At the end of the day, is there anything more important than good brakes in your vehicle? Stop-and-go traffic, long holiday road trips, and inclement conditions may have done a number on your brakes. Whether your brakes are making eerie noises or demanding extra pressure, it’s may be time for some fine tuning.

You can’t always guarantee that life will run smoothly, but you can do your best to make sure that your car does. Basic maintenance services, like oil changes, are the perfect place to start before summer. Firestone Complete Auto Care’s full-service oil change includes an oil and oil filter replacement, a top-off of important fluids, and a courtesy 19-point inspection. If there’s something “off” with your brakes, battery, alignment, or tire pressure, there’s a good chance our technicians will catch it during the courtesy inspection and bring it to your attention. Summer car care couldn’t be more convenient! 


Visually Identifying Your Flex-Hones®

Problem: You have several flex-hones on your bench. They're all about the same size but you know they aren't all the same grit or the same abrasive. How can you tell which one is which?

Solution: Brush Research has made identification of its Flex-Hones quick and easy by color coding the stem to indicate the abrasive formula and the tip to identify the grit. 

Selecting Honing Stones for Your Next Job

Selecting Honing Stones for Your Next Job
Selecting the right honing stone for the material being worked should be relatively easy. Though when you look at the Goodson catalog it can seem a bit overwhelming since we do have over 150 different honing stones listed just for cylinder honing. Add in rod honing, align honing, lifter bore honing and valve guide honing stones and you’ve got quite the assortment to choose from.

Honing Oils 101

Honing Oils 101

The importance of honing oil is often underestimated when calculating the cost of a cylinder honing job. Everyone sees the labor cost and the cost of the abrasive and tooling, but what about the honing oil you use? How does that factor in? 

In terms of dollars and cents honing oil is a tiny fraction of the overall cost of cylinder honing; 1% or less of the total process cost. But when it comes to the quality of the job, the rate of abrasive consumption and the speed of the honing cycle, honing oil is king.
