Using a straight edge, warping should be less than 0.010in. If such were the case it would indicate the release bearing is adjusted too close or is constantly riding the clutch fingers.Ģ) Check the pressure plate for warping. A lathe will not provide a sufficiently flat surface for the clutch disc to seat and operate properly.ġ) The fingers of the cover assembly-the tips where the release bearing makes contact with them-should not exhibit any grooving or excessive wear. As a general rule, if there’s evidence of bluing on the backside of the flywheel, replace it.Ĥ) Flywheels otherwise may be resurfaced up to a maximum of about 0.030”.ĥ) Finally, ensure the flywheel is surface-ground and not machined on a lathe. This judgment is based on how much heat the system has been exposed to and how much warping is present.ģ) If severe warping, bluing, or smearing is visible, the flywheel must be replaced. Flywheel warping should not exceed 0.015 to 0.020in.Ģ) Some lightweight or scalloped flywheels may not have sufficient surface material to allow re-grindi ng. The lighter the flywheel, the more susceptible it will be to warping.

Here’s how to do it.ġ) Flatness of the flywheel is critical. In addition to adopting smarter driving techniques that prolong clutch life, it’s smart to know how to inspect and maintain the racing clutch assembly. And transmissions with gears removed, like those running 3 rd and 4 th gears only in an effort to reduce drag and save a little weight, sustain appreciably more slippage on takeoff than desirable. Higher gearing (lower numerically) also provokes clutch slippage during take off. Heavier cars, for example, invite clutch slippage to gain momentum. Other factors that have a detrimental effect on clutch life include the weight of the vehicle, gearing and the number of gears employed. And getting the car rolling and engaging it without hesitation is a good start. Obviously, clutch life can be prolonged extensively by minimizing clutch slippage on takeoff. Excessive slippage will cause premature warping, especially in lighter components. Of course, the amount of wear on all racing clutches is largely determined by how much the slippage is provoked during takeoff. To minimize clutch damage during loading and unloading without crew members it pays to use a winch. So he slips his thin, thin lightweight clutch a couple of times and as it colors dark blue its end is nigh. Without crew members or a winch to assist, he is often obliged to load the car by himself. Probably the most persistent clutch killer strikes when the racer is on his own. In either case, to reduce these often unnecessary costs here are a few tips intended to prolong the life of the racing clutch.

In all likelihood if you added a little strength to the unit you would probably gain 50 percent greater clutch longevity without any perceptible loss in power. You may think racers would resent these dubious practices, but there is no evidence to suggest they do. A stroke of marketing brilliance some might say! Racer purchases ultra light clutch, racer quickly destroys ultra light clutch, racer purchases successive ultra light clutch.

Racers frequently face the inconvenient fact that some clutch-flywheel assemblies are so light they fail prematurely, often during the taxing process of getting the car into the trailer.Ĭuriously, most professional clutch makers agree that you quickly reach a point where the ultra light clutch unit has no advantage at all and instead its arch attribute, lightness, undermines the process bringing decreased durability.
