What is clutch pack clearance?

In a torque converter, clutch release clearance (CRC) is the distance that the torque converter clutch piston travels from the release to the apply position. Giving a clutch pack . 008” to . 009” of clearance for each friction will usually yield good results, although there are a few exceptions.

What are the three ways to adjust clutch pack clearance?

Three common methods are shown here: first, measuring the change in cable length when the clutch lever is operated; second, measuring between the adjuster nut and lever; third, measuring between the adjuster nut and cable stop.

What could be the result of insufficient clutch pedal clearance?

The clearance, or clutch free-travel, re-leases the fork fully when the clutch is engaged. If there’s not enough clearance and the fork does not release completely, the clutch might remain partially disengaged, which causes slippage, excessive wear and heat build-up.

What can too much clutch pedal free play cause?

On the other hand, too much free play can cause clutch drag, making your car creep forward while changing gears, which can be troublesome in heavy traffic. Therefore adjusting your clutch pedal and achieving the correct amount of free play is very crucial.

What is a likely cause of a vibrating clutch?

When your clutch pedal vibrates, that means the clutch disc is losing its grip on the flywheel intermittently. Possible causes of vibrating or chattering include: Clutch disc lining (friction material) worn out. Clutch disc lining burnt or contaminated with oil.

Why is my bite point so high?

A bite point that is high up the clutches working travel (close to where the clutch stops before removing your foot) may be an indication that the clutch is worn and close to need replacing. This is only an indication however as it may simply need adjusting as every cars bite point is in a different location.

Where should a clutch biting point be?

Slowly raise the clutch pedal, a millimetre at a time, until you feel the vehicle begin to strain against the handbrake. This is known as the vehicle’s biting point. On older cars with worn clutches, this point might be quite high up the cutch’s working travel.

How much free play should be in the clutch pedal?

Too much free play and the pedals feel loose or spongy. Too little, and it’s difficult to press them and get the brake and clutch systems to engage. Most brake and clutch pedals should have just a little bit of free play, usually about a centimeter, which is less than half an inch.

What is the result of insufficient clutch pedal clearance?

Why does my clutch shudder when I pull away?

Clutch Judder Definition: Clutch judder is caused by the clutch components and the flywheel not meeting concentrically or mating properly. This generally happens after the vehicle has come to a complete stop and then engaging the clutch during take-off.

Do you hold clutch at biting point?

Use the clutch to hold your car on a hill If you have to stop behind traffic while going up a hill, you need to make sure your car doesn’t start rolling backwards. Many drivers will do this by holding on to the clutch biting point to keep themselves steady on the incline.
