Clutch Assembly


It always makes good sense to mark parts before disassembling them. Clutch parts are balanced at the factory while on the engine. If the clutch cover is to be used again, it should be replaced in its original position. Make a centerpunch mark on the flywheel and on the clutch.

Use a HEPA vacuum to vacuum any asbestos dust from the assembly before disassembling it. Asbestos fibers can pass through a regular vacuum bag.

Use an aligning arbor to hold the disc while removing the clutch cover.

This will prevent it from falling accidentally. Unbolt the pressure plate bolts evenly to prevent bending the plate when the last bolt is removed. Carefully remove the assembly. Be careful not to drop the parts; they are heavy.

Inspect the clutch parts for damage. You will want to determine the cause before replacing the parts. A repeat failure must be avoided.

Use hot soapy water, brake parts cleaner, or alcohol to clean off any grease from clutch parts. Metal surfaces can be deglazed with sandpaper.

Do not wash clutch parts in solvent. Solvent contains oil that will be absorbed into the friction surfaces of the metal.

A clutch cover assembly is usually replaced when a disc is worn. If it is unworn, it may be reused. If you choose to reuse a clutch cover that appears to be in good condition, inspect the pressure plate to see that it is flat.

To replace the clutch assembly:

  • Install the clutch cover.
  • Install the clutch disc.
  • Attach the disc and clutch cover to the flywheel.
  • Align the punch marks on the flywheel and clutch cover if the parts are being reused.
  • Align the clutch disc.
