Illustration 2 g00861070
Typical example (10) Hub assembly (11) Ring (12) Clutch pack (13) Piston (14) Passage
Position the assembled clutch group with the shaft in the vertical position. Position the hub assembly of the clutch that is being measured so that the hub assembly faces upward.
Make sure that piston (13) moves freely.
Position the tip of a dial indicator on the flat of piston (13) at location (B). Zero the indicator.Note: Ensure that the tip of the indicator is parallel with the centerline of the shaft assembly.
Personal injury can result from applying air pressure without the lock ring securely in place. Make sure the lock ring (11) is securely in place before applying air pressure to the clutch pack.
To check the running clearance for the clutch packs, apply approximately 140 kPa (20 psi) air pressure to passage (14) for clutch pack (12) .
Piston (13) and clutch pack (12) should move up. Determine the amount of piston movement from the reading on the dial indicator. This is the running clearance for the clutch pack.Repeat Step 1 through Step 6 in order to determine the running clearances for the remaining clutch packs.
