Typical Example (1) Clutch oil passage. (2) End plate. (3) Lock ring. (A) Running clearance.Use this procedure to check for proper clutch assembly.
Position the clutch assembly so that the shaft is in the vertical position. The end plate of the clutch that will be measured should face upward.
Make sure that end plate (2) is free.
Position the tip of a dial indicator on end plate (2) and zero the dial indicator.
Personal injury can result from applying air pressure without the lock ring securely in place. If the lock ring is not secure, the end plate and discs can suddenly come out with great force. Make sure lock ring is securely in place before applying air pressure to clutch pack.
Apply air pressure of approximately 140 kPa (20 psi) to appropriate passage (1) which is in the shaft for the clutch that is being checked.
End plate (2) should move and end plate (2) should contact lock ring (3). When the end plate is contacting lock ring (3), determine the distance that the end plate has moved from the dial indicator.
Release the air pressure in order to allow the dial indicator to return to zero.
Press down on end plate (2) in order to remove the free play.
Use the dial indicator to determine the distance the end plate (2) has moved.
The sum of the measurements taken in 5 and 8 is the running clearance of the clutch pack.Note: Even though running clearances on used clutch packs may be within the specification, one disc or two discs could be worn. Disassembling the clutch pack and individually measuring each disc for wear is the most effective way to measure clutch wear.
