Transmission Clutch Running Clearance - Check

Usage:

525B 3KZ


Use this procedure to check for proper clutch assembly.

------ WARNING! ------

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.

----------------------

  1. The operator should lower the grapple and the decking blade to the ground.

  1. Put blocks in front of the wheels and behind the wheels.

  1. Install the steering frame lock.

  1. Perform the following procedure in order to warm the transmission oil:

    • Engage the parking brake.

    • Lower the implement.

    • Push the transmission speed upshift control switch into the fifth gear position.

    • Place the transmission direction control switch in the FORWARD position.

    • Operate the engine at high idle. Monitor the gauge for the torque converter oil temperature that is on the dash panel. Reduce the engine speed and shift the transmission into the NEUTRAL position when the gauge enters the high temperature area. Shift the transmission back into gear once the temperature returns to normal.

  1. Allow only authorized personnel on the machine. Keep unauthorized personnel off the machine and in clear sight of the operator.

Note: All tests and all adjustments must be made while the transmission oil is at normal operating temperature.

Typical Example

(1) Clutch oil passage. (2) End plate. (3) Lock ring. (A) Running clearance.

  1. Position the assembled clutch group so that the shaft is in the vertical position. The end plate of the clutch that will be measured should face upward.

  1. Make sure that end plate (2) is free.

  1. Position the tip of a dial indicator on end plate (2) and zero the dial indicator.

  1. 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.

  1. End plate (2) should move and end plate (2) should contact lock ring (3). When the end plate contacts lock ring (3), read the movement of the dial indicator. This 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.
