Maintenance

Electric Clutch Adjustment

No adjustment necessary. However when the clutch brake has worn to the point where the clutch no longer engages consistently, the shim can be removed to extend the clutch life.

Removing the Shim:

1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake. Allow the machine to cool completely before starting these instructions.

2.Using a pneumatic line, blow out any debris from under the brake pole and around the brake spacers.

3.Check the condition of the wire harness leads, connectors, and terminals. Clean or repair as necessary.

4.Verify that 12V is present at the clutch connector when the PTO switch is engaged.

5.Measure the gap between the rotor and armature. If the gap is greater than .04 inch (1 mm), proceed with the following steps:

A.Loosen both brake mounting bolts one-half to one full turn (see Figure 24).

Note: Do Not remove the brake pole from the field shell/armature. The brake pole has worn to match the armature and needs to continue to match after the shim is removed to ensure proper brake torque.

B.Using needle nose pliers, or by hand, take hold of the tab and remove the shim (Do Not discard the shim until proper clutch function has been confirmed).

C.Using a pneumatic line, blow out any debris from under the brake pole and around the brake spacers.

D.Re-torque each bolt (M6 x 1) to 10 ft-lb (13 N-m) +/-0.5 ft-lb (0.7 N-m).

E.Using a 0.010 inch thick feeler gauge, verify that a gap is present between the rotor and armature face on both sides of the brake pole as shown. (Due to the way the rotor and armature faces wear (peaks and valleys) it is sometimes difficult to measure the true gap.)
