Exmark 000 & higher, 920 manual Electric Clutch Adjustment, Removing the Shim

Figure 26

3.Gap measures 5/8–3/4 inch (16–19 mm)

4.If the parking brake does not hold securely an adjustment is required. To adjust the brake, loosen the jam nuts on the brake linkage rod. Turn the brake linkage rod clockwise to decrease the gap and counterclockwise to increase the gap (seeFigure 26).

5.Tighten the jam nuts.

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 28).

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.
