6.8 electric clutch adjustment

ADJUSTMENT NUTS

The electric clutch serves two functions in the operation of the mower. In addition to starting and stopping the power flow to the cutter blades, the clutch also acts as a brake to assist in stopping blade rotation when the PTO is switched off or the operator presence circuit is interrupted.

When the clutch is disengaged, the air gap between the armature and rotor must be adjusted to fifteen thousandths of an inch, 0.015, for proper operation. The airgap adjustment is made at three bolts on the clutch. There are three inspection windows, one next to each adjusting bolt. See Figure 6-3.

Figure 6-1. Clutch Air Gap Adjustment

1.Locate the inspection windows on the clutch.

2.Place a 0.015 feeler gauge in the slot between the rotor and the armature.

3.Tighten or loosen the adjusting bolt as needed to acheive the 0.015 inch airgap. See Figure 6-4. Perform this operation at all three inspection windows.

This adjustment should be done every 500 hours of operation or annually, whichever comes first. In cases where the machine is heavily used, airgap settings should be checked more often.

If the air gap is too narrow, the clutch armature may drag when disengaged, resulting in premature failure.

If the air gap is too wide, the clutch may be slow to engage as the magnet must pull the armature in from a

greater distance.
