Adjusting the Electric Clutch

The clutch is adjustable to ensure proper engagement and
proper braking. Check adjustment after every 100 hours of
operation.
1. To adjust clutch, tighten or loosen lock nuts on flange
studs (Figure 34).
2. Check adjustment by inserting feeler gauge through
slots next to studs (Figure 34).
3. The proper disengaged clearance between the clutch
plates is 0.012–0.024 inch (0.30-0.60 mm). It will be
necessary to check this clearance at each of the three
slots to ensure the plates are parallel to each other.
