PROBLEM
POSSIBLE CAUSES
SOLUTIONS
1. Lubricate clutch housing.
2. Check for excess clutch oil,
overfilling can cause drag on
high speed clutch parts. A typical
oiled/lubricated wrench requires
1/2 ounce (1.5 ml) of oil.
Grease lubrication:
Heat is generated due to
insufficient grease in the chamber.
Severe operating conditions may
require frequent lubrication.
