Maintenance Instructions
1. Checking tightness of bolts after the fluid coupling has been in service for a
few weeks, check that the screws in the collar, pulley sheave, hub and bearing
housing are tight. If necessary, tighten the cap screws to the specified torque
valves.
2. Checking filling at intervals of about 12 months, check the level of oil in the
fluid coupling and, if necessary add oil to make up the level.
Add only the same grade oil as that used for the initial filling of the couplings.
