SECTION 4: Installation (continued)
4.2.6. The set or trip torque can be checked by adapting a torque wrench or spring
scale to the dial. Set torque should be within +/-15% of the started value.
NOTE: Set torque is defined as the torque which causes the first .001/.003"
movement of the rollers out of the detent. This can be checked with a dial
indicator on the switch actuation plate.
The trip torque (to cause a complete disengagement of the clutch) will be up to
30% higher than the set torque (initial movement).
4.2.7. Disassembling clutch for maintenance
4.2.7.1. Remove the dowel between the clutch body and output adapter. Do not
remove the dowel pins between the output adapter and indexer. Do not
disassemble the spring adjusting nut from the clutch housing body.
4.2.7.2. Carefully unfasten and remove clutch bolts so that the body mounting is
released slowly to prevent bodily injury.
4.2.7.3. Remove the clutch body assembly from output adapter.
4.2.7.4. Clean off any contaminates or residues and inspect all parts for any wear.
4.2.7.5. Apply Molykote™ grease to detent driven plate, detent pockets, rollers
and bearings. Reassemble clutch.
