Overload Release Clutch Torque
Frequent overload tripping that cannot be corrected by feed rate and/or pond depth adjustments
may be due to an incorrect torque setting of the overload release assembly. The release
assembly torque should be checked and adjusted, if necessary, as follows:
1. Remove gearbox drive cover.
2. Remove torque cam from overload release clutch.
3. Insert socket key of torque wrench, 13147-00 (included in tool kit 14795-00), into keyway of
overload release clutch. Exert sufficient force on torque wrench in a clockwise direction (when
facing clutch) to release the clutch. Release should occur at 335 in. lbs. for 52:1 gearbox or
200 in. lbs. for a 125:1 gearbox.
4. Reset clutch as follows:
a. Rotate clutch hub until cam roll pin hole and hub keyway are aligned with set screw hole
(stamped 22 on overload clutch housing).
b. Turn T-handle reset screw (Figure 5014-2) clockwise (inward) approximately 2-1/2 turns
until a click is heard, indicating that the clutch is reset.
CAUTION! When Turning Reset Screw Clockwise, Do Not Exceed Three Turns
After Slight Resistance Is Felt, As Excessive Tightening May Damage The
Clutch’s Internal Components.
