TM 9-2815-220-24 ENGINE ABNORMAL OIL PRESSURE 0018 00 MALFUNCTION 11: Generator oil pressure abnormal (650 Ampere generator, PN 11655469 only). PROBABLE CAUSE CORRECTIVE ACTION b. (Continued) Generator oil pump failure. (2) Replace generator (WP 0051, Generator Replacement (650 Ampere) (2CA). c. Drive clutch failure. (1) Perform Clutch Test as follows: PROCEDURE OBSERVATION ANALYSIS If slippage occurs below 167 foot pounds, drive gear assembly is defective. Torque check (generator removed). Check slip torque of drive gear assembly with generator coupling tool and torque wrench (300 foot- pound capacity). Note if there is slippage of the drive gear while increasing torque to 167 foot pounds. If no slippage occurs below 167 foot pounds, slip torque is acceptable, but gear assembly may have other damage (low torque rate). Proceed to 2 below. If rotation is more than 8°, but less than 17°, drive gear assembly is satisfactory. Check torque rotational deflection rate. Using tool and torque wrench as in 1 above, apply 167 foot-pound torque. Note deflection in degrees from zero torque to 167 foot-pound torque. If rotation is greater than 17°, or less than 8°, the drive gear assembly is defective. END OF WORK PACKAGE WP 0018 00-6
