Inspection and Maintenance Procedures
Starting Clutch
Visually inspect the spline and clutch jaws for signs of uneven wear, nicks, burrs, or other physical dam-
age. Inspect the hydraulic cylinders for leakage.
Inspect the linkage, pins and hardware for security. Check the clearances of the clutch jaws in the en-
gaged and disengaged positions. Check the limit switch to see that the switch is operating at the proper
setting.
Torque Converter
Check torque converter unloading solenoid valve 20TU plunger for freeness of operation. Apply sili-
cone grease to plunger rod.
Ratchet System
Check ratchet pump motor (88HR) for cleanliness of commutator and brush condition. Check relief
valve setting (VR-5) and obvious oil leakage of external piping. Ratchet pump should show no signs of
overheating.
Accessory Gear Train
Through the various inspection openings, visually inspect the gears for pitting, scoring, galling or broken
teeth. On scheduled major inspections, remove the accessory gear case cover and check the condition
of the gears and bearings.
Prior to complete reassembly, inspect lube oil spray with pump operational in regard to oil nozzle plug-
ging and direction of oil spray.
FIRE PROTECTION SYSTEM
IMP–14
**WARNING**
Fire suppressant, in a concentration sufficient to extin-
guish fire, creates an atmosphere that will not support
life. It is extremely hazardous to enter the compart-
ment after the system has discharged. Anyone ren-
dered unconscious by fire suppressant should be res-
cued as quickly as possible and revived immediately
with artificial respiration or by mouth-to-mouth re-
suscitation. The extent and type of safeguards and per-
sonnel warnings that may be necessary must be de-
signed to meet the particular requirements of each sit-
uation. It is recommended that personnel be adequate-
ly trained to cope with such an emergency.
