c. Lubricate two drag link grease fittings
(13) with grease (Item 15, WP 0235 00).
d. Lubricate steering column fitting (14) and
two U-joint grease fittings (15) with
grease (Item 15, WP 0235 00). Observe
purging from all seals until new grease
comes out. If grease does not purge,
manipulate U-joints until purging occurs.
CAUTION
DO NOT use an automatic or power grease gun on fitting on trunnion side
of steering gear because the rate of flow is too high. High flow rate could
force grease inside high-pressure seal, contaminating hydraulic system and
promoting seal leakage.
e. Lubricate grease fitting (16) on trunnion
side of steering gear, near output shaft,
with grease (Item 15, WP 0235 00).
