Chassis Lubrication - Pontiac 1957 Owner's Manual

The car should be lubricated at end of the first 1,000 miles and there-
after at 2,000 mile intervals, except when driven under the conditions
outlined above.
CHASSIS LUBRICATION
MANUAL STEERING GEAR-Lubricant change is not necessary
unless the unit is disassembled for rep;"ir. At each chassis lubrication,
unit should be checked for leaks. If there is evidence of leakage from
the steering gear, the leak should be corrected and All-Season Steering
Gear Lubricant added to bring to proper level. If unit does not leak,
it is
only necessary to check level once yearly (preferably in the fall).
POWER STEERING-If there are any leaks in the system, they
should be corrected. Add fluid recommended for Hydra-Matic (page 31)
to bring level up to mark near top of reservoir. (Hydraulic fluid also
lubricates gear.) In an emergency, a good grade of S.A.E. lOW oil
may be used: replace with specified fluid as soon as possible. It is not
necessary to change fluid unless unit is disassembled for repairs.
SYNCHRO-MESH TRANSMISSION -Lubricant change in the
Synchro-Mesh transmission is not recommended unless repair work
is being done. Check transmission for leaks at each chassis lubrica-
tion. If there is evidence of leakage the leak should be corrected and
lubricant added if needed. Refill capacity is 272 pints. .
Use Extreme Pressure Gear Lubricant or Multi-Purpose Gear Lubri-
cant S.A.E. 80 or 90 (no special additives to these lubricants are re-
quired or recommended).
REAR AXLE-Lubricant change in the rear axle is not recommended,
unless repair work is being done. The rear axle should be checked for
leaks at each chassis lubrication. If there is evidence of leakage the
leak should be corret:ted and lubricant added if needed. Use S.A.E.
90 Hypoid Lubricant (suitable for passenger car duty) in the rear
axle. After the unit is thoroughly broken in (several thousand miles),
Multi-Purpose Gear Lubricant may be added on the responsibility of
the lubricant supplier (no special additives to these lubricants are
required or recommended). Rear axle capacity is 5 pints.
MANIFOLD HEAT CONTROL VALVE-Check for freedom of
movement of manifold heat control valve; if sticking, lubricate bush- ':
ings with graphite in alcohol.
BATTERY - The level of the · electrolyte solution in your battery
should be kept up to but not over the bottom of the vent well. Check
this level at · regular lubrication intervals (more frequently in. ex-
tremely hot weather) . Add DISTILLED WATER to bring the
solution level to bottom of vent well whenever necessary.
