40 LUBRICATION
Every 4,000 miles, while the front wheels are removed for lubricating,
the brake operating trunnions inside the front wheel brake drums should
also be lubricated as follows:
Remove the screw plug "A", Fig. 19,
(shown at 15 and 29 in Fig. 18) and replace
it with the grease gun connection furnished
in the tool kit. Attach the grease gun
and inject grease just until it begins to
appear around the trunnion bearing inside
the drum. Do not inject too much grease.
Remove the grease gun connection and
replace the screw plug. Before replacing
the wheel be sure and wipe off any grease
appearing around the trunnion bearing.
Do not inject any grease at "A" except
when the wheel is off and the application
of too much grease can be positively
avoided. Pig. 19. Front Wheel Brake
Lubricating Plug.
Clean Engine Lubricating System
At the end of every 4,000 miles of travel clean the engine lubricating
system and the oil pan and screen. (See under "Replace Engine Oil" page
33 and "Replace Engine Oil Frequently During Cold Weather," page 34.)
Horn: 13
The horn is lubricated when assembled and does not require further
lubrication but the commutator of the horn should be inspected every 4,000
miles and cleaned if necessary. To do this remove the motor shell from the
horn. (On cars with the horn mounted on the fanshaft housing, the horn
with bracket must be removed from the engine before the motor shell can
be removed from the horn). If the commutator appears to be dirty clean
it with a dry cloth. This should be done with the horn motor running so
that the commutator will be cleaned on all sides. Do not attempt to
polish the commutator or brushes with oil or vaseline. These parts are
designed to run dry.
Replace Transmission Lubricant: 20
At the end of every 4,000 miles of travel remove the drain plug from the
under side of the transmission case and drain out all of the lubricant. Refill
with two quarts of suitable lubricant. Cadillac Rear Axle and Transmis-
sion lubricant is recommended. The filler is shown at "20," Fig. 18.
Replace Rear Axle Lubricant: 17
At the end of every 5,000 miles of travel remove the drain plug from

the axle and drain out all of the lubricant. Refill with 5 quarts of suitable
lubricant. Cadillac Rear Axle and Transmission Lubricant is recommended.
The filler is shown at "17," Fig. 18.
ADDITIONAL
In addition to the places specially mentioned, note carefully and oil
all of the small connections and joints throughout the car, such as the various
brake rod connections and joints in the brake mechanism.
Remember that wherever one part moves in contact with another
wear will be reduced to the minimum by lubrication.
