Chassis Grease
Lubricant conforming to the specifications for Chassis Greaseis
recommended for all chassis points fitted with grease gun connections.
Do not use ordinary cup grease, as such greases are
not effective enough to lubricate satisfactorily over the 1000-
mile interval.
camshaft. The oil circulated bv the pump lubricates the main
and connecting rod hearings, the camshaft bearings, thecvlinder
walls, pistons and piston pins, the front end chains, the valve
mechanism and the fan.
Wheel Bearing Grease
Greases approved under the specifications for Wheel Hearing
Grease are suitable for lubricating the wheel bearings and the
clutch release bearing.
This grease is not recommended for chassis lubrication, as
Chassis Grease is much more effective. Furthermore, Chassis
Grease or ordinary cup grease should not be used in the wheel
bearings as such lubricants do not have a sufficiently high melting
point to render satisfactorv service.
Water Pump Grease
A water-resistant calcium soap grease is recommended for use
in the water pump grease cup. Only greases that meet the
specifications for Water Pump Grease should be used; other
greases will be dissolved into the cooling system liquid.
The owner of a Cadillac car is urged to have his car put on
schedule lubrication at an authorized Cadillac-La Salle service
station; in this way he is assured of having the proper lubricants
used for all lubricating points at the proper mileage intervals.
Engine Lubrication
The supply of oil is carried in the cast aluminum oil pan that
covers the bottom of the crankcase. The oil is circulated by a
gear pump inside of the crankcase. The pump is driven by a
vertical shaft, which is, in turn, driven by a spiral gear on the

plug and other lubrication features.
There are a few points on the engine that are not taken care
of in the pressure system. These are the starter, generator and
distributor oil cups and the water pump. Lubricating instructions
for these points are given in the lubrication chart.
Oil Level
The normal capacity of the oil pan is eight quarts, which fills
it to the level of the screen in the pan. When the oil pan contains
this amount, the oil level indicator on the right-hand side
of the engine (Fig. 20) indicates "Full." As the oil level
descends, the indicator indicates "Fill" and then "MT" (Empty).
Oil should be added as soon as the indicator ball has dropped to
