L U B R I C A T I O N
Note: A grease cup is provided for drive shaft
bearing lubrication on V-8 engines, and a
pressure fitting on V-12 and V-16 engines.
O n a l l 37-series cars, except the V-16, a felt
wick is located in the center of the timer cam to
provide a means of lubrication for the distributor
advance mechanism. T h e wick is accessible after
removal of the distributor rotor, and engine oil
should be applied to the wick every 3,000 miles, or
at least, every time the distributor cap is removed
for service attention.
A n oil cup is provided for this purpose on series
37-90 distributors, and on these cars, a few drops
of engine oil should be applied every 1,000 miles.
The application of a slight amount of petrola-
t u m to the timer cam whenever the distributor is
disassembled is also beneficial i n preventing
excessive wear of the rubbing blocks.
7. Universal Joint and Propeller Shaft Spline
Joint Lubrication
The universal joints on all 37-series cars, except
the V-16, are packed at assembly and do not
require lubrication in service unless disassembled.
The propeller shaft spline j o i n t on all 37-series
cars, however, must be lubricated with chassis
lubricant every 1000 miles-.
On all 37-series cars, except the V - 1 6 , lubrica-
tion of the splines is provided for b y a lubrication
fitting in the propeller shaft at the spline joint.
O n series 37-90 cars, both the universal joint
cross and the spline joint are provided w i t h screw
plugs for lubrication fittings. A pressure fitting
should be substituted for the screw plug i n the
spline j o i n t and chassis lubricant applied every
1000 miles. T h e screw plug in the universal j o i n t
should, likewise, be removed and chassis lubricant
applied every 6,000 miles.
A l w a y s be sure to replace the screw plug after
performing these operations.
8. Steering Gear Lubrication
Special steering gear lubricant, meeting the
S-200 specifications, is' required for use in the
steering gears of a l l 37-series cars. T h e lubricant
level should be inspected every 30.00 miles and
additional lubricant added to bring the level to
the filler plug opening. A s this lubricant is suitable
for a l l season use, there is no necessity for draining
and replacing, except in the event of steering gear
disassembly.
9. "Grease Gun" Connections and Lubrica-
tion
L u b r i c a t i o n fittings for use of a grease gun are
used whenever practical on the engine and chassis
of all 37-series cars.
A l l of the points on the car that are provided
w i t h grease gun connections should be lubricated
every 1000 miles.
The location of these points may be found by
inspection or by looking at a Cadillac-LaSalle
L u b r i c a t i o n C h a r t . T h e y include such points as
the following: knuckle pins, suspension arm con-
nections, steering connections, propeller shaft
spline j o i n t , rear spring shackles, shock absorber
links, rear spring bolts on series 37-50 and 60
cars, distributor drive shaft on series 37-85 and
90 cars, pedal shaft on series 37-65, 70, 75, 85
and 90 cars, brake shafts, parking brake cables and
stabilizer linkage on series 37-90 cars, etc.
10. "Oil Can" Lubrication
There are a number of points on the engine and
chassis which, although not provided w i t h a
lubrication fitting, w i l l operate more freely if
given regular oiling.
M o s t important of these points are the hand
brake cables, levers and brackets, a n d the c l u t c h
release connections, and pedal felts and shaft on
series 37-50 and 60. Engine oil should be applied
to these points w i t h an oil can every 1,000 miles
to assure free operation.
T h e throttle and choke connections on the dash
and the engine, including the rocker shafts for
these connections on series 37-85 and 90 should
also be lubricated with a few drops of engine oil
every 1000 nilles.
11. Wheel Bearing Lubrication •
The front wheel bearings on a l l series cars
require repacking with wheel bearing grease and
readjustment every 6,000 miles. In iubricating
these bearings, always use grease meeting the
(G-12) specifications. The bearings should be
liberally coated w i t h grease, but there is no
necessity for filling the hub completely. It is only-
necessary to see that all parts of the bearings are
lubricated.
In adjusting the front wheel bearings, first make
sure that the wheel is all-the way on the spindle.
•Then tighten the adjusting n u t securely, using a
wrench with a handle 8 or 9 inches long, at the
same time rotating the wheel to seat a l l parts.
After a thorough tightening, back off the nut. 1/12
turn (Yi flat). If the cotter key cannot be
installed in this position loosen the adjusting nut
u n t i l it can be installed.
T h e rear wheel bearings on a l l series cars are of
the self-lubricating type and require no adjust-
ment. These bearings are packed with lubricant
and permanently sealed at assembly. Since this
lubricant is intended to last for the life of the
bearings, no provision is made on the car for
lubricating them. N o attempt should be made to
remove these bearings for lubricating purposes.
