12. Lubricating the Front Suspension
System
T h e threaded pins and bushings of the front
wheel suspension system require thorough lubri-
cation, with the'weight of the car off the bearings,
to assure adequate lubrication u n t i l the next 1,000
mile lubrication.
W h e n lubricating these parts, therefore, the
front end of the car must be lifted w i t h a jack
placed under the centerroi the front cross mem-
ber, so that the car is supported at the frame, and •
the front suspension system entirely relieved of
weight.
T h e front end of the car must be lifted by the
frame in order to secure thorough lubrication of
the front suspension bearings.
13. Speedometer Drive Cable Lubrication
Disconnect the speedometer drive cable at the
speedometer and apply a few drops of engine o i l
to the upper end of the cable each 6,000 miles.
D o not use tpo much oil, as this may cause faulty
operation of speedometer brought about by an
oversupply of lubricant.
14. Rear Spring Lubrication
T h e rear springs of series 37-50 and 60 cars are
•of advanced design having waxed liners between
each spring leaf as shown in Plate 20, F i g . 9 of
the Rear Suspension Section. These springs
require no lubrication in service. D o not attempt
to lubricate them.
T h e rear springs on all of the other 37-series cars
have grease-packed spring covers which m a y be
lubricated,."if necessary, in the following manner:
1. Disconnect shock absorber links.
2. Raise the rear end of the car w i t h overhead
hoist or chain fall until all weight is taken off rear
springs.
3. Install the clamp (Tool N o . J-595) over one
of the spring covers with the lubricant outlet
fitting entering the hole in the under side of the
cover, and screw the injector tip in u n t i l it has
fully penetrated the inner canvas covers.
4. A p p l y a grease gun filled w i t h graphite
lubricant (G-15) to the connection in the clamp
and force the lubricant into the spring cover.
5. A t the same time, insert a large screw driver
in the end of the spring, cover and pry the second
leaf away from the eye leaf to permit the lubricant
to flow between the leaves.
6. A p p l y lubricant until it seeps out at both
ends of the cover.
If it should seep steadily out at the large end
and not appear at the spring eye end, a clamp
should be applied to the large end to prevent
further flow while the lubricant is being forced to
the spring eye end.
If the lubricant seeps out between the sections
of the cover, the tool has not been inserted through .
the canvas. T h e tool must penetrate the inner
canvas covers.
Caution: D o not let the car down while the injector
tip is inserted, otherwise the tip will be
broken off by the end of the nearest leaf..
7. U p o n removing the clamp, plug the hole .
with one of the • special buttons furnished w i t h
the tool. Install the button by s i m p l y tapping in
place w i t h a light hammer.
15. Clutch Release Bearing Lubrication
T h e c l u t c h release bearing on all 37-series cars,,
except series 37-90, is packed at assembly with
sufficient lubricant to last the life of the part,
and lubrication in service is not required under
ordinary conditions.
In the event of squeaks after a long period- of
use, however, the plug in the clutch release bear-
ing sleeve should be removed, a lubrication fitting
installed, and wheel bearing lubricant (G-12),
applied to the bearing and sleeve sparingly.
Note:- Be sure to reinstall lubrication plug after ,
completing this operation.
T h e c l u t c h release bearing on a l l V - S cars can
be reached after removing the bottom of the c l u t c h
housing. O n V - 1 2 cars, the bearing is accessible
through the hand hole i n the top of the flywheel
housing.
O n the series 37-90 cars, an external lubrication
fitting is provided for lubricating the c l u t c h
release bearing. It is located at the right hand
side of the flywheel housing, and consists of a
plain grease cup w h i c h should be turned down,
refilled with G-12 wheel bearing lubricant, and
turned down a few turns every 6,000 miles.
16. Lubricating Clutch Connection Pilot
Bearing
Whenever the transmission and clutch assembly
on any Cadillac or L a Salle car is removed for
any reason, it is important that the clutch con-
nection pilot bearing should be inspected to make
sure that it is in good condition a n d adequately
lubricated.
This bearing should always be coated with wheel .
bearing lubricant (G-12) if removed from the car
at any time, but too m u c h lubricant should not
be used because of the possibility of grease reach-
ing the clutch plates.
Insufficient lubricant may result in seizing and
turning in the race which would cause rapid wear
on the shaft a n d on the gear teeth in consequence
of the whip.
