Clutch Pedal Adjustment
The clutch is self-adjusting; however, it is necessary to adjust the clutch
pedal rod to prevent the pedal from "riding" the floor board. To adjust,
loosen lock nut (A), Figure 8, remove clevis pin (C) and turn yoke (B) to
shorten or lengthen the rod, as necessary, so that the pedal shank can be held
in a position one and one-half inches from the floor board when the clutch is
engaged. Replace the clevis pin (C) and cotter pin. Tighten lock nut (A). The
pedal clearance should be checked frequently as a lack of clearance will
cause clutch slippage.
On cars equipped with Automatic Clutch Control pull backward on the
control unit cable—on left side of engine—while the accelerator pedal is
depressed. When the cable is in its extreme rearward position there should
be approximately %g
"
clearance between the hack of the slot in the cable
yoke and the clevis pin which attaches it to the operating lever.
TRANSMISSION
The transmission is of the quick synchronizing type, incorporating helical
gears to give a silent second speed. Unusual silence is obtained in all forward
speeds by throwing the reverse idlers out of mesh so that they do not revolve
except when in actual use. Through the use of steel alloyed with nickel,
chrome and molybdenum in gears which are heat-treated for strength and
case-hardened to resist wear, long life is assured. The use of these special
alloys also makes extremely heavy parts unnecessary, contributing greatly to
ease and rapidity of shifting.
The main drive gear and main shaft are supported by two heavy duty,
annular thrust ball bearings, one annular ball bearing and thirty needle
bearing rollers. The end thrust between these parts is taken by seven ball
bearings running in races machined in the ends of the shafts.
The countershaft is carried on steel backed, babbitt bearings.
Lubrication
The lubricant used must be able to
withstand the pressure developed
between the gear teeth and also flow
freely into the small clearances of
the bearings. These qualities can be
obtained in S.A.E. 110 transmission
gear oil for summer and S.A.E. 80
(zero pour test) transmission gear oil
in winter.
The transmission should be filled
with lubricant to the level of the
filler plug (A), Figure 9, at all times.
Drain the lubricant with season by removing plug (B) and replacing with
three pounds (or pints) of fresh oil of the proper specifications.
