CLUTCH CONTROL
The clutch is self-adjusting and requires no
attention other than lubrication, as outlined on
page 21, and occasionally checking the clutch
pedal to floorboard clearance to prevent the
clutch pedal from "riding" the floorboard.
Figure 44
Clutch Pedal Adjustment
It is essential that one and one-half
inches clearance be maintained between
the pedal shank and floorboard when the
clutch is engaged, as shown in Figure 44.
To adjust for proper clearance, loosen lock
nut (A), Figure 45, remove clevis pin (C) and
turn yoke (B) to shorten or lengthen the rod, as
necessary.
Replace clevis pin (C) and cotter pin.
Tighten lock nut (A) securely.
TRANSMISSION
A quick synchronizing transmission, Figure
46, incorporating helical gears to give a silent
second gear and involute spline mainshaft and
countershaft to provide easy shifting, is used in
the 1938 Hudson Terraplane.
All gears are made of nickel chrome molyb-
denum alloy steel, carefully heat-treated for
strength and case-hardened to resist wear and
provide long life. Through the use of this spe-
cial alloy steel the use of heavy parts is unnec-
essary, contributing greatly to ease and
rapidity of shifting.
The mainshaft drive gear is supported by two annular ball bearings, as is the rear end of the
mainshaft. The front of the mainshaft is mounted in needle roller bearings instead of in a bronze
bushing, which is conventional practice. Steel ball bearings at this point absorb the mainshaft
thrust load.
The countershaft is carried in generous sized steel backed babbitt bearings.
