CONSTRUCTION
All Hudson cars except those equipped with Hy-
dra-Matic Drive use a single plate, cork insert, oil
cushioned type clutch.
Details of the clutch may be seen in Figure 3.
Engagement and disengagement of the clutch is
controlled by the clutch foot pedal which is connected
by linkage to the shifter yoke (16). When the clutch
pedal is depressed, the yoke moves forward carrying
with it the throwout bearing (13) which bears against
the 3 throwout fingers (3) which react against the
retainers (5) to move the pressure plate away from the
driving plate and flywheel against the pressure of the
engaging springs (7). This action disconnects the driv-
ing plate (1) and drive gear (15) from the flywheel.
CLUTCH PEDAL ADJUSTMENT
To assure full disengagement of the clutch to
prevent clashing when shifting gears and also to pre-
vent the clutch pedal from riding against the floor
board, 1-1/2" clearance must be maintained between
the floor board and rear face of pedal, Figure 2.
This can be adjusted by loosening lock nut (A),
Figure 3, removing cotter pin and clevis pin (C) and
turning yoke (B) to increase or decrease the clearance
as required. Replace clevis pin and cotter pin and
tighten lock nut securely.
