CLUTCH
SPECIFICATIONS
CONSTRUCTION
The clutch for models 1C and 2C is a single dry
disc type. No adjustment for wear is provided in the
clutch assembly. The adjustment to compensate for
lining wear is provided by the clutch pedal linkage.
Individual clutch release lever adjustments are made
when the clutch is assembled but should never be
disturbed except after disassembly for replacement
of worn parts. A ball type clutch release bearing,
pre-lubricated during manufacturing, is utilized and
needs no additional lubrication. A steel clutch cover
is bolted to the flywheel and contains the pressure
plate, clutch pressure springs , clutch release levers
and clutch drive plate.
OPERATION
The clutch plate has molded woven asbes-
tos facings riveted t o both sides. Six dampen-
ing springs absorb shocks and cushions torque
loads.
Pressure on operation of the clutch pedal
moves the release bearing and collar assembly
toward the release levers (5) which are
pivoted on pins (8) in the eye bolts (9), adjust-
able t o control release lever heights. Pivot
pins float in the eye bolt bores to permit
release lever movement. The outer ends of t he
release levers engage the pressure plate lugs
through fulcrums (7) providing knife edged
contacts between the levers and lugs, Figure
6.
CLUTCH PEDAL ADJUSTMENT
Full clutch disengagement must be provided to prevent
gear clashing when shifting and to prevent the clutch
pedal from riding against the floor boards. The clutch
pedal clearance should be from 3/4" t o 1-1/4", Figure
1.
FIGURE 1
To adjust the clutch pedal to maintain proper clearance
proceed as follows:
1. Loosen lock nut (3) Figure 1 on clutch adjusting link
(2).
2. Back off o r tighten adjusting nut (4) to in crease or
decrease the clearance as required.
