TROUBLESHOOTING CLUTCH PROBLEMS
FIGURE 18. THROW OUT BEARING
Step 4. To ensure that the clutch disc is separating, check
the pressure on the clutch disc.
I WARNING I
Do not have the engine running.
It the clutch does not disengage after following the proper
adjustment procedures or you cannot shift from neutral to
any gear without the gears grinding, the following
conditions could exist.
1. The milled slot In the rear pressure plate is not centered
and it is binding on the roll pin. Replace the rear
pressure plate.
2. If either of the pressure plates are warped, the clutch
will not separate and they should be replaced.
3. If any weld splash is on either pressure plate, it will
cause the disc to hang up and the clutch will not
disengage. Remove the splash or replace the pressure
plates.
4. When the holes are not drilled properly in the fiber
clutch disc it will hang up on the drive pins and will not
separate. Replace the fiber disc.
5. Rust on the center shaft of the clutch can cause the
spring guides under the small spring to bind. See Figure
19. Remove the rust from the shaft and lubricate with a
thin film of oil.
Depress the clutch pedal with your left hand
and try to rotate the small spring located
between the pressure plate and the throwout
yoke with your right hand. See Figure 19. You
should be able to rotate this spring by hand. If
it does not repeat steps 2 and 3.

BRAKE ADJUSTMENT
To adjust the brake, tighten the locknut on the disc brake
located on*the left hand side of the transaxle. The brake
should be tightened enough to stop the tractor when the
pedal is depressed but still allow the disc to turn free
between the brake pads when the pedal is released. See
Figure 20.
