As normal wear occurs and there is excessive "play" between the
wedge and beam, adjust the bolts on the side of the wedge assembly
to eliminate excess space between the wedge and the beam.
1. Loosen the jam nuts on the two adjustment bolts on the side of the
wedge. See Figure 16.

slowly (approximately 1.5 turns) until the wedge assembly will slide
on the beam.
3. Re-tighten the jam nuts securely against the side of the wedge to
secure the adjustment bolts in this position.
GIb ADJuSTmENT
Periodically remove and replace the "gibs" (spacers) between the
wedge assembly and the back plate.

1. Loosen the lock nuts under each back plate and slide the gibs out.
See Figure 16.

FLExIbLE pump CoupLER
The flexible pump coupler is a nylon "spider" insert, located between
the pump and the engine shaft. Over time, the coupler will harden and
deteriorate. If you detect vibration or noise coming from the area be-
tween the engine and the pump contact an authorized service dealer.
If the coupler fails completely, you will experience a loss of power.
TIRES
The maximum pressure for the tires is 30 psi. Do not exceed the
manufacturer's recommended psi under any circumstances. Maintain
equal pressure on all tires.
Excessive pressure when seating beads may cause the tire/rim
assembly to burst with force sufficient to cause serious injury. Refer to
sidewall of the tire for the recommended pressure.
