WARNING: Do not at any time make any adjust-
ments without first stopping engine, disconnecting
spark plug wire, and grounding it against the
engine. Always wear safety glasses during opera-
tion or while performing any adjustments or repairs.
Wedge Assembly Adjustment
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 5-1.
2. Turn the adjustment bolts in until snug and then back them off
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.
SERVICE & ADJUSTMENTS
Gib
Lock Nut
Gib Adjustment
Periodically remove and replace the "gibs" (spacers) between the
wedge assembly and the back plate.
NOTE: The gibs may be rotated and/or turned over for even wear.
1. Loosen the lock nuts under each back plate and slide the gibs out.
See Figure 5-1.
2. Turn or replace the gibs.
3. Reassemble the back plate and secure with the lock nuts.
4. Readjust the bolts on the side of the wedge assembly.
Hose Clamps
• Check, before each use, if hose clamps on the suction hose
(attached to the side of the pump) are tight. Check the hose clamps
on the return hose at least once a season.
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.
Replace the coupler if you detect vibration or noise coming from the
area between the engine and the pump. If the coupler fails completely,
you will experience a loss of power.
IMPORTANT: Never hit the engine shaft in any manner, as a blow will
cause permanent damage to the engine.
