SERVICE & ADJUSTMENTS
WARNING
Do not at any time make any adjustments without first stopping
the engine, disconnecting spark plug wire and grounding it against
the engine. Always wear safety glasses during operation 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.
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
• Before each use check to see if the 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.
