bent
castings.
6. Check condition of O-ring on volute. Check for nicks,
cracks and gauges. Defective O-rings will cause
poor priming and loss of pump performance.
7. Remove impeller with rubber mallet. Hit one of the
blades in the counter-clockwise position. It is best to
not block the engine for this procedure. Only use a
fl ywheel strap when it does become necessary.
8. Slowly turn the impeller off the crankshaft. Watch
that the impeller does not drop off quickly when
reaching the end of the threads. Use two hands if
necessary. Watch for loose parts such as the shims.
