Connecting Rod and Cam Bearing, the
Connecting Rod should be replaced. This can be
determined using a feeler gauge. The Cam
Bearing should also be inspected as a bad cam
bearing is the most common cause of a damaged
Connecting Rod. A worn Connecting Rod results
in low volume, low pressure, a hammering sound
and the pump running hot (See Figure 8).
5. Inspect Crankshaft Assembly for general wear.
Rotate Cam Bearing and Main Bearings to check
for roughness due to moisture contamination or
lack of grease. If main bearings do not turn
smoothly or appear to be damaged, they should
be replaced. If cam bearing is damaged, a new
Crankshaft Sub-assembly should be installed and
the connecting rod inspected for wear (See Figure
8).
NOTE: Always use new O-rings, Cups, Seal Rings,
Support Rings, Guides, Washers, and Piston Cap
Screws. If new Valves are needed, always replace
the complete set of four.
