Removal
1. Drain the oil from the power end as out-
lined in “Changing the Power End Oil” on
page 73.
2. Once drained, remove the capscrews,
washers and lockwashers from the back
plate (Figure 154). Remove the plate, belt
guard and gasket. If the gasket is stuck to
the frame, it can remain.
3. Remove the rod cap capscrews (Figure
155) from each rod journal. Rotate the
pump by pulling on the belts (Figure 156),
to gain access to the capscrews as need-
ed.
4. Once the capscrews are removed, remove
each rod cap from the crankshaft. Ob-
serve the stamp marks on the top of the
cap and rod for correct assembly.
5. To check the bearing life, proceed to In-
spection. If the bearings are known to be
worn, continue to the following step.
