Removal
1. Drain the oil from the power end as outlined in
“Changing the Power End Oil” on page 53.
2. Once drained, remove the capscrews, wash-
ers and lockwashers from the back plate
(Figure 108). 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 109)
from each rod journal. Rotate the pump by
pulling on the belts (Figure 110), to gain
access to the capscrews as needed.
4. Once the capscrews are removed, remove
each rod cap from the crankshaft. Observe the
stamp marks on the top of the cap and rod for
correct assembly.
5. To check the bearing life, proceed to Inspec-
tion. If the bearings are known to be worn,
continue to the following step.
