Power
End
Assembly:
Reverse the steps to assemble the power end.
1.
Install new oil, oil seals and gaskets.
Crankshaft End
Play:
When the pump is built, the crankshaft end play is set at 0.001 to 0.005" (0.03 to 0.12 mm).
Only when replacing a crankshaft or a main bearing does this end play need to be reset
to
these limits.
Measure end play by mounting a dial indicator on the power frame and placing the indicator
button on any vertical surface
of
the crankshaft. Pry the crankshaft to one side (Figure
8-41), and then to the other, noting the total travel
of
the dial indicator.
To
change end play,
add or remove shims at the crankshaft frame caps.
Figure
8-41.
