10.4.2 Replacing Power End Bearings & Crankshaft
WARNING:
Disconnect the driver from the pump and insure that suction and
discharge lines are disconnected or blocked and have no pressure
applied.
1. Removal of the fluid cylinder simplifies crankshaft removal on L16 pump models.
2. Remove magnetic pipe plug (32) to
allow all oil to drain from power frame
(1).
3. Remove all rear cover cap screws
(29). Remove the back cover (15)
and back cover gasket (16) from the
power frame.
4. Remove the end cap of each
connecting rod (4) by unscrewing the
two hex nuts that hold each cap to the
connecting rod body. The cap can be
removed from the body by tapping
with a rubber mallet on the cap
screws to remove them and then
tapping on the end cap to loosen it.
Take care to not damage the threads
on the cap screws.
5. Slide the two rod bearing halves (5)
from each connecting rod (4). Note
that these parts sometimes adhere to
the pins (journals) on the crankshaft
(2).
