12. Remove the hex head cap screws
(28), bearing housings (12 and 36),
and shims (13) from both sides of the
pump. Count and record the shims
on each side to facilitate assembly.
The gaskets (14) may adhere to the
power frame surface and can be left
in place if they are not damaged. For
pump models that use o-ring seals it
is recommended that the o-rings be
replaced. The bearing cups (23) will
remain in the bearing housing. On
pumps with no pinion shaft (some HD
or HV models) there will be an oil seal
(19) that will remain attached to one housing. It may be necessary to tap on the
housing with a rubber mallet to free it from the power frame after the hex head
cap screws have been removed.
13. To remove the crankshaft (2) on
pump models with no pinion shaft
(some HD and HV), carefully move it
through one side of the bearing
housing opening in the power frame
(1). The throws may have to be
rotated as the crank is removed to
clear the connecting rods. The
crankshaft should be handled
carefully to prevent the critical bearing
surfaces from being scratched or
damaged.
14. To remove the crankshaft on
industrial pump models with a pinion
shaft, work the crankshaft to the left
when viewing from the rear opening of
the power frame. The bearing cone
(22) will be partially out of the bearing
housing opening. The throws or
journals may have to be rotated as
the crank is removed to clear the
connecting rods. On L16 pumps the
throw to the right of the gear (when
viewing from the real opening in the
power frame) must be toward the
opening. Slip the crankshaft end on
the right out the back of the power
frame and remove. The crankshaft should be handled carefully to prevent the
critical bearing surfaces from being scratched or damaged.
