DRIVE HOUSING, CONNECTING ROD & CRANKSHAFT REPLACEMENT
14. Screw the displacement pump about 3/4 of the way
into the drive housing (73). Hold the pin (43) up to the
pin hole in the connecting rod assembly (70) and
continue screwing in the pump until the pin slides
easily into the hole. Back off the pump until the top
threads of the pump cylinder are flush with the face of
the drive housing and the outlet nipple (39) is facing
back. Push the retaining spring (42) into the groove
all the way around the connecting rod. Tighten the
locknut (41) very tight – about 70 ft-lb (95 N.m) – with
a 1-3/4 in. open end wrench and a light hammer. See
Fig 33–1 and 33–2.
WARNING
Be sure the retaining spring (42) is firmly in the
groove all the way around, to prevent the pin (43)
from working loose due to vibration. See Fig 33–1.
If the pin works loose, it or other parts could break off
due to the force of the pump action. These parts
could be projected through the air and result in seri-
ous bodily injury or property damage, including dam-
age to the pump connecting rod or bearing housing.
15. Reinstall the remaining parts.
