11. Invert the housing and insert the rotating piston
block assembly, 1, into the housing.
NOTE: Piston shoes must contact the cam plate. Be
sure all parts are in their proper position before pro-
ceeding.
NOTE: If the rotating group assembly will not easily
slide over the splined shaft, DO NOT FORCE. One
or more of the three loading pins may be out of their
groove or the pin head is not seated properly be-
tween the washer and block. Forcing the rotating
group may cause pin failure and early transmission
failure.
IMPORTANT: Make sure all mating surfaces are well
lubricated with SAE 10W-30 motor oil to insure prop-
er lubrication for start-up.
12. Install a new bearing in the back plate if required.
Install the bearing with the numbers facing the
center of the pump assembly, pressing the bear-
ing down to 3/32" above the plate at 1. The bear-
ing is a pilot for the bearing plate, 2, during as-
sembly.
NOTE: When installing bearings in the plate or hous-
ing, be careful not to damage the outer bearing race.
If the outer race is damaged, this could cause an ear-
ly bearing and shaft failure.
13. Lubricate the replaceable valve plate, 1, and
place the steel side to the back plate aligning
small groove with pin, 2. The brass side of the
valve plate, 3, should be next to the piston block
when assembled.
