NOTE:
Be sure the solenoids are locked in place by pressing down and rotating them.
NOTE:
The counter bore area is where the pump shaft and mating splines pass through the rotor.
NOTE:
The shiny portion of the vane blade is installed outward toward the pump bore ring.
CAUTION:
Be sure the pump bore area is well cleaned. It is a hidden debris trap. Flow from the pump goes into the manual valve circuit, then passes into the EPC circuit. Pump pressure at this point is very high. Any debris not cleaned out here will be pumped through the transaxle on the first operation.
NOTE:
Use the pump shaft to align the pump cover during installation.
