  2. Clamp shaft in soft jawed vise and install new retaining ring on splined end of shaft by prying ring open and sliding it down over shaft until it seats itself in ring groove. Insert drive shaft with thrust plate and rotor into housing. Make sure shaft it properly seated. Place pump housing in vise, hub down, using flat on hub for clamping surface.
  3. Install dowel pins through thrust plate into pump housing. Install cam ring on dowel pins with rotation arrow toward rear of pump housing and pointing in direction of pump rotation. Install vanes in slots of rotor, with radius edges toward outside of rotor, so they ride on cam ring. Install pressure plate on dowel pins with ported face toward cam ring. Install plate so that narrow slots in plate engage dowel pins. Install pressure plate spring.
  4. Lubricate outside diameter of end plate with vaseline and install end plate in pump housing. Place pump housing in arbor press, depress end plate below retaining ring groove, and install end plate retaining ring.
