5. Place the driven shaft and gear assembly in the pump body.
CAUTION
The driven gear must be centered on the shaft to give proper end clearance. Also, the chamfered end of
the gear teeth of the production gear must face the pump body. If a service replacement gear with a slot
is used, the slot must face toward the pump cover.
6. Lubricate the gears and shafts with clean engine oil.
7. Apply a thin coat of quality sealant on the face of the pump cover outside of the gear pocket area. Then
place the cover against the pump body with the two dowel pins in the cover entering the holes in the pump
body. The cover can be installed in only one position over the two shafts.
