7. Be careful when disassembling. The needle bearings
in the body assembly (Item 15) may be of the loose
grease retained type. Pack these with general purpose
grease to retain them for reassembly. It is recommended
NOT to remove the bearing races from the flange as-
sembly.
8. Remove and discard the oil seal and seal rings
(Items 17 and 23) as the pump is disassembled.

scoring, nicks, etc. Check the bushings in the plate
assemblies (Items 22, 26 and 28) and cover assembly
(Item 31) for excessive wear or scoring. Replace the
assemblies as necessary. The bushings are not serv-
iceable.
10. Stone gears if plate surfaces appear scored. Re-
place gears as sets if necessary. Oil the inside of gear
plates (Items 14, 25 and 30) and insert gear sets,
maintaining the original timing and locations.
11. Assemble pump sections starting at the body as-
sembly (Item 15). Install woodruff keys (Item 19) and
align keyways in gears as they are installed over the
shafts. Apply grease to new seal rings (Item 23) before
installing.
12. After pump has been assembled, tighten locknuts
by hand. Rotate the drive shaft to check for binding.
Protect the shaft if using a pliers.

on pump shaft or apply tape on the shaft.

ter of new oil seal. Carefully install a new oil seal.
