against thrust plate (11). Install matched driven gear
(13) hub into its bearing (9) so that the three teeth
marked at 'Disassembly' will mesh. See Fig. 26.
8. Coat new seals (14 & 16) with grease and insert
them into their grooves in both sides of gear housings
(15, 22 & 27). See Fig. 27.
9. Slide gear housing (15) over gears (12 & 13) and,
with match marks made at 'Disassembly' aligned, tap
gear housing (15) with a soft hammer until it rests
snugly against shaft end cover (6). See Fig. 28. If a
new gear housing is used, make sure the large oil
port will be toward the inlet, and the small port toward
the outlet side of the pump assembly. Be sure seal
(14) is not pinched or dislodged. Coat gears (12 & 13)
with hydraulic fluid for initial lubrication when the
pump is started.
10. With match marks aligned, position bearing
carrier (18) on gear housing (15) so that bearings (9)
will receive the journals of the drive and driven gears
(12 & 13). Tap bearing carrier (18) down tight with a
soft hammer. See Fig. 29.
Note: The drain hole plug (19) must be on the inlet
side of the pump.
11. Insert connecting shaft (17) into the spline of
driveshaft and gear (12). See Fig. 30.
12. Insert the matched set of drive and driven gears
(20 & 21) into their respective bores of bearings (9) in
bearing carrier (18) so that the three teeth marked at
'Disassembly' will mesh. See Fig. 31. Push the gears
down tightly against thrust plate (11).
13. Repeat Steps 9 through 12 to assemble gear
housing (22), bearing carrier (24), connecting shaft
(23), drive gear (25) and driven gear (26).
14. Slide gear housing (27) over gears (25 & 26) and,
