(10) Refer to figure 3-50. Press the gear (1) onto the shaft (2) and beyond the ball slot.

Figure 3-50. Fuel Pump, Assembly.

(13) Lubricate the driven gear shaft (5) with light grease (item 11, Appendix C) and install.

CAUTION

Use care that sealant is not squeezed into the gear compartment, otherwise damage to the gears

and shaft may result.

(14) Apply a thin coat of sealant (item 21, Appendix C) to the cover mating surface. Install cover (6)

and secure with eight lockwashers (7) and eight bolts (8).

NOTE

The coating of sealant must be extremely thin since the pump clearances have been set up on

the basis of metal-to-metal contact. Too much sealant could increase the clearances and affect

the efficiency of the pump.

(15) Install valve (9), pin (10), spring (11), gasket (12), and plug (13). Torque plug (13) to 18-22 lb-ft

(24-30 Nm).

(16) Turn pump shaft by hand to ensure the gears rotate freely.
