Figure 5. Fixture Dimensions, Drive Gear And Shaft Installation

Center the inboard spacer sleeve (3) on the inner
bearing race. Center the drive gear (25) in the gear­
box housing and engage the teeth of the pinion
shaft. Rest the gear on the spacer sleeve, taking
care to align the keyway in the drive gear with the
slot in the spacer.

Install the drive gear key (29) in the shaft keyway.
Align the key with the keyway in the drive gear and
the slot in the spacer, and press the shaft through
the drive gear, spacer sleeve and bearing until the
shaft shoulder seats firmly against the inner race of
the bearing.

Slide the outboard spacer sleeve (3A) onto the
drive shaft, aligning the slot in the spacer with the
shaft key. Press the outboard drive shaft bearing
(14) onto the shaft and into the gearbox housing
until fully seated against the shaft shoulder. The
outboard bearing should not project more than
.129 inch (3,28 mm) from the gearbox housing.

When installing the bearings onto the
shafts, never press or hit against the outer
race, balls, or ball cage. Press only on the
inner race.

Apply a light coating of oil to the lip of the oil seal
(18), and press it into the bearing cover with the lip
positioned as shown in Figure 1. Replace the bear­
ing cover gasket (6), and secure the bearing cover
(13) to the gearbox housing using the hardware
(10 and 11). Be careful not to damage the oil seal
lip on the shaft keyway.

Make sure gasket remains in position and
does not become sandwiched between
pinion shaft bearing and bearing cover.

Replace the cover plate gasket (30), and secure
the cover plate (26) to the gearbox housing with the
capscrews (27).

Replace the oil sump gasket (19), and secure the
oil sump (20) to the gearbox housing with the cap­
screws (21 and 22).

Install the slinger ring (15) and the drive shaft key
(16) on the drive shaft.

Refer to PUMP AND SEAL REASSEMBLY and in­
stall the remaining pump components. After the
pump components are installed, lubricate the
gearbox as indicated in LUBRICATION.

The seal assembly is lubricated by the medium be­
ing pumped, and no additional lubrication is re­
quired.

Gearbox

Before operation, remove the shipping
plug from the street elbow (9) and replace
with the reducing bushing (8) and air vent
