DIFFERENTIAL CARRIER ASSEMBLY - CONTINUED

Assemble the Shift Unit, Fork, and Shaft.

NOTE

Before installing the shift shaft into the helical gear cover and shift fork, inspect and remove any rough spots

or burrs by polishing the shaft with fine emery cloth.

(1)

Install the shift shaft (46) partially through its bore in the shift unit opening of the helical gear cover (17).

Install the short end of shaft first (Measure from the roll pin hole to shaft ends to determine short end). Use

a rawhide mallet to tap the shaft through.

SHAFT DIRECTION

402-688

(2)

Position the shift fork (47) to the inside front of the helical gear cover (17), alining its shaft bore with the

bore in the cover. The long boss of the fork with the drilled roll pin hole must be facing toward the back.

(3)

Holding the shift fork (47) in position, continue to tap the shift shaft (46) through the gear cover (17) and

fork. Tap shaft in enough to support the fork.

(4)

Install the shift fork return spring (49) between the fork (47) and rear shaft bore in the gear cover (17).

Make sure inner diameter of spring coils are aligned with the shaft bores of the fork and gear cover.

(5)

Continue to tap the shift shaft (45) into position with the rawhide mallet.

NOTE

As the shaft is installed, make sure the roll pin holes of the fork and shaft are aligned. Rotate the shaft if nec-

essary to align holes.

(6)

Assemble the roll pin (48) through the holes in the fork (47) boss and shaft (46). Use a small drift and ham-

mer.
