DIFFERENTIAL CARRIER REPAIR (Contd)

ASSEMBLY AND ADJUSTMENT (Contd)

NOTE

Ensure pinion shaft is secured to prevent rotation.

37.

Install dial indicator on carrier (1) and position plunger against tooth of bevel gear (2).

38.

Measure backlash between bevel gear (2) and helical pinion (3). Proper backlash is 0.0050.015 in.

(0.0130.038 cm).

39.

If backlash is correct, go to step 48.

40.

Remove six screws (6), bearing cover (5), and shims (4) from carrier (1). Tie shims (4) to bearing

cover (3).

NOTE

Secure bevel gear with brass drift to prevent rotation of bevel

gear.

41.

Remove two screws (8) and plate (9) from helical pinion shaft (12).

42.

Remove bearing cage (10) from carrier (1) with two puller screws.

NOTE

If backlash is greater than 0.015 in. (0.038 cm), remove a shim

or use a thinner shim.

If backlash is less than 0.005 in. (0.013 cm), add a shim or use

a thicker shim.

Ensure even installation of bearing cage by evenly tightening

screws.

43.

Add or remove shims (11) as necessary.

44.

Align hole in shims (11) with holes in bearing cage (10) and install bearing cage (10) and shim (11)

and two puller screws on carrier (1).

NOTE

Secure bevel gear with brass drift to prevent rotation of bevel

gear.

45.

Install plate (9) on helical pinion shaft (12) with two screws (8). Tighten screws (8) 6077 lb-ft.

(81104 Nm).

46.

Align holes in shims (4) with holes in bearing cover (5), and install shims (4) and bearing cover (5)

on carrier (1) with new lockwashers (7) and screws (6). Tighten screws (6) 6585 lb-ft

(88115 Nm).

47.

Repeat steps 37 and 38.

48.
