(6)

Install the drive pinion (73) in the differential carrier assembly (9) with pinion through inner and

outer bearing cups (78 and 79). Place the carrier in the press with the legs of the carrier towards

bottom of press and place supports under carrier so carrier is level. Place a wooden support under

head of drive pinion (73) so that inner bearing cone (79) on pinion shaft (73) contacts inner bearing

cup (79) in carrier. Use a press and sleeve to install outer bearing cone (78) on pinion. Apply two

tons of pressure to ensure bearing cone (78) is correctly installed.

(7)

Refer to paragraph (41) and adjust bearing preload and gear tooth contact pattern.

(8)

After adjusting bearing preload and gear tooth pattern, remove outer bearing cone (76) from drive

pinion (73). Turn carrier over to bring the legs of the differential carrier assembly (9) to the top of

the press. Be sure carrier is level.

(9)

Put the helical gear (77) over the pinion bore with splines in bore of gear towards front of

differential carrier assembly (9). Put the large spacer (75) on top of helical gear with spacer (75)

towards rear bearing cup (79).

(10)

Install the drive pinion (73) in the helical gear (77) with spines on pinion engaging splines in helical

gear (77).

(11)

Use a protector on the head of the drive pinion (73) and press drive pinion (73) into helical gear

(77) so that inner bearing cone (81) touches bearing cup (79).
