TRANSMISSION REPAIR (Contd)
REAR HOUSING AND OUTPUT SHAFT ASSEMBLY
NOTE
Place inner bearing races and tapered-roller bearing in a 275 F
(135 C) oven for 30 minutes immediately prior to installation.
1.
Install new output shaft oil seal (5) on rear housing (4).
2.
Install heated tapered-roller bearing races (1), (2), and (3) on rear housing (4).
3.
Check preset position of output gear (7) on output shaft (6) before assembly as follows:
a. Measure and record distance from groove of output shaft (6) to shoulder on output shaft (6) at
small end of taper (measurement A, as shown).
b. Place output gear (7) on output shaft (6) and install on output shaft (6) taper with 100200 lb
(4591 kg) of force.
c. Measure and record distance from rear of output shaft (6) to rear face of output gear (7)
(measurement B, as shown).
d. Subtract distance B from distance A to find preset position of output gear (7). This dimension
must be between 0.0640.096 in. (0.1640.244 cm). Replace output gear (7) or output shaft (6) if
not within limits.
4.
Remove output gear (7) from output shaft (6). Apply light coat of grease to oil seal area of output
shaft (6) and install output shaft (6) on rear housing (4) through output shaft oil seal (5) and tapered-
roller bearing race (2).
5.
Position rear housing (4) and output shaft (6) on hydraulic press with output shaft flange (8) resting
on press table. Install heated tapered-roller bearing (9) on output shaft (6) and, using bearing installer
tool TD-300422, install bearing (9) on output shaft (6).
