in Fig. 15. Maximum allowable end play
is 0.5 mm (0.020 inch). If end play is ex-

8. R&R AND OVERHAUL. Drain
oil from axle housing, then remove outer
drive assemblies and differential yoke
shafts as outlined in previous
paragraph. Disconnect drive shaft. Sup-
port differential housing, then remove
front pivot pin and separate axle hous-
ing assembly from tractor.
To remove differential assembly,
remove mounting cap screws and
separate left axle housing (30-Fig. 16)
from differential housing (14). Remove
differential assembly from housing.
Remove bevel pinion case (6) mounting
cap screws, then withdraw pinion
assembly from differential housing. Re-
tain shims for use in reassembly.
To disassemble differential, remove
carrier bearings (16 and 27) using a

suitable puller. Remove ring gear moun-
ting caps screws and remove ring gear
(26), side gear (21), thrust washer (20)
and bushing (25). Scribe match marks on
pinion gears (24) and side gear (21) so
gears can be reinstalled in their original
positions. Use a punch to remove pinion
shaft dowel pins (19), then withdraw pin-
ion shaft (18) and gears from differential
case.
Place bevel pinion drive gear (11) in a
suitable holding fixture, then remove
nut (1). Press bevel gear shaft out of
bearings and bearing case.
Inspect all gears and bearings for ex-
cessive wear or other damage. Max-
imum allowable operating clearance be-
tween differential side gears (21) and
differential case (17) and ring gear
bushing (25) is 0.4 mm (0.016 inch). Pi-
nion shaft (18) to pinion gear bushing
(23) clearance should not exceed 0.3 mm
(0.012 inch). Renew all parts as needed.
Ring gear and pinion are available only
as a matched set.
Reassemble differential making cer-
tain match marks made during
disassembly are aligned. Check side
gear to pinion gear backlash using a dial
indicator as shown in Fig. 17. Backlash
should not exceed 0.4 mm (0.016 inch).

exceed 0.5 mm (0.020 inch). Use a dial indicator
as shown to measure end piay.
