POWER TAKEOFF
LEAKS OIL
CAUTION
• When replacing gaskets between
power takeoff and transmission
housing, replace with exact
number of gaskets removed.
Failure to use the correct number
of new gaskets will affect power
takeoff to transmission gears
spacing and gear backlash. With
incorrect gear backlash,
equipment may be damaged.
• When power takeoff requires
bearing or gear replacement,
transmission must be removed in
order to adjust power takeoff gear
and transmission gear backlash.
Failure to adjust backlash may
result in damage to equipment.
Determine oil leak location.
1. If power takeoff cover gasket is
leaking, replace gasket
(WP 0349 00).
2. If power takeoff shifter shaft seal,
rear output shaft seal, input shaft
seal, rear output shaft housing
gasket, or input shaft bearing
cover gasket is leaking oil, remove
power takeoff from transmission
and replace defective parts
(WP 0349 00).
3. If power takeoff gears or bearings
require replacement, remove
transmission (WP 0131 00).
Remove power takeoff from
transmission and replace
(WP 0349 00) or repair
(WP 0464 00).
4. TRANSFER POWER
TAKEOFF LEAKS OIL
Check oil feed line between transfer
case and power takeoff for loose
fittings or damaged line
(WP 0348 00).
1. If oil line fittings are loose,
tighten. If damaged, replace
(WP 0138 00 and WP 0348 00).
2. If gaskets or seals on power
takeoff are leaking, replace
gaskets or seals (WP 0348 00).
