CORRECTIVE ACTION

3. TRANSMISSION

CAUTION

POWER TAKEOFF

LEAKS OIL

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).

Check oil feed line between transfer

fittings or damaged line

(WP 0138 00 and WP 0348 00).

(WP 0348 00).

2. If gaskets or seals on power

takeoff are leaking, replace

gaskets or seals (WP 0348 00).
