MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
POWER TAKEOFF
45.
(TRANSMISSION-DRIVEN) POWER TAKEOFF INOPERATIVE
Step 1. Check power takeoff. Engage power takeoff and visually confirm output propeller shaft
rotation.
If propeller shaft is not rotating (but power takeoff is in engaged position), remove
transmission (para. 8-2) with power takeoff. Remove and inspect power takeoff. Repair
(TM 9-2520-246-34-1) or replace power takeoff (para. 16-20).
Step 2. Visually inspect transmission power takeoff drive gear for damage.
If drive gear is damaged, repair (TM 9-2520-246-34-1) or replace power takeoff (para. 16-20).
END OF TESTING!
46.
(TRANSFER-DRIVEN) POWER TAKEOFF INOPERATIVE
If power takeoff is inoperable, replace (para. 16-20) and repair (TM 9-2320-246-34-1). Engage and
visually confirm output propeller shaft rotation.
a. If transfer case half is defective, replace (para. 9-2) or repair (TM 9-2520-246-34-1).
b. If power takeoff is defective, replace (para. 16-20) or repair (TM 9-2520-246-34-1).
END OF TESTING!
47.
TRANSMISSION POWER TAKEOFF LEAKS OIL
Determine oil leak location.
a.
If power takeoff cover gasket is leaking, replace gasket in vehicle (para. 16-22).
CAUTION
b.
c.
. When replacing gaskets between power takeoff and transmis-
sion housing, replace with the 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.
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 (para. 16-20).
If power takeoff gears or bearings require replacement, remove transmission para. 8-2).
Remove power takeoff from transmission and replace (para. 16-20) and repair”’
(TM9-2520-246-34-1).
END OF TESTING!
48. TRANSFER POWER TAKEOFF LEAKS OIL
Check oil feed line between transfer case and power takeoff for loose fittings or damaged line
(para. 16-21).
a. If oil line fittings are loose, tighten. If damaged, replace (paras. 9-2 and 16-21).
b. If gaskets or seals on power takeoff are leaking, replace gaskets or seals (para. 16-21).
