TRANSMISSION POWER TAKEOFF (PTO) MAINTENANCE (Ccntd)
a. Removal
CAUTION
Prevent dirt from entering transmission and power takeoff when
performing this task. Failure to do so may cause damage to
equipment.
Remove six nuts (6), lockwashers (7), power takeoff (PTO) (5), and gasket (4) from transmission (1).
Discard gasket (4) and lockwashers (7).
Remove gasket material and debris from transmission (1) and PTO (5) mating surfaces.
b. Cleaning
c. Inspection and Repair
1. Check PTO (5) and transmission (1) mating surfaces for scratches, cracks, and galling. Refer to
TM 9-2520-246-34-1 if scratched, cracked, or galled.
2. Check transmission gear teeth (2) for wear, cracks, and discoloration. Refer to TM 9-2520-246-34-1 if
gear teeth are worn, cracked, or discolored.
3. Inspect stud(s) (3). Replace stud(s) (3) if damaged (para. 2-9).

NOT E
Ensure transmission output gear is stabilized while measuring
backlash.
Shift into second gear (TM 9-2320-361-10).
Install new gasket (4) and PTO (5) on transmission (1) with six nuts (6). Tighten nuts (6)
15-20 lb-ft (20-27 N.m).
Set dial indicator on PTO (5) to measure PTO input gear (8) backlash.
a. Check PTO backlash. Backlash should be 0.008-0.012 in. (0.203-0.305 mm).
b. If backlash is 0.008-0.012 in. (0.203-0.305 mm), perform steps 5 through 7.
NOTE
It maybe necessary to use more than one gasket to obtain
0.008-0.012 in. (0.203-0.305 mm) backlash. Each gasket will change
backlash approximately 0.006 in. (O.152 mm).
c. If backlash is less than 0.008 in. (0.203 mm), remove dial indicator and PTO (5) from
transmission (1) and continue with step 7 using two new gaskets (4) to obtain 0.008-0.012 in.
(0.203-0.305 mm) measurement.
d. If 0.008-0.012 in. (0.203-0.305 mm) backlash measurement cannot be obtained, replace (para. 8-2)
and repair (TM 9-2520-246-34-1) transmission (1).
Remove dial indicator from PTO (5).
Remove six nuts (6), PTO (5), and gasket (4) from transmission (1).
