Rear planetary carrier assembly inspection.
(a)
Position rear planetary carrier
assembly (7) on level work surface
with splined hub pointing up.
(b)
Visually inspect rear planetary carrier
assembly (7) for evidence of chipped
gear teeth, overheat indication or
metal contamination.
NOTE
If rear planetary carrier assembly
does not meet specification,
replace rear planetary carrier
assembly.
(c)
Check end play of pinions (8). With thrust washer (9) held flat, insert feeler gage between rear
carrier assembly and thrust washer. End play must be within 0.008 to 0.031 in. (0.203-0.787 mm).
(d)
NOTE
Measure clearance in Steps (12), (13) and (14) by measuring inside diameter and outside
diameter of parts. Subtract small value from larger value to determine clearance.
(12)
Measure clearance (A) between sun gear shaft bushings (10) and main shaft (11). Maximum clearance is
0.0085 in. (0.2159 mm). If tolerance is exceeded, replace sun gear shaft.
(13)
Measure clearance (B) between sun gear shaft (12) and support bushings (13). Maximum clearance is
0.0085 in. (0.2159 mm). If tolerance is exceeded, replace support bushing.
NOTE
Front carrier bushing dimensions were measured and recorded in Center Support Repair
(Para 23-17 c. Cleaning/Inspection).
(14)
Determine clearance (C) between front carrier bushing and sun gear shaft (12). Maximum clearance
0.0072 in. (0.1829 mm). If tolerance is exceeded, replace front carrier bushing.
