7-13. GEAR UNIT AND MAIN SHAFT ASSEMBLY REMOVAL/REPAIR/
Front, center, and rear carrier assemblies are disassembled the
same way. Disassembly of center carrier is shown.
Position center carrier assembly (5) with drilled ends
of pinion pins (27) upward in press.
Press pinion pins (27) from center carrier
Remove pinions (24), roller bearings (29), steel thrust
washers (30), and bronze thrust washers (31) from
center carrier assembly (5).
Adhesives, solvents, and sealing compounds can burn easily,
can give off harmful vapors, and are harmful to skin and
clothing. To avoid injury or death, keep away from open tire
and use in well-ventilated area. If adhesive, solvent, or sealing
compound gets on skin or clothing, wash immediately with soap
Clean all metal parts with drycleaning
All planetary gears in a carrier assembly are replaced as a set.
Inspect parts for damage. Replace damaged parts.
Measure thickness of thrust washers. Thickness must be no less than 0.091 in. (2.31 mm)
Bearing surface measurement will be used in
paragraph 7-16 to find output shaft bushing
Measure and note diameter of bearing
surface (1) of main shaft (2).
Measure diameter of front carrier bearing
Measure inside diameter of bushing (4).
If bushing (4) to front carrier bearing
surface (3) clearance is greater than
0.0072 in. (0.15 mm), replace bushing.
Measure diameter of bearing surfaces (2
and 5) on main shaft.
Measure inside diameter of bushings (6 and 7) in sun gear shaft (8).
If clearance between bushings (6 and 7) and bearing surfaces (2 and 5) is more than 0.0064 in.
(0.16 mm), remove bushings.
