NOTE
Bearing surface measurement will be used in paragraph 6-58 to
find output shaft bushing clearance.
(4)
Measure and note diameter of bearing surface (1) of main shaft (2).
(5)
Measure diameter of front carrier bearing surface (3).
(6)

(7) If bushing (4) to front carrier bearing surface (3) clearance is greater than 0.0072 in. (0.18 mm),
replace bushing.
(8)
Measure diameter of bearing surfaces (5 and 5A) on main shaft (2).
(9)
Measure inside diameter of bushings (6 and 7) in sun gear shaft (8).
(10) If clearance between bushings (6 and 7) and bearing surfaces (5 and 5A) is more than 0.0064-in.
(0.16 mm), remove bushings.
