5a. The bearing surface that the low gear

rides-on (opposite end from the brake
rotor spline, measured inboard from the
snap-ring groove) should be a minimum
of .617” (15.672mm) diameter.
See Figure 2.115.

5b. The bearing surface that the forward gear

rides on (largest cross-section of shaft,
adjacent to large set of dog teeth) should
be a minimum of 1.144” (29.058mm).
See Figure 2.116.

5c. The bearing surface that the reverse gear

rides on (second largest cross-section of
shaft, adjacent to large set of dog teeth)
should be a minimum of .970”
(24.638mm). See Figure 2.117.

NOTE: If there is significant wear to any of the
bearing surfaces, it is also very likely that the
corresponding gear will have to be replaced.
The bearing surfaces on the inside diameters of
the low and reverse gears are significantly softer
than the bearing surface of the shaft.

NOTE: The forward gear does not require a
bearing insert because there is a lower speed
differential between the gear and the shaft.

Inspect the sleeve that the reverse idler gear
rides-on. If there is any scoring or heat discolor-
ation, replace the sleeve and the reverse idler
gear. See Figure 2.118.
