7.
Insert the input sector gear into the internal cam.
NOTE: The input sector gear and the internal
cam have a master spline to time the two to
each other. See Figure 6A.57.
8.
On the 618-04430 gear boxes, place the smaller
washer over the steering shaft.
See Figure 6A.58.
9.
Assemble the output bevel gear assemblies.
9a. Insert the shaft of the left speed cam into the
left hydro arm. See Figure 6A.59.
9b. Place a bushing over the hydro arm with the
flange facing away from the arm.
See Figure 6A.59.
9c. Place a .030” shim over the hydro arm.
NOTE: The bevel gear needs to be shimmed to
a bind. That means that once the assembly is
installed in the lower housing, there is zero play
between the bushing and the bevel gear. It may
take a few attempts to get the shims correct.
9d. Place the output bevel gear on the hydro
arm with the chamfer facing away from the
hydro arm. See Figure 6A.59.
NOTE: If the output bevel gears are put on back-
wards it will throw off the timing of the gearbox.
NOTE: The hydro arms and output bevel gears
have master splines to time them to each other.
See Figure 6A.60.
