IMPORTANT
1. Read all safety precautions at the front of the
section before attempting any of the following
procedures.
2. See Figures 3-4 and 3-5 for part names.
1. Position the rockshaft under the gauge wheel
mounting brackets.
IMPORTANT
The gauge wheel arms should point to the rear of the
machine with the cylinder anchors facing up.
2. Install the upper bearings.
a. Slip the 3/4-10 X 8-1/2 hex head cap screws
through the holes provided for them in the
mounting brackets.
b. Place the upper bearing halves (with the grease
zerk in the side) on top of the rockshaft. There
are five bearing assemblies on the rockshaft.
c. Use a hoist or forklift to raise the rockshaft. Use
the hex head cap screws to guide the rockshaft
and top bearing halves into place.
3. Set a lower bearing half (with a grease zerk between
the bolt holes) under the rockshaft and through the
hanging ends of the hex head cap screws.
4. Secure each set of bearings tight enough to the
rockshaft to hold the assembly together. Use the
washers and hex lock nuts provided.

5. Insert the rockshaft shims, as needed, between each
set of bearings. Use the shims to allow the rockshaft
to rotate freely, yet not loosely, in the bearing halves.
Repeat this step for each set of bearings. Then
tighten the hex head cap screws.
6. Mount the tires on the wheel rims and assemble to
the hubs. Tighten wheel bolts evenly to assure
proper wheel alignment. Wheel bolts should be
tightened to 90 ft-lbs of torque. The hoist can then be
removed.
IMPORTANT
An 11L X 15" farm service tire should be used on the
15" x 8" rim. Inflate the tire to its manufacturer's
recommended pressure.
7. Install the base end of the gauge wheel cylinders on
the frame cylinder anchors. Face the rod end down,
towards the gauge wheel, and face the ports
upwards (See Figure 3-5.) Secure each cylinder to
the cylinder anchor with the clevis pins and cotter
pins supplied with the cylinder.
8. Position the lockout assemblies above the gauge
wheel arms and the rod ends of the cylinders (See
Figures 3-4 and 3-5.) The open end of the lockouts
should be over the gauge wheel arms with the
U-shaped cutout on the opposite end facing
upwards.
9. Insert the extended cylinder pin through the lockout
assembly, the cylinder clevis and the gauge wheel
arm bracket (See Figure 3-5.) Secure with hairpin
clips.
