3-3 2325 ROCKSHAFT INSTALLATION
IMPORTANT
READ ALL SAFETY PRECAUTIONS AT THE
FRONT OF THIS SECTION BEFORE ATTEMPT-
ING ANY OF THE FOLLOWING PROCEDURES.
IMPORTANT
SEE FIGURE 3-2 FOR PART NAMES.
3-3.1 Position the rockshaft under the gauge
wheel mounting brackets.
IMPORTANT
THE GAUGE WHEEL ARMS SHOULD POINT
TOWARD THE REAR OF THE MACHINE WITH
THE CYLINDER ANCHORS FACING UP.
3-3.2 Install the upper bearings.
a. Slip the 3/4" x 8-1/2" 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 rock-
shaft with grease zerks away from the gauge
wheel arms. There are five bearing assem-
blies on the rockshaft.
IMPORTANT
BE SURE TO INSTALL THE FIFTH BEARING IN
THE CENTER, TO ITS PROPER MOUNTING
BRACKET.
c. Use a hoist or forklift to raise the rockshaft.
Use the cap screws to guide the rockshaft
and top bearing halves into place.
3-3.3 Set a lower bearing half (with a grease
zerk between the bolt holes) under the rock-
shaft and through the hanging ends of the
cap screws.
3-3.4 Secure each set of bearings tight
enough to the rockshaft to hold the assembly
together. Use the washers and locking nuts
provided.
3-3.5 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 cap screws.
3-3.6 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 RECOM-
MENDED PRESSURE.
3-3.7 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 Fig-
ure 3-3) . Secure each cylinder to the cylin-
der anchor with the clevis pins and cotter
pins supplied with the cylinder.
CAUTION
BE SURE EACH CYLINDER HAS A
RESTRICTOR FITTING IN THE BASE
END. FAILURE TO DO SO WILL
CAUSE THE ROCKSHAFT TO FAIL.
3-3.8 Position the lockout assemblies above
the gauge wheel arms and the rod ends of
the cylinders (See Figures 3-2 and 3-3 ).
The open end of the lockouts should be over
the gauge wheel arms with the U-shaped
cutout on the opposite end facing upwards.
3-3.9 Insert the extended cylinder pin through
the lockout assembly, the cylinder clevis and
the gauge wheel arm bracket (See Figure
3-3 ). Secure with hairpin clips.
