Center Frame Roller Installation
NOTE
Wheel Stop is on the Clamp side of the Roller Assembly
NOTE
Crowfoot Wheel Rotation Arrow must follow the direction
of travel. See Figure 2-5.
Roller Assemblies are pre-assembled from the factory with
trunnion bearings, shims, and retaining washers. Crowfoot
Wheel Rotation Arrow must follow the direction of Travel.
See Figure 2-5.
1. Loosen the 1-8 Bolt on each end of the Roller
Assembly approximately 4 turns.
2. With the Bearing Grease Fitting facing towards the
rear of the machine, slide the Trunnion Bearing
Mounts onto the Trunnion Bearings and lift the Roller
Assembly up to the Center Frame Bearing Hangers.
Hand tighten 3/4-10 hardware to hold Trunnion
Bearing Mounts in place. See Figure 2-7.
3. Look at each Trunnion Bearing Mount to make sure
that it is sitting perpendicular to the Center Frame
Bearing Hanger. See Figure 2-6. If not adjust the
Shim Washers accordingly, for each side there are
two 11ga and one 14ga Shim Washers. Shim
Washers can be all three on the inside between the
Stub Shaft shoulder and the Trunnion Bearing, all
three can be on the outside between the Trunnion
Bearing and Flat Top Washer, or a combination on
either side, but all three must be used to minimize the
gap. If gap cannot be properly minimized with bearing
snap rings to outside, turn bearing around to have
snap ring to inside. The bearing inner race is offset
with respect to the trunnion bosses by 1/32". By
installing bearings with snap rings in versus out, 1/16"
difference can be made up at assembly if needed.
4. Tighten 3/4-10 and 1-8 hardware to specification per
torque chart. See Page 4-1.
