Assembling the Joint Yoke
Installing the Lift Arm Joint Yoke
Chassis: Service and Repairs
D. Repeat process for remaining bearing.
E. Thoroughly clean and inspect all components.
1. Apply a coating of grease to the bearing bores of the yoke and base mounts.
Also, apply grease to the bearings and seals of the cross assembly.
2. Press one bearing partially into the yoke.
Take care when installing the cross into the bearing to avoid
damaging the bearing seal.
3. Carefully insert the cross into the bearing and yoke.
4. Hold the cross in alignment and press the bearing until it hits the yoke.
5. Carefully place the second bearing into the yoke bore and onto the cross
shaft. Press the bearing into the yoke.
6. Install the snap rings to the bearings to secure the bearings in place.
7. Install the remaining bearings on cross.
8. Press the base mounts onto the bearing caps with the angled edge of the
mounts away from the joint; refer to
bearing cups should be flush with the base mount surfaces.
9. Ensure that the assembled joint yoke moves without binding. Slight binding
can usually be eliminated by lightly rapping the yoke lugs with a soft faced
hammer. If binding continues, disassemble joint yoke to identify and eliminate
source of binding.
1. Install the joint yoke to the lift arm:
A. Place a 4.2 mm (0.165 in) spacer (9) and then 3.2 mm (0.125 in) thrust
washer (4) onto the joint yoke shaft.
B. Insert the yoke shaft up through the lift arm bushings.
C. Place a 3.2 mm (0.125 in) thrust washer (4) onto the joint yoke shaft
followed by a 0.8 mm (0.032 in) thrust washer followed by a hardened
washer (3). Use additional 0.8 mm (0.032 in) thrust washers as needed
to remove as much clearance as possible between the thrust washer
and the hardened washer.
D. Install the slotted hex nut (2) to secure the joint yoke to the lift arm.
Torque tighten the nut from 204 to 244 N·m (150 to 180 ft−lb). Ensure
that the joint yoke rotates in lift arm without binding and that excessive
clearance does not exist in the yoke assembly.
2. Carefully lower the lift arm to position base mounts to the cutting unit
connection.
Note: Orient yoke with the grease fitting towards the outside if the machine.
