Rear Integrated Hub Wheel Installation - Pin
Brakes
1. Install the integrated hub wheel onto the spindle.
2. Install the castle nut and the flat washer. Finger
tighten the nut.
3. Use a wrench to manually disengage the pin
brakes on both sides. This will allow you to rotate
the wheel.
4. Rotate the hub/wheel slowly while tightening the
castle nut to approximately 68 Nm (50 ft-lb). This
is to seat all the bearings in the wheel assembly.
NOTE
Do not over-torque the castle nut as the bearing
life would be reduced.
5. Loosen the castle nut to remove the torque. Do
not rotate the wheel.
6. Finger tighten the castle nut until it is snug.
NOTE
The castle nut should be free to rotate, with the
only restraint being the cotter pin.
7. Use a wrench to re-engage the pin brakes on
both sides. Do not lower the machine while the
pin brakes are disengaged.
8. Turn the castle nut back slightly until the next
cotter pin hole is visible on the spindle.
9. Install a 1/8” x 1-1/2” cotter pin. Make sure the
cotter pin is pushed in completely to allow the
dust cap to fit.
10. Bend the ends of the cotter pin to secure the
castle nut.
11. Install the dust cap over the castle nut. Be sure
not to damage the castle nut while installing the
dust cap.
