Removal, Repair and Replacement See figure 3-56.
This procedure assumes a complete removal, repair and replacement of the assembly. A partial disassembly repair and
replacement is possible. Follow the procedure to the point of removing only those components requiring repair or
replacement.
If additional removal or repair is required at the head shaft, do not complete the assembly in this section until the other
work has been completed.
A.
Disassembly
1.
Disconnect and lock out the breaker for the feed conveyor motor.
2.
Remove the two piece guard on the belt drive (see Section 3-8-2).
3.
Loosen the jam nuts on the gear reducer torque arm and adjust the turnbuckle so that the belts can be removed.
Remove the belts.
4.
Remove the junction box cover on the electric motor. Label the electrical wires and disconnect the three power
wires and the ground. Disconnect the ground strap from the electric motor to the frame.
5.
Remove the four bolts holding the electric motor to the base.
6.
Remove the gear reducer from the head shaft following the instructions in Section 3-8-7.

B.
Inspection
1.
Inspect the drive belts and replace if belts are damaged or broken. Check the length of each belt in the set to
determine if they are identical. Replace the belts with a matched set if one belt has a different length than the
other.
