Drive Motor Removal
(See Figure 2-7.)
The VP drive motors consist of three sections, the gear
box atttached to the rear of the drive motor, the electric
drive motor itself, and the brake assembly mounded at the
front of the drive motor. Each drive motor is mounted inde-
pendently of the other on a completely removable drive
assembly weldment at the back of the machine.
1. Disconnect the positive battery terminal from the left
side battery.
2. Remove the rear plate weldment from the machine,
(plate with the tie down lug) and set aside. Three (3)
bolts hold the top of the rear plate weldment to the
base frame, four (4) bolts attach it to the motor cover
weldment (located under machine) at the back and
on the sides.
3. Carefully raise the lift to gain access to the under-
side of the base frame. Refer to Section 2.4, "Posi-
tioning Lift For Access to Components Located
Under the Base Frame".
4. Remove the remaining two (2) bolts attaching the
motor cover to the base frame and set it aside.
5. Disconnect the wiring connectors to the drive motor
and the brake assembly on either or both sides,
depending on which drive assembly(ies) is being
removed.
6. Disconnect the manual release brake cable from the
brake assembly arm on either or both drive motors if
removing the complete drive assembly.

Step 7. If removing the complete drive assembly
with both motors attached go to Step 11.
7. Remove the one (1) bolt, nut, and two (2) washers
from the front of the drive motor mounting plate.
8. While holding the drive motor in place, remove the
remaining two (2) bolts with washers holding the
drive motor mounting plate to the drive motor
assembly weldment.
