Step 7:
Carefully lift the boiler body and cab off the frame. Note that there will be
connecting wiring for the cab lights and printed circuit board. Care should
be taken not to jerk or pull on the wires. The wiring is not shown in the
diagrams. (See Figure 6)
Step 8:
Remove the electrical tape holding the wiring in place along the channels
of the upper weight. This will allow for the boiler body to be moved out of
the way. It will still be connected via the wiring.
Step 9:
Using a Phillips head screw driver, remove the three screws holding the
top weight in place. Lift the weight out of the way, being careful not to pull
or jerk on the wiring. (See Figure 7)
Step 10:
Lift the motor out of the frame, removing the drive shaft from the gear box
end, and setting the motor to one side. (See Figure 7)
Step 11:
Remove the five screws holding the frame to drive wheel assemblies. Four
screws from the top and one from the bottom of the frame will need to be
removed. Carefully remove the frame, threading excess pickup wires
through the frame to the wheel pickups. (See Figure 8)
Step 12:
Remove the worm gear box cover, and drive shaft from the front drive
wheel assembly. (See Figure 9)
Step 13:
Remove the two screws holding the front drive assembly to the gear box
frame. Remove two screws holding the gear box in place and remove the
gear box. (See Figure 10)
