REMOVAL PROCEDURE

WARNING

ELECTRIC SHOCK can kill.

High voltage is present when input power is applied to the machine.

1.Disconnect main input power to the machine.

2.Remove the wire gun and wire.

3.Lift the tool tray door to allow access to the tool tray.

4.Using the 5/16 in. nutdriver, remove the tool tray (3 screws) to gain access to the motor/gearbox assembly.

5.Disconnect motor leads 831 and 832 and tach leads 841, 844 and 847at their in-line connectors. See the Wiring Diagram.

6.Using a 9/16 in. wrench, remove the bolt, lock washer, flat washer and positive lead from the wire drive assembly. Using pliers, remove the hose clamp and flex hose from the wire drive assembly. (Depends on the type of gun being used).

7.Rotate the adjustment arm assembly counterclock- wise to release the tension on the idle arm.

8.Swing the idle arm up and away from the wire drive assembly.

9.Remove the outer guide assembly from the wire drive assembly by loosening the thumb screws until the outer guide can be removed. Rotate the molded keeper until the ears line up with the slots on the drive roll, then pull the drive roll off the shaft assembly. Now slide off the inner guide.

11.Using a Phillips head screwdriver, remove the 3 pan head screws and lock washers securing the motor/gearbox assembly to the wire drive assem- bly.

12.Grasp the motor/gearbox assembly and wiggle it gently back and forth until it separates from the wire drive assembly.

13.Using a 5/16 in. nutdriver, remove the 3 screws holding the wire drive compartment (with wire drive assembly still attached) to the divider panel welded assembly. Pull the compartment away. The motor and gearbox can now be removed.

14.Using a 7/16 in. nutdriver, remove the 3 hex head cap screws, lock washers, and flat washers secur- ing the wire drive assembly to the wire drive com- partment.

15.Remove the wire drive assembly from the wire drive compartment.

For Codes 10958 & Above. See Figure F.12.

10.Using a 9/16 in. wrench to remove nut that holds molded drive roll shaft assembly to the wire drive assembly. Remove the molded drive roll shaft assembly form the wire drive assembly.

11.Using a 7/16 in. wrench remove panel covering the gear.

12.Using a Phillips head screwdriver remove gear.

13.Using a Phillips head screwdriver, remove the 3 pan head screws and lock washers securing the motor/gearbox assembly to the wire drive assem- bly.

14.Grasp the motor/gearbox assembly and wiggle it gently back and forth until it separates from the wire drive assembly.
