Note

Bevel gear (motor) and bevel gear (receiver) (WP 0067 00) are parts of a serialized, matched set. Both gears must be replaced if either part is defective.

There are two configurations of matched bevel gear sets. The standard gun must use 12524257 and the enhanced gun must use 12524549.

There are two configurations of direct current motors. The standard gun can use either motor; however, the enhanced gun must use 12524409.

2. INSPECT AUTO GUN RECEIVER.

Visually inspect auto gun receiver for loose or damaged screw threaded inserts. If either of these conditions are found, send auto gun receiver to Direct Support Maintenance for repair.
