DRIVE ROLL INSTALLATION

CHANGING DRIVE ROLLS FOR 2-ROLL WIRE FEEDERS

To change drive rolls on a 2-roll wire feeder, refer to Figure B.5 and perform the following steps.

NOTE: Although an LN-9 GMA model is shown in Figure B.5, the following procedure also applies to LN-9F GMA models.

1.Rotate the latch knob on the quick release arm.

2.Remove the hex head screw and clamping collar. Remove the drive roll from the shaft. On new machines, remove the tape and the drive key.

3.The new roll to be installed is stamped for the size to be fed. An "A" after the size indicates aluminum wire. Remove the rolls from the kit and wipe them clean. Wipe the output shaft and locating shoulder clean.

4.Use the drive key, clamping collar, and hex head screw to install the roll on the output shaft. Certain size drive rolls consist of two roll halves, and may contain a spacer. If the drive roll you are installing contains a spacer, the spacer fits between the two halves of the drive roll. Tighten the hex head screw.

5.Back out the guide tube clamping screws. Remove the old guide tubes, if installed.

6.Insert the outgoing guide tube (the one with the plastic insert) into the front hole. If the guide tube has a non-symmetrical chisel end, the larger radius must face the drive roll. See Figure B.5. Push the guide tube back as far as it will go and tighten the clamping screw. Insert the incoming guide tube as far back as it will go and tighten the clamping screw. The clamping screws are dog points. When the guide tubes are properly installed these dog points will lock into the annular grooves in each of the guide tubes.

7.Set the idle roll pressure as detailed in the Idle Roll Pressure Setting procedure detailed later in this section.
