CHANGING DRIVE ROLLS FOR FOUR- ROLL WIRE FEEDERS:
To change drive rolls on a
1.Remove the gun and cable from the conductor block on the feeder by loosening the hand screw and pulling the gun straight out of the block.
2.Open both quick release levers by moving the levers outward and pulling them toward you.
3.Loosen the thumb screws holding the guide tubes in place. Remove the incoming and outgoing guide tubes, if installed.
4.Remove the hex head screws and clamping collars from the output shafts. Remove the drive rolls and middle guide tube, if installed. On new feeders remove the tape and drive keys.
5.The new rolls to be installed are stenciled with the wire size that will be fed. An “A” after the number indicates aluminum wire. Remove the rolls from the kit and wipe them clean. Wipe the output shafts and locating shoulders clean.
6.Install one roll onto either output shaft using the drive key, clamping collar, and hex head screw. 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.
7.Install the middle guide tube, but do not tighten at this time. When installing a 0.035” middle guide tube the larger radius should be aligned towards the drive roll. Slide the guide tube up against the drive roll.
8.Install the second drive roll on the remaining shaft the same way as the first. Center the middle guide tube between the rolls and tighten the thumbscrews holding it in place.
9.Close and latch both quick release levers.
10.Slide the incoming guide tube into the rear hole of the gearbox until it almost touches the drive roll and guide tube. Tighten the thumbscrew to hold it in place.
11.Install the outgoing guide tube into the front hole of the gearbox (through the conductor block) and tighten the thumb screw. The 0.035 in. outgoing guide tube should have the larger radius oriented toward the drive roll. For proper installation of the outgoing guide tube insert, refer to Figure B.3.
12.Be certain that the guide tubes do not touch the drive rolls or idle rolls. If they do touch, readjust them and tighten in place.
