INSTALLATION PROCEDURES

1. Inspect the tapered bore of the hub and the tapered surface of the bushing. Remove any paint, dirt, oil, or grease.
2. Do not use any lubricants in this installation.
3. First slide the shaft through the Drum or Wing then slide the bushings onto the shaft. Pick the drum or wing up and push the bushing into the hub. Line up the solid hole in the bushing to the threaded hole in the hub.
4. Push the bolts through the bushing and start to screw into the hub by hand. Use a tape measure to center the Drum or Wing on the shaft then use a wrench to lightly snug the bolts. Check with a tape measure again and bump the drum or wing to center between the bearings. Once in place torque the bolts based on the table below. Make sure you stagger the sequence of tightening the bolts. Using an accurate torque wrench, tighten each cap screw alternatively and evenly; applying no more pressure than recommended in the torque table. Using a hammer and a heavy steel or bronze bar, tap on the face of the bushing (this is called “drifting”), starting opposite the split. Avoid tapping outside of the bolt circle to prevent damage to the bushing. Continue drifting in clockwise and counterclockwise directions from the point opposite the split around the bushings until you reach the specified torque on all cap screws. For JS or larger bushings, repeat this procedure until the specified torque no longer turns the cap screws after drifting.
5. Tighten the second bushing per Step 4. When two bushings are used, complete tightening of one bushing before proceeding to tighten the second bushing.
6. Do not over tighten the cap screws. The bushing should not pull tight (bottom out) against the hub. Clearance must be maintained. The gap between hub and bushings should be uniform at all locations; surfaces on both sides of the bushing split should be even. Check for undersized shafting, if the bushing flange contacts the face of the hub.

MAINTENANCE

Inspect the bushings and check the torque setting before startup and once a week for the first month of operation. Thereafter, repeat at periodic maintenance intervals.

REMOVAL

1. Clean the exposed shaft ends.
2. Remove all cap screws.
3. Insert the cap screws into all threaded jacking screw holes in the bushing flange.
4. Turn the cap screws against the flange of the hub alternately and evenly in one bushing. A few turns on each screw and the bushing will break loose, releasing the grip of the bushing on the shaft. Do not apply excessive torque on jacking holes adjacent to the bushing split. If bushing does not break loose immediately, tap the bushing with a soft hammer.
5. Remove bushing from the shaft. If necessary, carefully insert a wedge in the bushing split to expand the bushing bore.
6. Repeat Steps 1 thru 5 for the remaining bushing.

SAFETY INFORMATION

1. Follow all federal, state,
   local, and owner
   recommended
   safety guidelines.
2. Before beginning work on a conveyor always lockout and tag-out the equipment. Follow All OSHA and other guidelines that pertain to lockout and tag-out procedures.
3. Only workers who are safety trained and familiar with the mechanics and mechanical nature of conveyors should install pulleys and bushings on
   a conveyor.
4. Do not wear loose clothes, jewelry or neckties when working on or around conveyors. Long hair should be secured under a cap or bandana to prevent injury. The moving parts of a conveyor may catch loose clothes, jewelry, neckties or long hair and may result in serious injury.
5. All conveyors should have safety shut off cable devices in good working condition. If you do not have a safety shut off cable you may call us to obtain one. Frequent tests of this device are required to maintain proper working order.
6. Before starting the conveyor make sure that no one is exposed to the moving parts or material being discharged. The speed of the conveyor and the material being conveyed is sufficient to cause bodily injury.
