TM 9-2350-273-BD TRACK AND SUSPENSION 6. If studs are not available, or old studs cannot be removed. Weld the hub on as shown. 7. Use the remaining parts of studs to align hub to final drive and weld in place with a continuous bead. 8. Reinstall track assembly. 9. Record BDAR action taken. When the mission is completed, as soon as practicable, repair tank using standard maintenance procedures. 9-11. SUPPORT ROLLER DAMAGED a. Return rollers keep the track from sagging as it moves from the sprocket to the idler and are necessary to keep the track from being thrown caused by hitting the hull center section. With no rollers, tank operation should be restricted to self evacuation. b. Return roller damage that would provide jagged edges which could snag the track must be corrected. A roller that will not turn is less of a problem than a bare stub shaft which would catch the track and break or throw it. F-or rollers that will not turn, disassemble and clean. The bearings may be damaged and need replacing. If the roller is broken attempt to turn so that the smoothest segment is up and provides a sliding surface for the track. Weld the bearing and roller hub in this position so they will not turn. Other Options: l When the roller is totally missing or cannot be made to provide a smooth sliding surface, it will be necessary to cut off the hub with a torch. 9-8
