14. Once the stub shaft is free of the housing, lower the stub shaft to the floor with the inner side up. 15. Remove the bearing retainer plate. 16. Remove the weight bearing by using a suitable puller or driver. Run grease through the lube hole (N) to make certain it isn't blocked. 17. Remove weight shaft (0) using 6' and 3' pipes slipped over the shaft ends. C. Drum Reassembly
1. Using a 6' and 3' length of pipe, insert weight shaft into drum. The end with the 6' shaft should enter drum first. 2. Using a slow circular motion, evenly heat the entire stub shaft flange with a torch to approximately 180° F. (82°C).3. Slide the weight bearing into the stub shaft. 4. If the bearing doesn't seat a brass drift may be carefully used to tap the bearing into place. Only use the brass drift against bearing outer race. 5. Using new self locking bolts, bolt the bearing retainer plate into place. Torque the bolts to 30 ft. lbs.. 6. Tap the retainer plate with a brass drift to further seat the bearing. Recheck the torque on the bolts to make certain they are at 30 ft. lbs..7. Remove pipe and use a hoist to position stub shaft and align bolt holes. If roll pins are not present, align mark on stub shaft with mark on drum head.8. Once stub shaft is aligned, tighten budd nuts.9. Replace stub shaft on other side of drum using steps 7 and 8.10. Use a dial indicator to check that weight shaft end play is between .032 and .316 in. (.8 and 8.0 mm). Remove and or add shims as necessary for correct end play.11. Reattach grease line to stub shaft and drum. 12. Using an oil bath or an oven, heat the bearing to 180°F. (83°C). If the methods mentioned above are not available, a torch may be used to heat the bearing. When using this method, the flame should be centered on a steel plate where the bearings sit. DO NOT place the flame directly on the bearing.
Parts heated to 180° will cause immediate burns if touched with bare skin. Asbestos or suitable gloves should be used for handling bearings or injury will result.
13. Slide the inner bearing half onto the stub shaft. (Before doing this, make certain the surface of the stub shaft is clean.) 14. Place the middle spacer onto the stub shaft next to the bearing. 15. Drive the two races with oil ring placed between the races into the hub using a flat board and a mallet. a. Once the race is flush with the surface of the hub place the spacer against the race and using the flat board and mallet drive the race to the rim inside the hub. Remove the spacer. 16. Thoroughly grease hub slots on the stub shaft and position the hub on the stub shaft. 17. Heat the outer half of the tapered bearing, using the same
