Usage:
Start By:
a. remove drum support (propel side)
b. remove drum support (vibratory side)
1. Insert three of the bolts, that held outer bearing housing (10) and inner bearing housing (14) in place, into the blind holes in inner bearing housing (14).
2. Turn the bolts in equally.
3. As soon as there is enough gap between the drum head and inner bearing housing (14), attach a hoist and chain to inner bearing housing (14). Weight of inner bearing housing (14) and the eccentric weight assembly is approximately 121 kg (267 lbs.).
4. Slide a 2440 mm (8 ft.) pipe over the shaft end (12). This pipe will be used to counter balance the bearing housing and eccentric weight assembly.
5. Apply downward force to the pipe to keep eccentric weight assembly horizontal.
6. Turn the pusher bolts in until inner bearing housing (14) is free of the drum.
7. Using the hoist, back inner bearing housing (16) and eccentric weight assembly out of the drum. Continue to counter balance the eccentric weight assembly with the pipe.
8. Remove the bolts and washers holding shaft end (12) in place.
9. Slide the eccentric weight assembly out of inner bearing housing (14).
10. Set inner bearing housing (14) on a clean, hard surface flange side up.
11. Make matching scribe marks on plate (19), bearing housing (18), and the drum head on the propel side of the drum.
12. Remove the bolts and washers holding plate (19) in place.
13. Place three of the bolts and washers on the blind holes in plate (19).
14. Turn the bolts in equally until plate (19) is free of drum.
15. Insert three of the bolts and washers, that held plate (19) and bearing housing (18) in place, into the blind holes in bearing housing (18).
16. Turn the bolts in equally.
17. As soon as there is enough gap between the drum head and bearing housing (18) attach a hoist and chain to bearing housing (18). Weight of bearing housing (18) is approximately 32 kg (70 lbs.).
18. Use the hoist to remove bearing housing (18). Set bearing housing on blocks, flange side up.
NOTE: The following steps apply to bearing housings (14) and (18).
19. Rotate the inner race of the vibratory bearing (13) by hand. The race should rotate smoothly with no sign of binding.
20. Examine bearing surfaces for scoring, gouging, or other signs of damage.
21. Insert a feeler gauge between the bearing rollers and the outer race, all the way through the bearing. Maximum allowed clearance is .20 to .25 mm (.008 to .010 in.).
22. If the bearing is damaged, or if clearance exceeds maximum, the bearing should be replaced with a new part.
23. Attach an internal bearing puller to the bearing housing and vibratory bearing (13) as illustrated.
24. Use the puller to remove vibratory bearing (13) from the bearing housing.
NOTE: If vibratory bearing condition will not permit removal by the above method, a torch may be used to cut the inner race and bearings. Weld a bead around the center of outer race. Pull outer race out of the bearing housing.
25. Examine the condition of eccentric weights (15). The eccentric weight should rotate freely on eccentric weight shaft (16) and be free of breaks or cracks.
26. If it is necessary to remove the eccentric weights, slide them off the shaft.
Assemble Inner Drum
1. Thoroughly clean bearing housings (14) and (18).
2. Make sure oil metering holes, in bearing housings (14) and (18), are clean and free of obstructions.
3. If vibratory bearings (13) were removed from bearing housings (14) and (18) during disassembly, press new bearings in place.
4. Remove the o-ring from bearing housing (18) and replace with a new part.
5. Thoroughly clean the inside of drum reservoir.
6. Attach a hoist and chain to bearing housing (18). Weight of bearing housing (18) is approximately 32 kg (70 lbs.).
7. Using the hoist and chain, move bearing housing (18) into position on the drum head. Align the scribe marks on bearing housing (18) and the drum head. Draw bearing housing in place using three mounting bolts.
8. If eccentric weights (15) were removed from eccentric weight shaft (16), slide them back onto eccentric weight shaft (16).
9. Remove the o-ring from inner bearing housing (14) and replace with a new part.
10. Attach a hoist and chain to the eccentric weight assembly. Weight of the eccentric weight assembly is approximately 121 kg (267 lbs.).
11. Place the four bolt pattern end of eccentric weight shaft (16) in bearing (13) and bearing housing (14).
12. Secure shaft end (12) to eccentric shaft (16) using bolts and washers. Apply Loctite 262 to the four bolts before use.
13. Attach a hoist and chain to inner bearing housing (14). Weight of inner bearing housing (14) and eccentric weight assembly is approximately 12 kg (267 lbs.).
14. Slide a 244 cm (8 ft.) pipe over the shaft end (12). This pipe will be used to counter balance the bearing housing and eccentric weight assembly.
15. Apply downward force to the pipe to keep eccentric weight assembly horizontal.
16. Using the hoist, move inner bearing housing (14) and eccentric weight assembly into the drum. Align the scribe marks on inner bearing housing (16) and the drum head.
17. Move the pipe as necessary to align the eccentric weight assembly up with bearing (13) in bearing housing (18).
18. Using the bolts and flat washers, draw inner bearing housing (14) in place.
19. Remove the bolts and flat washers.
20. Remove the three bolts used to draw bearing housing (18) in place, propel side of the drum.
21. Position plate (19), aligning the scribe mark with bearing housing (18) and draw in place using bolts and flat washers.
End By:
a. Install drum support (vibratory side)
b. install drum support (propel side)
