Usage:
Start By:
a. remove drum assembly
| NOTICE |
|---|
Drum support components use elastic stop nuts in several places. After being disassembled, these nuts should be discarded and replaced with new parts. |
1. Attach a hoist and chain to shock mount support (1). Weight of shock mount support is approximately 60 kg (132 lbs.).
2. Raise the hoist enough to support shock mount support (1). Remove the bolts, washers, and nuts securing the shock mounts to bearing housing support (10).
3. Use the hoist to carefully remove shock mount support (1) and shock mounts (9) from the drum support.
| NOTICE |
|---|
Check the condition of the rubber shock mounts. Replace any that show signs of severe cracking, fatigue, or breakage. |
4. Remove the shock mounts from shock mount support (1) if shock mounts are to be replaced.
5. Remove the bolts and washers holding the vibratory motor in place and remove the vibratory motor.
6. Slide vibratory coupling (11) out of bearing housing support (8).
7. Check the condition of bearing (6) as follows:
a. Attach a dial indicator to the drum head. Set the dial indicator against bearing housing support (10), as shown.
b. Push bearing housing support (10) in, toward the drum, as far as possible.
c. Set the dial indicator to zero.
d. Pull bearing housing support (10) out, away from the drum, as far as possible.
e. Distance bearing housing support (10) moves should not exceed .23 mm (.009 in.). If movement is greater than this, replace bearing (8) located inside bearing housing support (10).
NOTE: For information about replacement of bearing (8), see Disassemble Drum Support Assembly (Vibratory Side).
 |
Heavy component. Avoid possible injury. Do not move prior to securely attaching a proper lifting device. |
 |
8. Attach a hoist and chain to bearing housing support (10), this will be used to lift the drum support assembly.
9. Make matching scribe marks on bearing housing support (10) and bearing housing (12).
10. Remove the bolts and washers holding the drum support assembly to the drum. If necessary, raise the hoist slightly to remove load from bolts.
11. Slide a 2440 mm (8 ft.) pipe over the end of the weight shaft. Support the end of the pipe. This will prevent the eccentric weight assembly from dropping when the drum support assembly is removed.
12. Insert three of the bolts, removed in the previous step, in the blind holes of bearing housing (12).
13. Turn the bolts in equally until the drum support assembly is free of the drum.
14. Slide the drum support assembly over the pipe supporting the weight assembly and away from the drum.
15. Place blocks under the weight assembly, then slide the drum support assembly off the pipe.
Install Drum Support (Vibratory Side)
1. Install shock mounts to shock mount support (1) if they were removed during disassembly.

2. Attach a hoist and chain to the drum support assembly.
3. Slide a 2440 mm (8 ft.) pipe over the end of the weight shaft.
4. Use the hoist to raise the drum support assembly and slide the drum support assembly onto the pipe.
5. Remove blocking from under weight and slide drum support assembly to drum head. Align the scribe marks on the drum support assembly with the scribe marks on the drum head.
6. Secure the drum support assembly in the drum head using bolts and washers. Turn the eight bolts in equally drawing the drum support assembly into the drum. Use Locktite 262 on the bolts.
7. Align the splines on the inside of coupling (7) with the splines on eccentric weight shaft (15). Slide coupling (7) into bearing housing support (10).
8. Move the vibratory motor in place against cover plate (2) and secure with bolts and washers. Use Locktite 262 on the bolts.
9. Attach a hoist and chain to shock mount support (1).
10. Use the hoist to raise shock mount support (1). Move into place against bearing housing support (10).
11. Secure the shock mounts to the drum support assembly with bolts, washers, and nuts.

a. Install drum assembly
Disassemble Drum Support Assembly (Vibratory Side)
Start By:
a. remove drum support assembly (vibratory side)
1. Lay drum support assembly on clean, hard surface with cover plate (2) up.
2. Make matching scribe marks on cover plate (2) and bearing housing support (10).
3. Remove the bolts and washers holding cover plate (2) to bearing housing support (10).
4. Remove cover plate (2).
5. Remove lock wire from retainer plate bolts.
6. Remove the bolts and lock washers holding retainer plate (4) in place. Remove retainer plate (4) and shims (5).
7. Attach a hoist and chain to bearing housing support (10).
8. Turn the drum support assembly over so bearing housing support (10) is on the bottom and bearing housing (12) is up.
9. Place three 3/4 inch N.C. x 5 inch long bolts and flat washers in the three threaded holes in bearing housing (12).
10. Attach a hoist and chain to bearing housing (12).
11. Turn bolts in equally until bearing housing (12) is free of bearing housing support (10).
12. Remove bolts and flat washers from bearing house (12).
13. Remove seal (11) from bearing housing support (10) and bearing housing (12).
14. Using a brass drift, tap the bearing race and outer bearing out of bearing housing support (10).
15. Remove bearing spacer from bearing housing (12).
16. Using a suitable puller, remove inner bearing half from bearing housing (12).
Assemble Drum Support (Vibratory Side)
1. Thoroughly clean bearing housing (12) and bearing housing support (10).
2. The bearing seating surface of bearing housing (12) must be free of grease or oil.
3. Make sure oil metering holes, in bearing housing (12) are clean and free of obstructions.

Heavy component. Avoid possible injury. Do not move prior to securely attaching a proper lifting device. |
|
4. Attach a hoist and chain to bearing housing (12).
5. Set bearing housing (12) on a clean, hard surface, plate side up.
| NOTICE |
|---|
Do not grease the seal assembly. Just apply oil to metal parts. |
6. Replace seal assembly (11) in bearing housing (12).
7. Apply Locktite 680 to the bearing seating surface of bearing housing (12).
8. Using an oven, heat bearing cone to 107° C (225° F). Do not overheat the bearing race.
NOTE: If an oven is not available, a torch may be used to heat the bearing. When using this method, the bearing should be placed on a steel plate with the flame directed to the plate in the center of the bearing. Do not place flame directly on bearing. Do not overheat bearing race.
9. Slide the inner bearing onto bearing housing (12).
10. Press the bearing race into bearing housing support (10).
