NOTE: The following steps are for the installation of the drum.
6. Attach the drum to a hoist and install it into the machine.
7. Position the shock mount spacer between the shock mount and the yoke assembly. Install eight bolts (4) and tighten to a torque of 100 ±13 N·m (75 ± 10 lb ft).
8. Connect three hose assemblies (3) to the vibratory motor.
9. Install four bolts (2) and tighten to a torque of 355 ± 48 N·m (265 ± 35 lb ft).
10. Connect three hose assemblies (1) to the drum drive motor.
11. Check the hydraulic fluid level. See the "Operation & Maintenance Guide".
Disassemble & Assemble Drum
Start By:
a. remove drum
b. remove drum drive motor
c. remove vibratory motor
d. remove vibratory arm
Typical Example
|
Do not move the drum without securing proper lifting device. Lifting the drum assembly without using the proper link brackets and hoist can cause the drum assembly to spin and fall. This can result in personal injury or equipment damage. Be sure the work area is clear before the drum assembly is moved. |
|
1. Install tooling (A) and a hoist. Position the drum on its end, (vertically), with the vibratory end at the top. The weight of the drum is approximately 1365 kg (3000 lb).
2. Remove six bolts (1) and motor mounting plate (2).
NOTE: When turning out puller bolt (3), snap ring (5) may pop out. This will leave half of the coupling assembly on the weight shaft.
3. Turn out puller bolt (3). Remove insert assembly (4).
4. Remove three screws (6), hytrel element (7) and puller bolt (3).
5. Remove the two bolts and hose guard (8). Disconnect and plug hose assembly (9).
6. Remove bolts (10) that hold the stub shaft to the drum.
7. Remove corks (11) from the puller holes in the stub shaft and install three 1 × 3 1/2 forcing screws.
8. Turn the forcing bolts equally until the stub shaft is free of the drum.
9. Install tooling (A) and attach a hoist. Remove the stub shaft. The weight of the stub shaft is 159 kg (350 lb).
10. Remove the screws and retainer plate (12).
11. Remove seal (13) and bearing (14) from the eccentric weight housing.
12. Remove the key from the shaft. If necessary, use tool (B) and remove flange hub (15).
13. Remove bearing spacer (16).
14. Remove the bolts and retaining plate (17). Remove the bearing.
15. Using tooling (C), remove the hub from the shaft.
16. Remove ring wiper (18) from the hub.
17. Install tooling (A) on the stub shaft. Remove the stub shaft from the eccentric weight. The weight of the stub shaft is 91 kg (200 lb). The weight of the eccentric weight is 34 kg (75 lb).
18. Remove bearing (19).
19. Position the stub shaft with the inner side up. Remove the screws and retainer (21). Remove seal (22) and bearing (20).
20. Using tooling (A) and a hoist, position the drum horizontally. Block the drum to keep it from moving. Remove cap plugs (23) from the rear of the eccentric weight housing.
21. Install two bolts, (2-7/16 N.C. × 3 in.), into the cap plug holes. Tighten the bolts down evenly until the bearing is pushed out. Remove the bearing.
22. Support the eccentric weight housing with a lifting device such as the forks of a lift truck. Remove six bolts (24) and separate the housing from the drum. The weight of the eccentric weight housing is 100 kg (75 lb)
NOTE: The following steps are for the assembly of the drum.
NOTE: Make sure all parts are clean. Inspect for wear or damage and replace as required. If the bearings are replaced, replace the corresponding race.
NOTE: When heating parts for assembly, keep flammable materials away from the heat source. Use appropriate safety equipment to avoid personal injury. Hot parts can cause severe burns.
23. Using a support such as a lift truck, position the eccentric weight housing in the drum and install it with six bolts (24).
24. Using a torch, heat the bearing holder in the eccentric weight housing to 83°C (180°F).
25. Install bearing (14) into the heated eccentric weight housing. If necessary, use a brass drift to carefully tap the bearing against the outer bearing race to seat the bearing.
26. Fill the indentation side of seal (13) with clean grease and install the seal with the greased side towards the bearing. Crimp the edges of the seal with a screwdriver to hold it in position.
27. Install retainer (12) with the bolts. Use a center punch to punch the bolt heads twice (where indicated) to add to the bolt retention.
28. Using a hoist, install the eccentric weight into into the drum.
29. Heat the stub shaft to 83°C (180°F).
30. Install bearing (20) into the stub shaft. A brass drift may be used against the outer bearing race the tap the bearing into place.
31. Fill the indentation side of seal (22) with clean grease and install the seal with the greased side towards the bearing.
32. Using new bolts, install retainer (21) and torque the bolts to 40 N·m (30 lb ft). Use a center punch to punch the bolt heads twice (where indicated) to add to the bolt retention.
33. Heat bearing (19) to 83°C (180°F) and install it onto the stub shaft (using a brass drift to seat the bearing if necessary).
34. Install ring wiper (18) into the hub. Thoroughly grease the hub slots with clean grease and install the hub onto the stub shaft.
35. Install the outer bearing onto the stub shaft. Install bearing spacer (16).
36. Install retainer (17) with the bolts. Tighten the bolts to a torque of 48 N·m (35 lb ft).
37. Install flange hub (15) and the key onto the shaft.
38. Using a hoist, install the stub shaft assembly into the drum making sure the bolt holes are properly aligned.
39. Install bolts (10)
40. Install hose guard (8) with the two bolts. Connect hose assembly (9).
NOTE: Pack the coupling assembly with clean grease before assembling.
41. Install hytrel element (7), three bolts (6). Loosely install puller bolt (3).
42. Install insert assembly (4) and snap ring (5). Tighten puller bolt (3) to approximately 107 N·m (78 lb ft) to seat the coupling assembly on the weight shaft.
43. Install motor mounting plate (2) with six bolts (1).
44. Using tooling (A) and a hoist, position the drum horizontally.
