8.12 Re-installing the Drum

Prerequisites

 Loctite

243 or equivalent

 Crane and lifting devices capable of lifting 450 kg (1000 lb)

Procedure

Perform the procedure below to re-install a drum.

1. Using Loctite 243 or equivalent on four screws, secure the exciter-side drum

support (a) to the drum. Torque the screws to 240 Nm (148 ft.lbs.).

2. Assemble the drive motor to the drive-side drum support. Assemble the shock

mount support plate to the drive motor. Then, assemble the drum support to the

drum. See Topic Removing and Installing Drive Motors.

3. Position the drum so that the drum supports rest on the ground.

4. Manually release the brake on the drive motor. See Topic Manually Releasing

Parking Brake.

5. Roll the drum into position under the machine. Align it with the marks (b)

previously placed on the floor during disassembly.

6. If the shock mounts were changed, a new shim arrangement (d) may be

necessary. Temporarily attach the large spacers (e) to the machine with the

previous shim arrangement. Rotate both drum supports (f) up from the floor to

the machine. Measure both sides and determine the shims required. Add or

subtract shims as needed.
