Removing and Replacing Hydrostatic Pump

1.Set the parking brake.

2.Disconnect the battery.

3.Clean the pump and all connections.

4.Mark and disconnect all hoses and lines from the pump.

5.Disconnect the forward / reverse control cable.

6.Disconnect the pump support bracket.

7.Remove the engine mounting bolts.

8.Elevate the pump and engine assembly using a proper lifting device.

9.Disconnect and remove the hydrostatic pump assembly.

10.Repair or replace the hydrostatic pump as required.

11.Install the hydrostatic pump in the reverse order of removal, using Locktite 271 on all mounting bolts and nuts.

12.Test operation.Test and adjust the forward and reverse relief pressures as required. Adjust the forward/reverse control cable.

Removing and Replacing Vibration/ Steering Pump

1.Remove the hydrostatic pump as per preceding instructions.

2.Remove all hoses and lines.

3.Disconnect the vibration / steering pump and remove.

4.Repair or replace pump as required.

5.Install the pump in the reverse order of removal, using Locktite 271 on all mounting bolts and nuts.

6.Test operate. Test and adjust the forward and reverse pressure relief valves as required. Adjust the forward/ reverse control cable.Test and adjust the vibration and steering pressure relief valves as required.

Drums and Main Frame

1.The front drum is designed to apply vibration and compaction force to the operating surface for compaction. This vibration and compaction force is produced when the vibrator shaft is rotated. Maximum efficiency is achieved only when the engine is operated at full throttle.

2.A single drive motor is mounted on the left side of the drum and is shock mounted. This type of drive motor is designed for maximum torque and power.

3.The vibrator is driven by a gear motor coupled to the vibrator shaft.The vibrator assembly rotates inside of a sealed housing containing oil to lubricate the bearings. This side of the drum is also shock mounted.

Front and Rear Drum Removal and Disassembly.

Refer to Figure 32, Figure 33, and Figure 34 for the removal and disassembly of the front and rear drums. When reassembling the front drum, use Locktite 271 on all mounting hardware.
