0.1 REPLACING HYDRAULIC PUMP (FIGURE 0-2)
Note: If the hydraulic tank has not been drained, suitable means for plugging the hoses should be pro-
vided to prevent excessive fluid loss.
Removal
1. Mark, disconnect and plug the hose assemblies.
2. Loosen the capscrews and remove the pump assemblies from the engine.
Installation
1. Lubricate the pump shaft with extreme high pressure molybdenum grease and attach the pumps to the
engine with capscrews.
2. Using a criss-cross pattern, torque each capscrew a little at a time until all four capscrews are torqued to 27
Nm (20 ft. lbs.).
3. Unplug and reconnect the hydraulic hoses.
4. Check the oil level in the hydraulic tank before operating the work platform.
