Technical Manual

Troubleshooting

Adequate maintenance and proper fluid selection should keep hydraulic problems to a minimum. If troubleshoot-

ing is necessary, ensure that the technician is well-trained in hydraulic systems, and familiar with the equipment

design, assembly and operation. Knowledge of hydraulic circuits and components is essential in isolating trouble

areas and pinpointing particular faults.

The following troubleshooting guidelines are intended to be general in nature. Any faults not solved through the

use of this guide should be referred to our engineering department for their evaluation and recommendations.

A. PUMP MAKES EXCESSIVE NOISE

1. POSSIBLE PROBLEM: Plugged or restricted intake line.

SOLUTION: Clean intake line.

2. POSSIBLE PROBLEM: Plugged reservoir air vent.

SOLUTION: Clean or replace.

3. POSSIBLE PROBLEM: Fluid viscosity too high due to ambient temperature.

SOLUTION: Replace fluid with a type that maintains the proper viscosity range in the

operating environment.

4. POSSIBLE PROBLEM: Air leaking into system.

SOLUTION: Ensure oil pickup is well below oil surface level in reservoir. Check pump pack-

ing and line connections on intake side by pouring oil over the suspected leak. If the noise

stops, the leak has been located. Tighten joints or change packing or gaskets where

necessary.

5. POSSIBLE PROBLEM: Loose or worn parts.

SOLUTION: Replace parts. NOTE: Improper selection of hydraulic fluid may result in prema-

ture wear.

6. POSSIBLE PROBLEM: Pump misalignment with motor.

SOLUTION: Check alignment.

7. POSSIBLE PROBLEM: Pump running in excess of rated speed.

SOLUTION: Check manufacturer’s recommended speed. Check pulleys, gears, power take-

off, or drive motor.
