Hydraulic System Maintenance

Figure 7

13 Optional Maximizer

Inspecting the Pump

If the pump is adequately maintained and works smoothly, it will provide a satisfactory output.
However, if the pump whines, vibrates or rattles, apply the following inspection procedure.

To inspect the pump, proceed as follows:

Ensure that the parking brake is applied and that the vehicle is tagged out for maintenance

purposes.

Start the engine and engage the hydraulic pump.

OTE

The pump should turn freely without any excessive noise or vibrations.

Inspect the connections for any loose fittings.

Check underneath the pump for any oil leaks.

If there is no electrical power, refer to the electrical schematics provided with the truck.

Adjusting Main Relief Valve Pressure

It is recommended to verify the pressure setting once every month to prevent damage to the

equipment and make sure it operates as efficiently as possible. If the pressure is not at the

recommended setting, the main relief valve needs to be readjusted. Refer to the pressure adjustment

table (see

Pressure and RPM Table

on page 85) for proper settings.

Most of the hydraulic valve sections operate at 2000 psi except for the Maximizer section, if equipped.

For details, refer to the hydraulic system schematics.
