(1) Gear Pump (Brake, Brake Cooling, Hoist)
(2) Outlet side
(3) Inlet side Performance tests can be used for diagnosing poor performance and for finding the source of oil leakage inside the hydraulic system.
Problem: The Gear Pump (Brake, Brake Cooling, Hoist) makes noise and the cylinder rods do not move evenly. Also, there is air bubbles in the oil.
Probable Cause
The low-pressure relief valve in the Control Valve (Hoist) opens at low oil pressure.
The high-pressure relief valve in the Control Valve (Hoist) opens at low oil pressure.
There is a loose connection in the oil line on inlet side (3) of Gear Pump (Brake, Brake Cooling, Hoist) (1).
Gear Pump (Brake, Brake Cooling, Hoist) (1) is excessively worn.Problem: The temperature of the oil is too hot.
Probable Causes
The viscosity of the oil is incorrect.
The low-pressure relief valve in the Control Valve (Hoist) opens at low oil pressure.
The high-pressure relief valve in the Control Valve (Hoist) opens at low oil pressure.
Gear Pump (Brake, Brake Cooling, Hoist) (1) is excessively worn.
There is a restriction in an oil passage.
The load on the system is too high.Problem: The output of the Gear Pump (Brake, Brake Cooling, Hoist) is too low.
Probable Cause
The oil level of the hydraulic tank is too low.
The viscosity of the oil is incorrect.
Gear Pump (Brake, Brake Cooling, Hoist) (1) is excessively worn.Problem: The pressure of the oil is too low.
Probable Cause
The low-pressure relief valve in the Control Valve (Hoist) opens at low oil pressure.
The high-pressure relief valve in the Control Valve (Hoist) opens at low oil pressure.
Gear Pump (Brake, Brake Cooling, Hoist) (1) is excessively worn.
An O-ring seal failed in the hydraulic system.Problem: The body will not lower.
Probable Cause
There is a problem with the engine speed sensor that is located on the flywheel housing.
