Axle Suspension Pump And Oil Lines For The Axle Suspension Pump (1) Pump outlet line (2) Axle suspension pump (3) Drain oil line (4) Supply oil lineWhen the axle suspension pump is in operation, some of the oil from the pistons in the pump does not flow through pump outlet line (1) into the axle suspension system. The pump oil that does not flow into the axle suspension system flows into the pump body for lubrication to the parts that move. This oil is leakage. The oil flows through the pump drain oil line (3) to the hydraulic tank.When there is an increase in the pressure of the oil from the pump, the amount of oil leakage increases. Also, when the parts in the pump wear, the amount of oil leakage increases. The amount of oil leakage through drain oil line (3) to the hydraulic tank is an indication of the condition of the pump.
Make sure that the oil in the hydraulic tank is at the full mark on the gauge. Start the engine and operate the bowl until the temperature of the hydraulic oil is 63° to 68°C (145° to 155°F).
Make sure that the control switch is in the LOCKDOWN position. Stop the engine.
Keep the end of the disconnected pump drain oil line (3) above the level of the axle suspension pump. Oil must not drain from the pump body when
