Use a tester with pressure and flow capabilities | Toro 3000D

Auxiliary Hydraulic Pump Efficiency Test (Model 30726 Hydraulic Kit)

A worn or damaged pump will by–pass oil and make the pump less efficient. Eventually, enough by–passing will occur to cause the cutting units to to stall in heavy cutting conditions. Continued operation with a worn, inefficient pump can generate a lot of heat and cause damage to seals and other components in the hydraulic system.

Use a tester with pressure and flow capabilities.

Specification:

Minimum 12 GPM (45 liter/min.) at 2,500 PSI (173 Bar)

1.Make sure hydraulic oil is at normal operating temper- ature by operating the machine for approximately 10 minutes.

2.Lower cutting unit, engage parking brake and stop the engine.

3.Disconnect the large pressure hose from the coupler at the pump. Disconnect the large return hose from the coupler at the return filter. Install the tester between the pump outlet and filter inlet.

IMPORTANT: Make sure the oil flow indicator on the flow meter shows that the oil will flow from the pump, through the tester and into the return filter. Make sure the flow control valve is open before starting the engine.

4.Start the engine and move the throttle control all the way forward. Engage the PTO.

5.Slowly close the flow control valve until the gauge reads 2,500 PSI (173 Bar). Read the flow meter. Disen- gage the PTO, stop the engine and open the flow control valve on the tester. If flow is less than 12 GPM (45 liter/ min.) the pump is inefficient and should be repaired or replaced.

Hydraulic System and Transaxle

NOTE: The pump has an integral relief valve that is set at 3,625 PSI (250 Bar). This relief valve protects the pump from shock stress. If you cannot reach 2,500 PSI (173 Bar) when closing the flow control valve on the tester, this relief valve may be stuck open. This could be caused by debris or contamination in the hydraulic sys- tem.
