Checking Fluid Leakage

Checking Fluid Leakage

Check the hydraulic piping lines for improper attachment, leaks, cracks, damage, loose connections, chafing and deterioration.





CAUTION:

Do not reuse copper sealing washers.

1) Run the engine until the fluid temperature reaches 50° - 80 °C (122° - 176 °F) in the reservoir tank. Keep engine speed idle.

CAUTION:
Do not allow steering fluid in the reservoir tank to go below the MIN level line. Check tank frequently and add fluid as needed.

2) Turn the steering wheel to the right and left several times.
3) Hold the steering wheel at each "locked" position for five seconds to check for fluid leakage.

CAUTION:
Do not hold steering wheel in the locked position for more than 10 seconds. (There is the possibility that the oil pump may be damaged.)

4) If fluid leakage at a connection is noticed, loosen the connection and then retighten. Do not over-tighten connector as this can damage O-ring, washer and connector. Refer to Testing and Inspection and Service and Repair.
5) If fluid leakage from the oil pump is noticed, check the oil pump. Refer to Testing and Inspection.
6) Check steering gear boots for accumulation of fluid, indicating a leak from the steering gear.
