5. Oil Level Check
Correct oil level depending on the version.
6. Leak Testing
A power steering/tandem pump must only be replaced if oil leakage (pronounced formation of droplets) has been established and the oil level is
below the minimum marking.
A slight oil film on the radial seal ring or on the housing joint face is due to the system.
a) Leakage at the Pipe Connections:
Retighten high pressure hose. If this is not successful, the connection nipple must be checked for damage. If necessary. replace high-pressure hose.
b) Formation of droplets on the underside of the power steering pump:
The cause of this is often an overfilled reservoir.
NOTE: Before the cover is screwed onto the reservoir. clean the sealing surface of the cover and its support surface on the reservoir.
