Unhappy Leveling system - Help needed

Hi Again,

Today I tried to find out where my problem with the leveling system lies. To make a long story short everything works but the hydraulic oil ends up in the engine.

There is no visual leaks anywere in the system (pump, lines, valve, nitro bladders or dampers) and as long as the engine is running the hydraulic oil level stays constant and there is a slow but steady oil return in the reservoir. Once I shut the engine of the reservoir is emptied and the engine oil level goes up.

Im assuming that somehow the hydraulic pump leaks and the leakage is aggrevated when the engins shuts off.

Is there anyone that recognises this problem? Is this a DIY job to fix? Is there a rebuild kit for the pump or do I need replace the whole pump?

Please help me out,

Thumbs up

Thanks Kebowers,

You, Sir, have just saved my day. A new seal cant be all that bad to change or expensive.

Many thanks again,

Mikael Westerberg
