2009 Cummins ISL power steering issue

Has anyone else had a seal failure in their power steering pump that allowed engine oil to get into the power steering system and over fill the power steering reservoir?

I'd consider that very odd. Thinking of my system and the p/s pump mounting to the air compressor ; the engine oil the p/s pump seal is exposed to is splash from the compressor crankshaft , and the internal p/s pump fluid is under pressure , so I'd expect fluid to go into the engine oil rather than engine oil into the p/s reservoir .

Air compressors are pressure fed with engine oil, so it is possable.

Yes , but the whole of the compressor crankcase isn't pressurized , so only splash from the compressor rods and mains , gets to the p/s pump seal .
Unless the whole engine vent system isn't functioning , then one would expect , engine crankshaft main seals would be the first to leak.

Power Steering Reservoir filter - NOT

Freightliner says to replace the power steering reservoir filter whenever changing the fluid. Freightliner says the filter is NOT available. Say what????? Yup, not available but it turns out it's because they want you to update to their new reservoir canister and filter system. Only problem is that it's not available the they don't know when it will be.



What a way to run a business!!!!

I’ve had good luck using EBay to cross filter #s...better than NAPA. Try searching EBay with the filter # you have/need.

One comment a little off track.... if you have a dirty air filter, and your going up hill, the turbo is screaming for air.... and can suck the clean air side into a vacuum... usually the air to the air compressor if fed from this clean air side between the air filter and the turbo....

So think about this.... if the turbo drags the system into a vacuum from the dirty air filter and the air compressor IS NOT pumping air.... that means that the intake valves are held open by the governor... all this make sense so far...

So here's the next step... its possible for the vacuum to pull lube oil up past the rings in the compressor and put some oil in the head of the compressor.... this in it's self is not a big problem if the compressor is in good shape.... but the as the compressor starts to run it now pushes that oil into the dryer where it can cause problems... and also if the supply line from the compressor to the dryer is not large enough... or has lots of elbows....some of this oil can cake on the tube/hose and cause a restriction.... thus leading to more problems...

I could go on with where this all goes... but the key here... is that the sensor... you know the little plastic deal that says how bad the filter is clogged... that's pulled open by vacuum... so watch the air filter and keep it clean...

Haven’t seen that in 25+ years. Most get their air at the intake after the turbo and before the EGR tube.

Correct. That way the air is not only clean, but "pressurized" by the turbo and cooled by the CAC. Makes the compressor work easier.
