DODGE SPRINTER POWER STEERING PUMP REPLACEMENT

[sprinter.motors]

My DIY video on replacing the power steering pump. Used Chinese cheap pump - worked well
Also replaced upper and lower power steering hoses, common places of leaks.

Any reason your DIY video is not applicable to all NVC3 branding (Dodge, Freightliner and Mercedes) and engine models (OM642, OM646 and OM651)?

Applicable to NCV3 family powered with OM642 engines only!

Sorry this guy FAILED a basic trade test.

Certainly NOT to our standard of repair at Linden . The big mistake made which puts PAS pump life in jeopardy .
Does anyone know what it was?

The steering rack and pion didn’t get flushed. He’s adding new fluid in with the old.

Are you sure mister? I was replacing the lower PS rack hose, didn't film that - all fluid was flashed out of the steering rack and PS radiator as well.

Thank you for commenting!

No. there is a procedure to follow to purge out the rack, (in this case) and the lines.
Plus inspect the reservoir for crap retention.
Whether its a $175 PAS pump or a $5000 one on Poclain, or Caterpillar the procedure is ALWAYS the same.
It wasn't done on the video nor even mentioned .
Trade question?
Do PAS systems filter on the suction or return line?
Dennis

 

[CJPJ]

Neither the suction or return line filter on the closed power-assist steering system.

 

[lindenengineering]

Normally filtration takes place on the return.
Only you might find a course mesh on the suction.
And the filter is where ?

Show me where it says in WIS?
I disconnected both PS lines from a rack. Turned steering few times.
Gathered 1 quart of PS fluid in total - which is capacity of PS system.

What is the purpose of these comments?
Make a better video if you know better than me.

The filter is Nowhere because it doesn't exist in Sprinter Vans.

First are you sure.
Have you looked inside the reservoir with an endoscope to verify the interior for cleanliness /residual contamination and the existence of an integral filter?

Yes, I've looked with a microscope. Have found residual contamination but haven't found a filter.

So what does that tell you?

I also like the Socratic method of teaching. But once the information is finally extracted, this thread will require much editing to make it useful for the DIY write-ups!

This divulges that Dennis
