This pump was, as you can read on the the erlier posts in the pump subject, sold as a refurbished pump.......well I guess I just got fooled or I have a twisted definition of the word refurbished. The seller seems to think that refurbished is the same thing as a wirebrush and some rattlecan paint.
Well i saw the signs early and as I wait for some other parts i took the opportunity to take it appart to see what condition it´s in.
I had made some research on the Eaton power steering pump on the www and found out that it most probably would be a rotor roller design (the most common), The information about these pumps are quite scarce, but I found some link
Strangers Site . com
Steering rebuilders and Truck parts inc
So from the first link I found out some of the weak spots for these pump to look out for during the teardown.
These where the only markings I could find on the whole pump. But I haven been able to dechiper the code despite the second link I found.
