Hi guys. I have an 855 Cummins 400 horse. The power steering pump is getting weak. Are they all the same on the 855 models? Maybe someone can help identify mine and suggest where to get one. Attached is a picture of the tag. Any help would be appreciated. Thank you
What does it power? Often it's unique to the truck... IE pump in a Ford L9000 different than in a S25xx International.
Here is a link to Vickers data sheet for their PS pumps. https://www.pmchydraulics.com/content/files/brochures/datasheets/pumps/eaton/eaton%20v10%20and%20v20.pdf
V20F looks like a Vickers number.
It is a 1985 diamond Rio
Thank you
Thank you
A Vickers 10 was standard--20 was normally used for sever/heavier steer axles. Then again trucks spec'd with B model Cats had a tendency to always be fitted with 20's.
Here's another sounce for service data: https://www.psifp.com/customer/docs...-guide-vane-type-single-pump-m2004s-en-us.pdf
I'll have to see what my n14 has, went from a single axle to a twin steer and runs the twin very well
