HEMTT steering pump specs

[plowboy]

Does anyone have the specs for the pump mounted on the outside drive on the rear of a HEMTT 8V92? I believe that it is the steering pump. Also, does anyone have one or more to sell, including the drive?

I located specs which, if accurate, indicate that it is 9 gpm.

Your talking about mounted to the rear of the transfer case? The PLS trucks have an emergency override steer pump there


The pumps on the #3 axle and sometimes #4 are just heavy duty oil pumps for heavy haul like the 917s have hooked to them. They are about 9gpm

It is mounted on the rear of the left-hand camshaft.

I found the Vickers spec number somewhere yesterday and it looks up to be 9 gpm. It has now occurred to me that I may or may not have considered RPM when I looked that up.

I need to get it out and call Baum or someone and see if I can convert it to a two section pump. I need a 3 gpm circuit and one about 9 gpm. I was just going to use two pumps but if I can reconfigure the pump to double it will be easier than installing another drive on the engine case.

Alternatively, I could belt drive a pump for the 3 gpm section.

I'll have to look, but I believe my M985 has 2 pumps on the back of the engine. One for steer and one for crane/winch. They plumb off of the same tank and are both continuous run design.

that looks like the same one on my first truck, 96 freightliner. there will be a part number on the case of that pump, I will go get a pic of a different pump, (like same, but different) for locating the pn. Then google is your friend.

The pn will be on the flat, if no tag, possibly in dot matrix print.
