I need to replace the power steering pump not because its leaking but the power assist has gradually lowered. There are two part numbers in the GMCMI
Parts Exchange for each supplier. It is original has served well for over 40 years. I did a search of Forum and did not find any suggested part number
but a suggestion that the motorhome one is not the same as the Torondo. I would like to get a new one rather that take a chance on a rebuild. Our
coach is a 1976.

Al,

It's been quite a while, but I found the Saginaw pump VERY easy to
"rebuild" with an inexpensive kit. You may want to try that -- the R&R are
the worst part of the job! :-)

If you get a replacement pump, insure it is the same thickness. A slightly thicker one may interfere with an alternator bracket bolt on the head.
That may require removal of the new pump, shaving the bolt head, and then re-assembling that puzzle of PS mounting brackets. Also, don't forget the
hidden washer, number 10 on the parts breakdown page (16-19 in my parts book). Without it the pulleys will not be straight, and thrown belts may be
in your life.

Also make sure your problem isn't a clogging filter. (If you haven't
already.)

Al was a very early installer of my electric wiper kit, so he doesn't have
the OEM filter tube (I guess he might have installed an inline filter
though).

Need to address the shaft as it is either a Keyed or press on.
To get the correct one, you can contact us or gamble on getting the correct.

There has been an in line filter on almost as long as the electric wiper system that is still working very well. The oil looks good and of course
full. It couldn't be anything as obvious as a clogged filter !! I couldn't be that lucky. I'll check it and replace it anyway. The oil has been
changed three or four times including when a Dave Lenzi steering box went on about six years ago.

Thanks for the replies.

Also be sure that the one you get has the reservoir properly clocked. I had to return one to Rock Auto and you get to pay the shipping. I did not
pay attention to the picture when I ordered. They had the right one and the wrong one. I just replaced all that when I did the timing chain.

When we ship a wrong one we pay the freight both ways.

Yes Jim I should have ordered it from you. Everything I have ordered from you has been exactly what it is supposed to be and worked and designed.

Thanks

In my research/reading this morning I discovered there is an internal filter as well. I suspect that my also be part or all of the problem.

I'll just finish this off by saying the power steering pump and tank were replaced this morning. It took a lot of research to get the right parts
mainly because some NAPA numbers are different between the US and Canada. The correct pump was found by cross referencing with the original GM part
number. Had to order the tank from Summit Racing. The pump was NAPA (Cdn ??) 732015 and the tank was Summit Racing 19-7074B5B. Another delay was
getting an appointment during the pandemic when some businesses are having trouble finding enough employees.

In the end it is now done.

Couldn’t you use an updated version with a remote reservoir, would give you the option for more volume and maybe in inline cooler? Just curious
 
You could use a remote version if you could find one that fits and figure where to locate the reservoir. For a couple of pieces of hose you could
install a cooler as well.
