The van still has the normal sized reservoir at the pump, just has the additional capacity of the remote reservoir and hose. If anything the van has more fluid available.So here’s a thought: in the vans, the fluid reservoir is connected to the housing via a length of tubing. I wonder if the truck style housing helps the pump stay better lubricated because the fluid is right there.
Maybe I should source one from a truck?
Early in my career at The Bus Company, we had pallets of Vickers (V20?) power steering pumps that had been mistakenly ordered--or mistakenly packaged 'n' shipped.
Anyway, all these pumps were brand-new...but set up for use in an application that turned the rotor the other direction than the Detroit Diesel 6V92 was going to spin them. (PS, air compressor, and alternator were all gear-driven off the back of the engine. Alternator was rated for something like 150 amps at 27 volts, but weighed 80 pounds and was oil-cooled, 'cause it was expected to push 150 amps all day long.)
That's the first time I'd ever been "inside" a PS pump. A bunch of us were tasked with pulling the pumps apart, flipping the cam plate/rotor housing upside-down, and putting 'em back together. We'd occasionally have to do the same thing to a few pumps after that, but not pallet loads of 'em. The housing had marks cast-in that showed the rotation direction they were intended for, but it's been so long I wouldn't know 'em if I saw 'em.
Flipping the guts of those big Bus PS pumps is the only time I've had PS pumps apart beyond unscrewing the pressure valving from the back side.
Gonna have to do a Saginaw someday.
50DN Delco. The 12V alternators had a different-color serial number tag than the 24V units. We mostly--but not always--used 24V.That sounds like loads of fun! First I have heard of an oil cooled alternator.
@Schurkey & @BVRPLZR The outside of the rotor only touches oil. The rotor in the first picture has a fast lathe cut, each line is even.The side of the rotor can show wear. The picture of the cam ring shows wear. You would also check the pressure plate and thrust plate for wear. Harder to see, the leading edge of the vanes probably have wear in that pump.
