We're just looking at owner manual page pics....no actual vehicle. What you see above is what we get to guess at.

I just used a magnifying glass and I think you are right, there is a cable heading to the drivers left that appears to connect to the lever.

I have not seen any pictures showing what the heater control valves looked like. I do know it is NOTHING like the heater control valve in my coach.

YES! The manual does list the windshield wipers could be either electric or hydraulic. The manual describes the different switches used for each type. However my coach has the electric type of wipers but the controls as described in the manual don't match mine

The two hoses definitely head down towards the power steering pump area. I think you hit it, the pictures shows the control unit for hydraulic wipers.

I'll look at the Chevy parts manuals tonight for windshield wipers.

Thanks!

Brad

Bingo! But when the chassis is shipped there are no wipers. Just a bare frame sled with powertrain, steering column and a wooden box with loose parts as a driver seat. Wipers were added by coach builder. Some GM parts and many not. We never had a hydraulic wiper system for the P-chassis.

The fuel priming pump on an Isuzu is a small piston pump on the side of the high pressure injector pump. It is about 1 1/4" in dia. with about a 3" stroke.

I have no clue what that thing is but judging from the pictures the hoses look pretty big for fuel hoses and also if it was some hydraulic wiper control I really don't think it would need hoses and flow that big.

It will be interesting to find out what it is.

Cheers, Dan

Just guessing, maybe it is some kind of oil pump booster. I had similar looking doohickey on my boat. It had a Kubota (Universal) diesel 4 cyl. You gave it a few squeezes prior to starting the engine. It prelubed the top end of the engine.

I like the idea in Post #2. Many Boats and Motorized RVs have economizers (heat exchangers) built into the water heaters. They use engine coolant to keep the water heater hot.
Why would they use such a stange looking spool valve? Lots of different manufacturers and lots of plumbing choices.

Brad,

I'll go back to my original thought in post #2. Take a look at the attached file.

I think, in the long run, you will have to trace these hoses for the group.

Please let us know what they turn out to be.

Chris

That's a Trico "Hydro Wipe" wiper motor. It was used extensively on Ford products in the '60s.

I think you nailed it! Being a Ford product (or should I say used on Fords) actually makes sense because the Argosy uses the dash heater control from a 73 Mustang and the vacuum actuators for the A/C-heater system are Ford vacuum actuators.

Check out: 1969 Lincoln Continental Coupe Hydraulic Windshield Wiper Motor

The contraption in this auction is the same as shown in the owners manual. It's certainly looks a lot different when you can see the whole thing. Kind of like an ice burg, most of it is hidden from sight!

Thanks all for helping me track down the unknown device.

Brad

I wish I could trace the lines! The pictures in question are just images from my Argosy owners manual. I wanted to find out just what it was. Now that I know it is a hydraulic wiper motor I'm glad my Argosy didn't come with that option

When I first read your post the picture you included didn't show up, not sure why but I didn't see it until after I posted the ebay auction listing.

Thanks for the ID!

Rich,

Based on your comments I gather you have or have had some involvement with the P30 chassis. Does this mean the motorhome owners on this forum could consider you our in house expert on the P30 chassis?

Thanks for your help.

Brad

Yes, I was involved with the commercial version of the P30...and just a little bit with the MH version. It was15 years ago and I no longer have access to paper manuals, as I am a field rep. The old manuals were not converted and put online, since we sold the business and responsibility for the chassis a long time ago.

Soooo, I'm only an "expert" to the ability of my aging brain's retention of 15 year old info. I recall some stuff, but haven't touched one for about 12 years. If I can contribute I will, but most of you owner DIYers probably have more info than I.
