Default Fluid in the hyd system in M380

After searching the entire (almost useless) owners manual on my "new to me" M380, I can find no mention of the hydraulic system that runs the engine fan or power steering systems. The fluid appears to be clear like my tractor fluid and is at the proper level, but it would be nice to know what to put in if I ever need to. Does anyone know where to find info on what is required.

thanks,

Jim I'm not sure this will help but here is what I know.....on my 94 the system used 10W 30 motor oil and now with this 99 it calls for Rando HD 32 (Texaco) or equivalent. Its been a while and I may be wrong here but I think Chevron took it over and that's where I was able to buy some. I could only get it in 5 gallon pails. If I was a betting man I'd bet that BB continued with the Rando for a few years and might have used it well into the 2000 model years.

Didn't I read here somewhere that it was hydraulic fluid but was clear because some SOB builder was having problems with leaks and the red color was ruining the carpet and requested the new fluid be clear? Sounds odd I know, but I thought I read that here.

Just changed the hydraulic oil and filters on my M380.

The oil used is "Chevron Rando HD32" (formerly Texaco). I bought a 5 gallon pail at my local Kenworth dealer...about $65.

I also replaced the filters, there are 3. I bought them through Parliament Coach part#2138246.

Here's a complete parts list for servicing the filters of the hydraulic system...

Hydraulic Fan/Steering
-1 spin-on high pressure filter element BB #2122026, Parker #925835, Donaldson #P170073, Baldwin PT8498
-1 “O” Ring for high pressure spin-on filter element (75.87mm ID) BB #2137024, CAT#119-7844
-3 reservoir filter elements BB #2138246, Nelson #83284D, Donaldson #P550698, WIX #57317, Baldwin PT8487

Urgent! make sure you change the "O" ring for high pressure spin-on. Do not reuse the old one.

Thanks for those filter numbers Rob...I'll need to take a closer look at the M380 as I never saw the spin on filter you referenced.

Thanks for the info Guys. You would think that the info would be in the Bluebird manual, but I guess they didn't have room after taking all the room for the AV and security systems info.

Jim (and others) On my coach, the canister filter mounted on the hydraulic fan is a Parker 30P High Pressure Filter assembly. The Parker Nitrile O-ring part number is N92151. When I got the new o-ring from Parker, I took it down to the Caterpillar hose shop in Harrisburg and they were able to match it up with an O-ring that they stock for Cat equipment. The part number is 119-7844 and is printed on the o-ring. The package has number 1 1197844 1008477. So far, this was the least expensive source too. they ran $2.10 apiece. Be sure that you use an o-ring rated for pressures of 2000+ psi. Perhaps BB may have changed systems over the years, but I'd guess that it is still a high pressure canister.
