Reservoir for Jacks

For 13 years I assumed that the large canister next to the surge tank in the engine bay of my 2005 Allegro Bus was for my hydraulic jacks. I've checked it frequently and it never wavered on the level. It is labeled for 15/40wt oil. I thought that odd, but this is my first Diesel. Turns out that that canister is for the power steering, nothing to do with the jacks.

So, it begs the question now that I have a leaking front jack: Where is the jack reservoir, and what kind of fluid does it require? Doesn't seem to be near the pump. (BTW My slides are not hydraulic.)

I'd appreciate some help...

Mine is on top of the pump, far rear on the curb side. Check your manual or maybe the pump itself, for the fluid. I'd assume jack oil, but I'd check first.

I don't know about the '05 Bus, but on both Tiffins I have owned the HWH reservoir is behind the mess of hoses where the pump is located. It's a real PITA to get to and you almost have to use a mirror or a stick to check the level.

From the HWH Manual:
FLUID: HWH Specialty Hydraulic Oil is recommended. In an
emergency emergency Dexron automatic transmission fluid can be used.
Dexron automatic transmission fluid contains red dye and can cause staining
should a leak occur.
DO NOT USE: Do not use brake fluid or hydraulic jack fluid.
Use of these can damage seals.

HWH hydraulic fluid is sold at camping world. Probably from Amazon but have not confirmed if they sell it.

Lt Dan is probably right, last month we were trying to find it on a Red with a Freightliner chassis and couldn't find it and on our row was a Phaeton with a Freightliner chassis and the owner confirmed what Lt Dan said. Our camping friend reached behind all those hoses and sure enough that was where they hid the tank. Seemingly impossible to see or svc. Guy we talked to said he had to use a mirror and a funnel with a tube to fill it. Dave

HWH fluid is clear transmission fluid. Clear so as to be non staining in the case of a leak. Available st Camping World and Amazon. Dex 3 ATF from any auto parts store can be used as well, albeit not non staining.

Okay thanks all for your input. I've just come in from getting greasy and looking all over the pump and anywhere else I could look...no reservoir. Of course it's there, but eluding me. Next step is a call to Tiffin service on Monday. I'll post a follow up for anyone interested.
