Hydraulic Fluid Reservoir
Hi,
I have a 2002 Itasca Horizon. This MH is built on a Freightliner XC chassis with a Cummins ISB engine. Near the top of the right side of the radiator (viewed from the rear) is a Hydraulic Fluid Reservoir. The return fitting at the tank is cracked and leaking. I've patched the fitting with some epoxy, but don't expect it is a permanent fix. 2 questions: what is the hydraulic fluid in the reservoir used for and is this an available part?
Thanks,
Albert

As I mentioned I have repaired the leak, but I'll get a picture of the tank as soon as the wind calms down enough to allow the MH cover to be opened up.

Power steering reservoir. If the level gets down you could get air in the lines..Section 46 in the FTL maintenance manual. Complete tank should be available from Freightliner.

One thing to check is make sure that it is hydraulic fluid and not engine oil. My 2008 Thor on the XC chassis was converted to engine oil. I called Thor to confirm that it actually was changed to engine oil. There is a sticker on my tank that says use 15w40 engine oil. I have the side radiator and the system runs the power steering and the fan for the radiator cooling.

Albert,
Your '02 Horizon is very similar to ours and a zillion others with that rear style Freightliner setup. And, if your system looks just what what's in the picture, then that tank you're talking about IS the power steering reservoir. I have also broke or cracked that same fitting on mine. I repaired with a special glue/catylist and, it's been like that now for over a couple of years. I'd eventually, like to replace that fitting or, maybe even the tank.
Anyway, see if yours looks like ours.
Scott

Mine looks exactly like yours. I've made a similar repair so maybe I'll leave it as is and keep an eye on it. I talked to the local Freightliner parts department and the guy wasn't sure if they had the part. I need to take the picture and go talk to them about it.

Forgot to mention that my fitting broke off completely. I found a poly elbow at True Value that was just slightly larger than opening. The side wall thickness is very thin so I was only able to tap a couple of threads into the tank. I used some construction glue, the same as I have used to reattach the metal tabs to several of the fiberglass panels on the MH to firmly attach the elbow to the tank. I did that last fall and no seepage so far.

On AccessFreightliner--The Hydraulic tank on my XCS chassis looks the same, part number is A14-13336-000 RESERVOIR ASSY-HYD, 2.5QT, 2PORT -
But that is only the tank, the 2 fittings, one 1/2 and the other 3/4 inch are shown separate w/o part numbers... This may help the part guy at FTL identify the fittings.
When I flush the hydraulic system, it puts a lot of stress on that fitting to remove the hose, probably just a matter of time....

Thanks for the info. I'll call the local Freightliner parts department and see what they have to say.

Hydraulic Fluid Reservoir - follow-up
The part # provided by Hooligan in a previous message (A14-13336-000) is a valid Freightliner #. Much to my surprise Albuquerque Freightliner had the tank in stock. It comes with both fittings attached and includes the vent at the top. You will have to save the fill cap from the old tank. It is a bit pricey with a list price of $236.38 (COD price was $326.92). Now to see if I can get it installed without breaking a fitting ;-)

AccessFreightliner is pretty handy at times. Helps with part numbers and often the drawings help with disassembly. Free signup with Freightliner. Based on your vin#, shows the parts that were on your chassis when it left Freightliner. www.AccessFreightliner.com
That reservoir is pricey!!!

One question I have is how often should you change the power steering fluid and the filter? My filter was changed when Freighliner recalled it several years ago.
What is the best way to drain the fluid if changing is necessary?

My manual calls for check levels every 6 months and change fluid at 24 months. (No filter)-- Newer manuals show 12 month interval for change filter and fluid. Some use DEXRON III some use motor oil. The maintenance manual gives procedures, it's messy. See Section 46. https://secure.freightliner.com/newb...e%20manual.pdf
