1250 Hydraulic oil change
 

Looking to change the hydraulic oil on my recently acquired 1250. I know, Hytran, 7 quarts, I got that part drilled into my head in the little reading I have done.

So three questions
1) Gaskets - What do I need and where can I get them?
2) Filter - what do I need and where can I get it
3) Assuming I find a bunch of gunk when I pull the cover off what is the proper cleaning procedure?

Anything else I should know when doing this is appreciated as well.

1) Gaskets - What do I need and where can I get them?
Rear Cover gasket: Your local dealer or one of our sponsors located at the top of the page.
2) Filter - what do I need and where can I get it
You can get a Hydro filter at your local dealer or NAPA: Here is a link with the numbers: http://www.onlycubcadets.net/forum/showthread.php?t=12
3) Assuming I find a bunch of gunk when I pull the cover off what is the proper cleaning procedure?
Raise the front end higher than the rear to let it drain good, then use some carb cleaner and some lint free paper towels or rags and just reach in and get the goop out.

You can get a piece of gasket material at a local auto parts store and cut yourself a new gasket, probably as cheap to just go to cub dealer and buy one...but you may not have a local shop.

Dwayne made some good points, however, my 129 rear end was extremely dirty, I am guessing it had close to a 1/2" of sludge in the bottom. I used a stiff bristle parts brush and diesel fuel for the initial clean up/ sludge removal. Then I finished it by wiping it out with microfiber towels dampened with laquer thinner, it removed all traces of the diesel and sludge and it dries almost instantly. The carb cleaner should work equally as well, I just happpened to have a gallon of laquer thinner on hand, so I used that. Like Dwayne pointed out, put the front end up on car ramps or jack stands, makes cleaning/ draining all the junk out of there much easier.

Oh, if I recall, the hydro filter can be obtained at most auto parts stores, have them look up a Wix 51410....I will check to make sure I quoted the right number, that is off top of my head, if I am in error, I will edit and change it! The wix number has been corrected!

Thanks guys, I am going to tackle it this weekend if I can find the gaskets, will let you know if I hit any snags. One more question, I just notice that my hydraulic lifted deck is sitting on the floor after the tractor does not run for a couple of days. Is this normal or indicative of a problem?

That's pretty normal, and likely caused by internal leakage in the control valve.

After you clean and replace the filter you "might" have to do an additional filter change after some run time, due to loosening particals that you can't reach to wipe out. You will know when if you seem to start to loose power/speed or reaction seems sluggish. :TwoCents:

So,

Does anyone use anything other than hydrotrans? I was looking at the autoparts store and they had a hydraulic fluid which says "meets IH B-6" and it's $9.95 gallon. O' Rilley's autoparts.

I was thinking it might be good to throw it in for 50 hours and then do a change back to the CC stuff.. if it is superior. I'm assumming there will be lots of gunk in the bottom of mine.

In my opinion, hytran is the only way to go. Its a little pricey, but you pay for what you get:beerchug:

Well said! :ThumbsUp:

Yea put it's not available easily ..

TSC carries a semi-synthetic hydrotran stuff. WILL That work? It's $13/quart.
