A couple of thing s that have been suggested that I would like to reinforce: First, be sure you are using genuine CaseIH HyTran Ultra fluid. I buy mine from my local CaseIH agricultural dealer. Second, buy and use a quality filter. I like Fleetguard, but any of the listed filters are fine.

Here is a link to help you change your HyTran and have a bit of fun doing it. It is important to have a rear cover gasket from Cub Cadet or CaseIH, not try to make something out of silicone or Form-A-Gasket. http://www.ihcubcadet.com/IHCCFAQ/HytranChange.htm

This link talks about HyTran fluid: http://cubfaq.com/hytran.html

All of the filters listed in this link are good: http://cubfaq.com/HydroFilterX.html

Here is the part number for the cover plate gasket: IH-350837-R2

Good luck with your project. Please let us know how it turns out. I
hope you enjoy your 1250 as much as I enjoy mine!

Be well.

Thank you for that part number and also that write up of how to change the fluid, it definitely went over the whole process.

thanks for everyone's help, gonna get that gasket ordered at my cub/case dealer and then get this part of the project over with!

Never use any kind of silicone for a gasket. Silicone's tendency to crumble at the edges and send chunks into oil/hydro pumps make it a terrible alternative to the OEM gasket. More active Cub dealers may have the gasket on hand, but be prepared to order it.

Go to PartsTree.com and plug in your make/model for parts blowups and numbers. Then take those numbers and hit the shops, local or on the net. As mentioned above, OCC sponsors are an excellent source for this kind of stuff.

Also, I agree with the above post about only using CASE/IH Hytran ultra. If you have a CASE dealer in your area, go there for your hydro fluid. It will run cheaper than a Cub Cadet dealer.

thanks...I think my IH/CC dealer must have been out of the gaskets hence his advice to use the "tube" (my used machine had it and I've never seen an issue with it other than trying to clean it off when I did the full drain).

as for Hytran...like I said, we are "JD Green" all around me (family farms typically pick a brand and stick to it and the neighbors buy the used stuff and get married to the brand and it goes on and on such that a brand gets a local monopoly)...

Case/IH is hours away (and you'll find very little "Green" there). I guess my question is whether JD's version of hydro is the same as IH/Case...the older tractors were essentially the same other than color.

I don't agree with "Gasket in a Tube." If a little knob of that stuff gets tangled up in your hydro, you will be splitting the tractor and looking for a good used hydro assembly. It is a good thing they come for sale occasionally, although the freight might be a bit spendy. Even if you have to order that gasket from the sponsors or a CaseIH dealer, it is worth the wait. You won't wreck your hydro while waiting for parts. They don't take that long to get. I am not sure about this, but that gasket could be the same part as the cover gasket for a Farmall Cub.

As for CaseIH Hy-Tran vs. John Deere Hy-Gard; all I want to say is that green paint is very expensive. What has been proven is that Hy-Tran works.

Good luck. Be well.

Yeah, my dealer had it in stock for $8. I didn't have time to go grab it today, but am planning to grab it tomorrow and possibly get this done at some point in the evening.
