scottscott 0 #1 Posted January 19, 2014 Hello all. New to the forum. I have a 1981 GT 2500. The high-low shift fork in the transmission broke. It's the 5086 transmission. I know that I can get the part, but I have something else in mind. I want to know if the transmission off of a c85 Wheel Horse will work on my gt2500. The c85 transmission number is 103916. what are the differences between these two transmissions? Any help is greatly appreciated. Scott Share this post Link to post Share on other sites
Sparky-(Admin) 21,415 #2 Posted January 19, 2014 Its a straight swap. The C-85 has the "Heavier duty" tranny. It'll have 1 1/8" axles with 8 pinions whereas your GT-2500 has the 1" axles and 4 pinions. So all the differences are inside the units.

scottscott 0 #5 Posted January 20, 2014 Thanks Sparky. So, here is my situation. My gt2500 has got a b&s engine. It also has a snow blade i use in the winter. Snow blade is good. Engine not so good. Hard to start.I use a whole can of starting fluid and battery jumper every time just to get it started. Should i buy the c85 for $350 and use its engine and rear end for my gt2500?

WH nut 553 #6 Posted January 20, 2014 Sounds like time for a complete replacement. Share this post Link to post Share on other sites

I had a C-111 one time and I think they were the same too - yet later models, like some 312-8 tractors, even with more hp had 1 inch axles and 4 pinion trannys. Thanks Sparky.

IMHO - if you buy the C-85, I'd use it as it and part with the GT2500. No mods required, no moving parts from one tractor to the next. I would also think the electrical would be different between the two tractors. With the C-85's stronger tranny, i think it would be no problem bolting in another engine down the road - but everything you have, i.e. implements, for the GT2500 should fit the C-85. 1 Share this post Link to post Share on other sites

I agree, if the C-85 is a running machine then run it. Save the GT-2500 as the parts machine or a re-build project for down the road. Mike......... Share this post Link to post Share on other sites

scottscott 0 #11 Posted January 22, 2014 Sound advice. Thanks guys. I did go a totally different route than i set out for; I bought a hydrostatic. The price was great. Thanks for the advice from everybody! Share this post Link to post Share on other sites
scottscott 0 #12 Posted January 22, 2014 Yes, leeave96,i thought the gt would have the bigger axles also. Thats why i was thinking i should put everything on the gt. Was thinking it would be heavier duty& it sure looks like it sits higher. Less frame drag in deeper snow? Even though i bought the cub, i still like the wheelhorse. Having it for 8 years, really good solid tractor & i love the snow blade tilt control being mounted on the handle. Loved the low range gears too! Share this post Link to post Share on other sites
