tmix61 81 #1 Posted January 3, 2023 (edited) Okay guys a little help this is the VIN on my tractor what does it all mean? And what kind of rear end is in it I have a problem with it where would I find manual to take it apart. From a couple of people that looked at the crack something got wedged between the gear and the case and pushed it out might be a bolt that broke off and got caught between the rain gear and I pushed it open.

oliver2-44 9,929 #6 Posted January 3, 2023 @tmix61 This should be the manual for your transmission Transmission Hydro Sundstrand SM #492-4206.pdf Also if you search for 90-1137 you will find 50 threads referencing that transmission. Sort through them and there are some good rebuild ones 1 1 Share this post Link to post Share on other sites

daveoman1966 3,762 #12 Posted January 3, 2023 This 'CRACK' is beyond repair...unless you can weld cast iron. (WYSIWYG)What you see above is the extent of the internal gears. I can send you a replacement trans case side...$60 + ship. The differential comes apart, of course. The LEFT two gears just slide off/on the shaft. The center gear is a welded/pressed assembly and doesn't come apart. This all makes it very easy to swap over gears.. 1 1 Share this post Link to post Share on other sites

Would you happen to know the grease seals number for the axles and the gasket to put the transmission back together or where would I pick them up thank you very much for the help I will let you know if I need that side of the case 2 Share this post Link to post Share on other sites

Oh I think I understand the axle seals will be in that kit and so will the old rings for the hydraulic where it mounts to the top of the rear end am I right? Thank you for your time 1 Share this post Link to post Share on other sites
pacer 3,174 #18 Posted January 3, 2023 (edited) A reminder --- those 4 nuts exposed on the big gear in the pic are the ones that caused your problem, yours were probably 5/16 on about a 3-3 1/2" bolt and one of the nuts broke off. The ones in the pic appear to have the 3/8" pinch nuts/bolts. You'll want to either bore yours out to the 3/8 or get a gear that has them. The big gasket is probably still NLA (no longer available) That $60 case @daveoman1966 is offering is a good price, and he dont sell anything that isnt in excellent condition.

stevasaurus 22,914 #19 Posted January 3, 2023 @daveoman1966 is the guru on the hydros. I would listen to him on this case. BTW, I know nothing about "D's". 1 1 Share this post Link to post Share on other sites

Does that kit give me all the o-rings for the hydraulic tubes on top of the transmission and the wheel seals? Edited January 3, 2023 by tmix61 1 Share this post Link to post Share on other sites
daveoman1966 3,762 #21 Posted January 3, 2023 (edited) I don't think the kit includes the 2 axle seals. Seals are OEM #6449...find them on Ebay. The OEM Trans Gasket is # 5999. Ebay again...MAYBE. You may find this gasket on-line, but not sure...may be outdated. If so, one can be made using either case side as a template. Get the GASKET 5999 and SEALS 6449 Here: https://wheelhorsepartsandmore.com/product/wheel-horse-5999-transmission-gasket/ Edited January 3, 2023 by daveoman1966 Share this post Link to post Share on other sites
953 nut 56,177 #22 Posted January 3, 2023 Lowell @wheelhorseman has the case gasket and others as well as the axle seals you need. Give them a call. https://wheelhorsepartsandmore.com/product/wheel-horse-5999-transmission-gasket/ 1 Share this post Link to post Share on other sites
