ebinmaine 67,496 #2 Posted November 23, 2021 Have you gotten into disassembling the transmission to see what broke the axle? Also, what other parts are broken or worn out? Lowell at Wheel Horse Parts and More will be able to supply you with any needed bearings, seals, case gasket. Those axles are not known for breaking so it would be good to figure out exactly why it happened and what's broken around it.. 2 Share this post Link to post Share on other sites

pfrederi 17,739 #5 Posted November 23, 2021 Model number would be important. If it is a 10 hp 1973 no name it may have a Hydro gear or piston to piston. Looks like they each used 2 5961 axles (1" 4 pinion) 1 Share this post Link to post Share on other sites
pfrederi 17,739 #6 Posted November 23, 2021 Looks like WH went cheap with the 10hp in 1972...The Charger 10 then also uses the 1" axle 5961... Earlier Charger 10s had 1-1/8 and 10 pinion... 2 Share this post Link to post Share on other sites
953 nut 55,229 #7 Posted November 23, 2021 After draining the fluid you will need to remove the pump/motor assembly as a unit. There are six bolts, two top ones go all the way through the transaxle case. Once this is done you can lift it up a bit and secure it to the steering wheel. Next you can disconnect linkage and the four bolts that hold the transaxle to the frame. A few more bolts and you will be inside. Lowell at https://wheelhorsepartsandmore.com can fix you up with the gaskets and seals. 3 1 Share this post Link to post Share on other sites
pfrederi 17,739 #8 Posted November 23, 2021 If it is the 5961 axle you are somewhat in luck. it was used in 300 series 8 speeds with 1" axles... 1 Share this post Link to post Share on other sites

daveoman1966 3,751 #10 Posted November 23, 2021 I have detailed overhaul manuals for the Sundstrand automatic tractors. One manual covers the 90-2046 Hydrogear and the other manual is for the Sundstrand Piston-to-Piston models such as 90-1136, 90-1140 etc. Here are both manuals that I prepared in .pdf format MODERATOR: Make these available for download to ALL MEMBERS..

Hover on that for the drop down and click manuals. On the right you should see a list of the categories so click on "Automatic / Hydro" under Transmission, then "Submit a File" Think that should do it. You made them so take the credit for the work done and live forever on RS as it typically shows who presented them on here.

It's hard to believe they broke. This maybe the strongest part on a almost bulletproof tractor. those axles can support up to 50hp with ease 1 1 Share this post Link to post Share on other sites
