Psychonova68 36 #1 Posted February 6, 2020 My transmission has bad axle seals and I noticed a small leak from the input pulley. So I have the transmission on my workbench and noticed that both hubs and the input pulley are welded on, is it mandatory that I take those off or can I push the shafts out from the inside? Also from looking at the various charts the commando 8 should have 3 speed, but mine is a 6 speed(3L+RL &3H+RH). Does this mean that the tractor did not come with this transmission? How should I proceed with this transmission project? Any help is greatly appreciated. 1 Share this post Link to post Share on other sites

Psychonova68 36 #3 Posted February 6, 2020 Nope, they are welded on, initially in the low light in my garage I thought it might be hardened grease until I took a screwdriver to it. 3 Share this post Link to post Share on other sites

LOL yea you are going to need the hubs off if you want to replace seals. id use a small grinder and see what you can do. 1 Share this post Link to post Share on other sites

Small grinder is fine .... you're going to end up needing to split the transmission and replace parts. Not at all difficult. Post whatever pictures you can and there will be several of us that can help you tear into that transmission and get it back to being correct. 2 Share this post Link to post Share on other sites

ebinmaine 67,265 #8 Posted February 6, 2020 I've got an input shaft and maybe a pulley for it Share this post Link to post Share on other sites
stevasaurus 22,706 #9 Posted February 6, 2020 To answer your question, you will not be able to open the trans to free the axles and input shaft with both hubs welded onto the axles. The way you describe the transmission, you would have to, at least, remove the left side hub. In any case, you will have to remove the pulley on the input shaft to get the input gear out. Also, if that is a Command 8, that transmission was added by someone else...not factory. Grind the hubs and pulley to get them off. Save what you can. Don't forget pictures. 3 Share this post Link to post Share on other sites

Do you need to use nickel rod on these hubs to do any repair? 1 Share this post Link to post Share on other sites

pfrederi 17,662 #12 Posted February 6, 2020 Work the left side hub first. Try to grind off the weld and then see if you can pull the hub off. Also start soaking the hitch pin and that looks like it may not want to slide out. Then yuou can split the case remove the left side take the differential apart and hopefully pull the right side axle and hub out together. The right side hub keyway doesn't look good and the weld may have damaged a lot of the axle. That side may be a lost cause. 3 Share this post Link to post Share on other sites

bottjernat1 2,190 #16 Posted February 6, 2020 Hey atleast they couldnt weld worth a poo! LOL Should have seen the 1974 sears i had someone did a bang up job welding on the back of it a hitch to mount a ball. What a mess. but when i got done you never knew the mess was there. The key is just take her easy and think it out! 4 1 Share this post Link to post Share on other sites
Rob R 966 #17 Posted February 6, 2020 My guess is part of the leaking problem you are having is the amount of heat generated with all the globbed on welding damaged the seals! 5 Share this post Link to post Share on other sites

No worries. You'll get it. Three years ago Trina and I didn't know. Well basically anything, about these tractors. We've done a lot of work on them and learned an awful lot. You've got the attention of those with the best of capabilities with the other fellas on this website. 1 Share this post Link to post Share on other sites
The Tuul Crib 7,336 #21 Posted February 6, 2020 The biggest thing is to not get in a hurry because rust can really slow you down! Take your time to grind off the welds. Hubs can be replaced if need be. Save the axles! 1 Share this post Link to post Share on other sites
Psychonova68 36 #22 Posted February 6, 2020 Got the left hub off, actually wasn't too bad, hitch pin also came out with ease. Going to see if I can get the other hub off. Do the pulley and brake come off with a puller or what? 2 2 Share this post Link to post Share on other sites
pfrederi 17,662 #23 Posted February 6, 2020 Remove the bolt and a puller will get the brake drum off Share this post Link to post Share on other sites
bottjernat1 2,190 #24 Posted February 6, 2020 This is what i fixed it was welded everywhere also not in the photo it was welded from underneath. But i got it all back to original enough to mount the 3 point hitch. Took my time. It was a 1974 sears ss16. Ive seen alot worse stuff on some horses. 1 Share this post Link to post Share on other sites

Look at the end of the shaft and you'll see aqui way there they will be a set screw down through the middle of the pulley. Brake drum should have a bolt in the end but I have also seen a brake drum with a set screw on the key. Share this post Link to post Share on other sites
