Default Need a John Deere MC Final Drive

Hey all,

I busted the case of the left side final drive on my MC while i was pushing dirt. I've been searching craigslist and ebay for a final to no avail, does anyone know of a good JD-specific parts website/boneyard?

thanks,

connor

I have a MC to restore with one final drive not working. I think that they were light and not strong like a caterpillar. Good luck.

they're known to have weak finals. If you look at the newer models of JD crawlers like the 440, 1010 etc you can see lots of re-enforcing webbing in the casting.

Con-rad; I had the same thing happen to me about 30 years ago on that same MC type tractor. What I did was take it all apart and lay the casting on the welding table, Grind the cracks and broken edges, put back together and clamp real good together and to welding table, Do some preheat with gas thorch and weld about one inch at a time in maybe three places then wait about 1/2 Hr. do some more preheat and weld about one In. In about three more places. Do this till all is welded, Overlap a bit on the welds. Take your time, Don`t get in hurry, It mite take 1/2 a day to get this done, Then turn part over and start over again, Grind joints, Take your time, Another 1/2 day or so. this time between welding , Put a couple of heat lamps on the part, real close, move lamps, do some welding. Do this till all is welded, kept the heatlamps on for 2 to 3 Hr. then back off a bit. then wait over night with heat on ,let cool very slowly and grind smooth on inside where needed, I would not grind outside much. Use a good rod and penetrate good. Have fun. Roger Weinhold AKA Charlie 1925 Check my profile

Thanks Ed, i'll see what he has.

Do you guys know how to take the hub/sprocket off of the drive shaft? i've been cranking on it with a puller and hitting it with a torch and beating it with a hammer to no avail. Judging by my parts manual, there shouldn't be anything else holding it on...

thanks,

conrad

Con-rad; You just came in contact with a 4 letter word . ( RUST ) or that other word witch is ( Intergrandalar carrostion ). That tractor is about 50 + or - years old , It`s had a long time to do what ever it did. About all one can do is what you are doing, plus some good penitrating oil like (Kraoil )
l don`t know what the factor is between years rusting and getting something lose, Hopefully only a day or two, Kept the puller on with heat and oil and wait . Good luck.
