Adams94 1,065 #1 Posted March 20, 2017 Went ahead and split it, going to take it to the welding shop and get it beefed up! 3 Share this post Link to post Share on other sites
daveoman1966 3,611 #2 Posted March 20, 2017 (edited) If you have it welded, the heat MAY make the repair itself brittle and subject to further cracking. If the weld repair involves adding on a thicker reinforcement plate, don't weld the plate to the back side as that will alter the required belt length. Better to weld a plate on the inside if that's how you intend to repair it. HOWEVER.... here is a BULLET PROOF method that requires no welding. Use 2 bits of 1 /4 " 2x2 angle iron about 6" long. Cut away the top edge of one piece and fit it into place as in 3rd pic. Transfer hole locations of the transmission case to the angle iron...then drill the two 3/8 holes in angle iron. Test fit to trans case and bolt in using 2 bolts, about 3/8 longer than original. Once in plate and bolted tight, drill 1/8 pilot holes from outside edge...open the up to 3/8. Using 4 bolts with Nylok nuts, bolt the outside corner of the trans plate to the angle iron. Repeat on other side... When done and all bolted together TIGHT,, then you can trim off the excess angle iron with a sawzall....or notl An important part of this is the location of the 2x4 wood block. Jack up the rear of the tractor and let it down again onto this block, just at the front edge of the transmission case. This 'leverage' will 'pinch' closed the broken frame plate, forcing it back to original position. Edited March 20, 2017 by daveoman1966 10 Share this post Link to post Share on other sites
Adams94 1,065 #3 Posted March 21, 2017 I was going to do that but I have one large piece that is missing, I was going to have them build it up on the inside. Thanks for the ideas! Share this post Link to post Share on other sites
Tankman 3,515 #4 Posted March 21, 2017 (edited) Add 1/4" to the trans bolt length to compensate for the material added. Sorry Dave, you already covered that item. Edited March 21, 2017 by Tankman 1 Share this post Link to post Share on other sites
edgro 676 #5 Posted November 23, 2017 this is what I made to fix problem area of C120. I used longer bolts, and the thin piece was for the top set of bolts where there was no factory reinforcement 8 6 Share this post Link to post Share on other sites
ebinmaine 63,157 #6 Posted November 23, 2017 @edgro and @daveoman1966 that's a couple of brilliant repairs there. Nice work. 2 Share this post Link to post Share on other sites
Searcher60 208 #7 Posted November 23, 2017 The original design lasted over 40 years. Get a professional welder to weld it back like it was, and it should last at least another 40 years. A mobile welder could come to you and do the job. 1 Share this post Link to post Share on other sites
Adams94 1,065 #8 Posted November 24, 2017 I split the tractor and took it to a welding shop. They cut off all the old and made it all new. 2 2 Share this post Link to post Share on other sites

Lee1977 6,217 #10 Posted November 24, 2017 Here is the one I did, it was even broke, I just fix it anyway. It's on my 312-8. 6 Share this post Link to post Share on other sites
edgro 676 #11 Posted November 26, 2017 Thanks ebinmaine. That square plate was a pre-cut I found at the local Alro Steel store Last time there they were raising prices, but they gave me the old price, so I got a stack of them to do the rest of the fleet as needed 2 Share this post Link to post Share on other sites

If so, i wonder how old it is??? Edited November 28, 2017 by ohiofarmer 2 Share this post Link to post Share on other sites

edgro 676 #14 Posted November 29, 2017 Good Eye. that's what I thought also. I recently got this tractor for cheap, it had a good sounding non smoking motor. the frame was folded in the middle, broken at the trans mount, and otherwise all cobbled up by PO. Surprisingly enough the trans is pretty well non leaking, including that filter, and It ran and seemed to drive OK. Rather hard to shut the hood with the bent frame. I had a B80 frame in my parts supply that was not broken and was of similar patina (rust), and so thus began another project. I actually did not need the frame repair plate on this, but I put one on anyway, and painted it flat brown to blend in with the color scheme. Yes, the trans filter gas been replaced 3 Share this post Link to post Share on other sites
