Hello. I am new to this forum and am hoping to get some advice from the gurus. I recently picked up a 1960 To35 with the 4Cyl Continental Engine. The tractor is a deluxe model. I got it cheap cuz 3rd gear did not work.
As it turns out 2nd gear also does not really work either. When shifted into 3rd it does nothing. In second it will run for a while but after a few moment is fades out and engine idles but like its in neutral. Shift it back to third and then back to 2nd and she will go for a burst again. No grinding or anything. 1st gear works just fine.
High and low range work fine.
I put the tractor to use right away on a project and everything was working good save for this known problem. I went up a particularly steep hill though and suddenly there was some dull grinding in the transmission. I backed back down and went up the hill in reverse and the grinding went away again. This sounded to me like parts sliding around so i stopped for the day let her cool off and started to do some troubleshooting.
I opened the filler plug on top of the transmission. Drained the fluid. After studying the service manual i suspected that the 3rd and 2nd gear pinions were sliding around on the output shaft. This is exactly what is happening. The snap ring keeper is sheered out and both pinions were slid forward up the shaft far enough that the 3rd gear pinion is free spinning off the splines. I was able to push it back with a long screwdriver and it slides back into place just fine.
I removed quite a bit of metal chunks from the fluid and the drain plug. It looks like the last 1/4" or so of shaft splines that would hold the keeper snap ring in place have been sheared off, but just at the end. The gear slides nicely back into place and feels tight indicating that the rest of the length of the shaft it in good shape, as well as the inside splines of the pinion.
So here is where I am at:
Has anyone else ran into this problem before? Does anyone know what would cause this to happen? Slap-Happy hot rod driver trying to slam shift it?
Output shaft is toast anyway you look at it. So i am thinking if i can get the end of a mig welding torch down in there from the top, Could I Weld the 3rd gear pinion to the shaft? Eventually when i need to rebuild the whole tyranny this would be a problem but with the shaft damage it would need to be replaced anyway so cutting it out in a complete rebuild situation doesn't seem like a big deal to me.
The clutch plates are new but unfortunately one of the 3 fingers on the secondary PTO pressure plate has broken off. So at some point i will need to split the tractor anyhow for a new clutch. I have lots of work to get done this summer that i don't need the PTO for so that can wait. I am not into Hack Fixing! but in this case if i can without causing more damage in the short term it would be very beneficial to my time schedule.
Open to advice. Looking forward to getting to know the community. I love the old 35's i grew up on a apple farm. But moved to town when i was about 16. They had a couple of these with forklift attachments on them, they just have a certain sound that i missed to the 4cyl continentals. This is my first tractor and i can't wait to restore it in a few years after i get my home and shop built.
