House Separation 350 will not move
I recently purchased my first bulldozer. A JD 350 (straight). Motors runs like a top, the 6 way blade is extremely responsive almost like todays dozer's. the electrical system was non-existent. A new alternator and wiring I have lights and it starts with ease. The previous owner had replaced the reverser so my attitude towards this beautiful machine was extremely optimistic. I have put about 20 hours on it since purchasing a month ago.
Thursday I was cleaning up around the property and reverse started to act up. I was not abusing the machine by any means but it was a hot day and I had run it for a few hours continuously and it is 50 years old. I made my final trip up the hill and i was hearing a clunk. Thinking i was loosing a track i stopped to clean the tracks. Didn't find anything particularly troublesome so i continue. For about 10 feet! and nothing!! No gears at all. I put the blade down to lift myself out of the mud and thats when felt pressure on the floor cover plates. I removed the plates only to find the house seperated about 3?8" on the top of between the transmission and clutch housing. 1 bolt sheered and the stripped out bottom left loose and bottom right still tight. I was able to pull the machine back together by tapping the stripped bolt hole but still have nothing. How much damage did I potentially do and where should I start with my troubleshooting. Did I mention it;s as far from the garage as I can get and in mud 6-8" deep. Perfect!

Re: House Separation 350 will not move
It's possible you stripped the coupling between the reverser and transmission. Unfortunately, no way to repair other than splitting at the trans. With the crawler idling and the reverser in forward, or reverse, if you carefully move the trans shifter like you are trying to put it in gear, do you feel the gears turning in the trans? If not, coupling at least.

I feel and hear a hum as if its trying.
Re: House Separation 350 will not move
Almost certainly the splined coupler as Lavoy suggested. I had to fly in to a bush camp a number of years ago to repair this exact scenario. Loose attachment hardware between transmission and reverser allowing flexing at the joint between the 2. Remove engine, remove reverser, repair stripped attachment hardware and install new coupler providing transmission or reverser shafts have not stripped the splines out.
