So we have a 1949 3600 with the 235 its been sitting for about 5 years though it did get drove a bit in 2016 for a mile. We finally bought new exhaust for it so we drove it into the shed under its own power. Then the next day we had to move it so no problem again drove out and back in. Then 2 days later we had everything done and working brakes exhaust etc. We went to pull it out and all of the sudden it would not move after a bit of fiddling we got it to back out but it then would not go forward. So we pulled the service cover off under the clutch and found a mouse nest we blew it out and the clutch peddle felt much better. But it still barley moves and slips really bad it wont slip as bad in reverse it actually stops slipping at times but in 1st it slips hard we drove it like that for a bit to never smelled burning clutch. Do any of you have an idea to what is going on?
I bet I know exactly what the problem is, I've seen this before. That mouse nest is the source of your problem. When you remove the pressure plate you'll find it's stuck in the disengaged position.
When you started the engine, the nesting materials spun out from center and packed in around the fingers of the pressure plate. Every time you pressed the clutch it compressed the fingers and allowed more mouse fodder to pack in and prevent the pressure plate from re-engaging the clutch. Press the clutch in and rev the engine and you've compounded the problem.
At this point the only thing you can do is replace the pressure plate. You wont be able to sufficiently clean the nesting out for the pressure plate to work properly.
Before you start taking stuff apart- - - - -block the clutch pedal down with a piece of 2 X 4 between the seat frame and the pedal, crawl under the truck with a water hose, and flood the bellhousing with a stream of high pressure water with the engine running. A pressure washer would be even better, if you have one available. There's nothing about the clutch system that will be harmed by a high-pressure flush, and you just might dislodge all the junk without having to disassemble anything. If it doesn't work, at least you'll have a very clean clutch assembly to work with when you replace it. Jerry

I flushed mine out with lots of water and it didn't get all the mouse nesting out. I ended up pulling the engine and trans and replace the clutch, it was in bad shape when I got it apart and the throw-out bearing rusted to the transmission input snout, clutch was frozen mid throw.

This happened to my 3600 last fall, i changed the disc and bearing, took the diaphragm p-plate apart (3 small bolts) and cleaned the exploded mouse condo out of it using a hook dental pick and compressed air. Real pia, but worked fine after deglaze of p-plate and flywheel. It don't chatter, buck and jump like it use to. Its a smooth shifter. Good luck with ur project.
btw, i had both pieces of the cover assembly installed prior to construction of the condo. they must enter thru the timing hole.
