Super A help!

Hello,

Currently in the process of restoring a 48 SA and hit a small stumbling block. Unable to turn the rear wheels. It did this while completely separated from the engine and front end. Shifter is in neutral, we reassembled the engine but can only turn crank by hand if clutch pedal is down. Can move shifter while pushing in clutch but the movement is erratic and doesn't line up with shifter grid. No movement at all from rear wheels. I've done a bit of homework and am wondering if it could be stuck in 2 gears or if the input shaft is jammed. In either case, or if its something else entirely, i'm not sure how to proceed. Would appreciate any advice anyone can offer.

Thanks in advance.

Could be stuck in 2 gear or if it is where it is cold could have water in the transmission and or rear end that is now ice and that will lock one up also

Did you lock the brakes? They be rusted to the drum.

Take the top off of the transmission and look inside and look at the shifter rails. You'll find the problem. Post back if you still are
unsure.

Update: Rear end had a ton of water in it. Removed all the drain plugs (took me a while to find the final drive plugs) and put heat to the rear end and removed everything. Wheels spin freely now. Only issue i'm still having is the tractor won't find first gear. Goes easily into all the rest. Am going to try taking the transmission cover off and see what we can find.

As Old pointed out, the ice problem seems to be pretty common around here for YT members in cold climates. Surprising, how strong a block of ice can be. I had an M freeze up (literally) last winter and had to wait until warm weather before I drained a couple of gallons of water out of the differential.

Also, I would recommend taking the pans off the final drives. Then you can clean them out and inspect the bull gear. You'll need new gaskets, of course.

Yes, there are no drains on the final drives. The pans must be removed to get all the old oil out.
