Picked up a Allis Chalmers 616 Special over the weekend. It will back up slowly but will not go forward. Belts appear to be on correct. This is a manual transmission. Runs pretty well, not sure what the problem is. Any ideas guysimagesCASGO4SA.jpg

Looks like a good pickup. I would say to purge it but it'd not a hydro. I have no idea

Clean the brake. Ive seen them hang up. Take it apart, clean and sand the disc. Make sure that all is free and adjust it. Then try it. Brakes tend to be stronger going forward. That may be why it works in reverse. Adjust the belt tension too. I hope that it is one of these simple things.  Good Luck, Rick

Thanks, will try that. I'm hoping for a simple problem but you never know. As you can see it's still on the trailer, waiting for a little warmer weather. :(

If it was a brake problem wouldn't you hear the engine bog down when trying to go in either direction ?

I'd look to see if the input pulley has come loose on the transmission.  If it is tight, jack the rear end & watch the wheels while spinning the pulley.  While it is in the air, have you sheared an axle key?
