716H Reverse but no Forward

Recommended Posts

Just bought me a clean 716H,..cleaned carb and it started right up and sounds good. The thing will climb a wall in Reverse but nothing in Forward. The tractor has been sitting for 4 or 5 years. Any ideas would be great. Thanks.. Dennis

Just checked bypass valves and one does appear to be stuck down because of some rust on the top of it. What am I going to get into when I remove the valve to try to free it up. Sprayed it with WD for now and letting it soak.

Not a lot of magic. Just unscrew them and apply WD40 liberally to get the pin free. Roy had a thread on taking them apart and repairing them but that requires special tools and skills beyond the average.

I got the pin to free up after alot of soaking and working the pin up and down useing a small allen wrench on the bottom side. This problem is solved and moving on to the next. Thanks,..

I believe this is the one that Roy posted a link too. I hear they can be had new for under $50 from a hydralic parts house that deals in Sundstrand parts. Got that info from Bunky. I just work them back and forth the way Carl stated until they free up. http://cubfaq.com/relief1.html
