Got started on splitting a 4430 yesterday. When you try to put the mechanical shuttle into forward it just grinds and makes all sorts of noises and the only way it will move is if you hold down on the lever with pretty significant force. I'll pressure wash it before I get started today.
Well I got it split and found the problem. The gear here is broken not allowing the synchro ring to engage. It looks like it had been this way for awhile.
I had the fenders, seat, and steps stripped off of it yesterday. I pressure washed it this morning and got it split and disassembled this afternoon. It took a bit longer than I had hoped, but not terrible I guess for my first time on this model machine.
