There are no bolts holding the hyd unit that I can see only two bars on each side locating it, I hit the bottom of the hyd unit with a large hammer and it moved up enough to engage the gears. It now works. i think i will have to tack weld it in place. Are the bolts holding the hyd unit on you...
I just took mine apart again and had the same problem today.It looks like the tank moved. I had it working perfect yesterday,then i put a new rod seal in it, and the problem came back. i,m getting a new handle gear monday , maybe mine is bent. Ill keep you posted.
I had the same problem with the same model 328.12001 I rotated the handle gear to a different position. and kept doing it until it worked. this might work for you?
