I should have taken some extra pics.
The weight has a pin, (if memory is right, its steel, pressed into the weight from the underside, could even be a bolt with no head) it goes in a hole in the front cover on the front of the gearbox. Its cast has a step on it and shims between it and the bearing in the front of the gearbox.
The pin has a hole in the bottom for a split pin so it cant lift out.
At the back of the weight on its underside, theres an arch that straddles the pto tube.
Find the slide out of a big broken vice. Cut the jaw end off or down and shape it to the arch. Or if its busted cut up some steel plate and bolt that to the front. Drill a hole in the other end and drop in a bolt. Tip it up side down, bend up some steel rod into a handle and hook it in where the screw used to go. Melt some lead up in a pot and fill the channel around the screw with lead, maybe a few holes horizontally and poke some bolts or pins in the side to act as re-bar. would be a good little afternoon project.
