I have a custom gearbox similar to the one agk sells for the Predator engines. This one is different from theirs in the fact that it originally had a square piece welded on to one end so that the shaft could be slid through and have bearings at both ends of the shaft. I hope that I am making sense here. The reason for the shaft being installed this way was so that the jackshaft output sprocket could be slid back and forth along the shaft to allow adjustment of chain alignment without having to move the engine. Recently, I noticed that the welds on the back were cracking. I attempted a repair which did not work. I then decided to cut off the part that was welded on and cut the shaft down so that it would function exactly the same as agk's jackshaft. The problem I am having now is that the shaft will not stay in place, even though I am using two sets of bearings and bearing hangers to hold the shaft in place, its moving around and therefore my chains will not stay on. Is there anyone who can tell me how to put it back together so that I dont have to buy a whole new gearbox? Or am I screwed?
