![]() ![]() ![]() Then I would alter the frame, not the engine or clutch. Joking aside, being in your shoes I would examine the engine mount to see if there’s been any alterations made to it in the past that would have you resorting to a less-than-optimal fix such as this. You’re going to roast that bearing prematurely, at the minimum, if you persist. To have the clutch ‘loitering’ out on the far end of the crankshaft is going to stress that side of the engine and its bearing. The clutch sprocket on the inboard side being the best is debatable, but it is paramount to have the clutch installed (in either orientation) so that it’s ‘snugged up’ on the crankshaft and as close as possible to the centerline of the engine. I recommend starting over with a clearer explanation and a proofread before posting(?). I have the ability to drill and tap the shaft to install longer set screws, but I'm not a big fan of this idea. The shaft on the Predator 212 is threaded for a bolt, but the clutch is not all the way on the crankshaft, so I could add a bolt to stop the clutch from sliding outward, but I would have to be careful about how tight I install it, and I'm not sure if the clutch would have a tendency to slide inward, which if it did at all the bolt would have nothing to push against. ![]() I know these clutches work better when the gear is on the inboard side, but without some frame modifications I'm not sure how feasible that is. My first thought was that maybe there is play in the hub causing the sprocket to pull sideways on the chain and clutch, but everything about the wheel feels perfectly tight with no play. It has two set screws that I added threadlocker to and tightened as tight as they can possibly go. The clutch slides until the chain gets misaligned and pops off. In the photo you can see what keeps happening. I'm having trouble keeping the centrifugal clutch in its place on the crankshaft of my Predator 212. ![]()
