Instead of putting the shaft in place and then closing the case, which didn't help the pump issue, I assembled the pump and and new yoke housing and set the yoke, housing, oil pump and both shafts into the other half of the case together. It seems like putting the pump and shaft together with the new yoke housing, the shaft fit into the notches and the new yoke bolt held it in place?
Otherwise, there's no good way to do it? If I close the case and put the housing and yoke on, when I go to tighten the yoke nut, it doesn't necessarily pull the shaft straight up into the oil pump grooves/teeth. I'm afraid if they don't slide together right and I keep tightening the nut (which isn't in the hole but off center) it will only bent my oil pump?
So I pulled both shafts and chain out, fit the rear shaft into the new sye housing and installed the yoke and nut. It looks and feels like the shaft is now into the oil pump but you can't actually see it to say for sure but it feels right to me. Now I'm putting the entire case half with new housing and yoke and both shafts with chain back into the other half. I am assuming if I ever remove that yoke nut, the shaft will fall further inside the case and out of the oil pump?
Does all this make sense to you experienced folks? And do you think I'm safe to move forward?
