I usually check the fit from the outside holding the long side and putting the shaft down in the hole and rotate it to make sure it is not over size. Then oil the hole in the frame and I usually take a small tip of a toothpick on the right side in the groove, this will lift the long side slightly up and the peg/shaft will go into the hole better. Use a small pin punch and light ball peen and lightly tap it into the hole and remove the toothpick to the right and check the fit with a couple of light taps of the punch. DONT force it or it might break. Then as you install the bolt you should feel resistance on the right side as the round part of the bolt is lifted slighty above the larger hole in the frame. This is indicating that the spring is doing its job and pushing up on the bottom of the bolt. Push down on the bot as you push right on the flat side to get it in place VOILA......or something like that. DONT USE a HUGE THOR HAMMER!!
