My guess is that you have the correct pin bushings. Sometimes you have to file a slight chamfer on one side of the rod to to be able to get the bushings started without scoring the back side ot the bushing. Light polishing of the bore also helps.

Once installed .010 to.020 undersize bore for the pin is about right. Since they are crushed this much it is not unusual for the ID to be wavy after installation. Good practice is to burnish the bushings. This expands the ID some and insures that the OD is making good contact with the rod. It also helps prevent the bushings from coming loose. They can then be brought back to the proper size with a good sharp reamer but since the proper clearence is .0002 (two ten-thousands), it is next to impossible to do a good job with a reamer.

The best tool for the job is a wet bushing grinder. The pin bushings are sized correctly when light thumb pressure is needed to push the pin through the rods when oiled with 30 weight oil.
