The NOS Bluepoint/Snapon kingpin bushing reamer showed up today. Big Thank You! to Jerry for giving me a heads up on this being available. You can see the part number, PN 922 in image 1 below. RR 922 is the actual reaming diameter of .922 which is perfect for the stock bushings and kingpin that is .921 diameter. The other images show how the RR 922 reams both bushings in parallel. The bottom pilot cutters start and center the process and the uppers complete the job. The tool diameter as shown in image 3 keeps the reamer centered as it passes through the bottom bushing.
This is my first attempt at kingpins and it's a fairly easy job with proper tools. I temporarily installed one spindle and the kingpin slides through the bushings and axel with slight finger pressure, zero binding through the full range of rotation. Clearance is .001.
I can't imagine anything better than the Snapon tool for this job, unless it's a healthy checkbook. Two local shops were upwards from $300. It's about an hour job once things are clean and bushings are ready to install and the reamer is in hand.
