Keyless Chuck Repair

[f350ca]

Took some time and tore the chuck apart. Was dry, especially where the bearings are. Cleaned it up and lubed it with CV joint grease. Its better but still not silky smooth. My try some lapping compound on some of the mating surfaces.
Saw the little pin between the threads and the part the jaws run in. It wouldn't drive through so I drilled it out only to find it was just there to register the parts when they slide together. DUH
