My Bobcat 642 uses a Hoof governor mdl BD 856 A. I'm in the process of replacing seals and bearings. Here is what I have so far that may be of help to others undergoing a similar endeavor. Bearing: Timken MM202K. Pulley: Grainger PN# 3X909m (will need to drill to 15mm ~ 19/32"). Still searching for seals and bushings. Here is what I have on them so far: Front seal: OD: 28.5mm. Shaft size: 15mm. Width: 8mm. Not yet sure how to handle the actuator seal. If anyone is out there who has experience rebuilding these governors I welcome input.
