Last week my planer blew a bearing on the cutterhead. It is a NuMark 12” planer, more than 30 years old. The company went out of business many years ago.
I cannot determine how to remove the cutterhead. Here’s the issue:
1. The cutterhead casting is a single unit.
2. The bearings on either end are smaller than the cutterhead circumference so the cutterhead cannot be pulled out either end.
3. From the parts schematic, the cutterhead appears to be one piece (no smaller diameter inside shaft).
I considered attempting to remove the old bearing
and press in a new bearing without removing the cutterhead, but cannot determine how to remove the old bearing. (There doesn’t appear to be any where to get a puller on it.)
Do any of you mechanically-minded LumberJocks have a solution for me?
