Replace pilot bearing
I’ve done some investigating and am pretty certain my vibration is the pilot bearing. The flanges are perfectly parallel, and when I pry on the output flange I see a bit of movement of the gear assembly.
Also when I was winterizing on the hard I ran it in gear up to 3000 rpm, and though with no load the vibration was hard to detect, it did suddenly make the distinctive noise of a worn-bearing harmonic I have heard many times in failing power tools.
It looks like I have to pull the rear bearing holder and flange as well as the whole reversing gear housing. Any tips?
