Having a planer issue that I'm trying to diagnose.
Situation: Bought a used Rigid R4331 Planer a week or so ago, I used it very lightly to get familiar with the tool and everything worked fine. I then took what was probably too large of a pass on a test board and caused it to stall. I shut it off mid cut and then had to press the motor reset in order to fire it up again after removing the board. Ever since that reset the planer is having issues feeding. Even without the blades contacting the board the rollers will stall as soon as the board contacts the outfeed roller. I can push the board a bit and it will creep forward some but then stall again. The rollers are not slipping, they cease turning. The blades continue to spin. VIDEO OF FEED ISSUES (LOUD)
Troubleshooting: I cleaned the rollers with mineral spirits, waxed the bed & tables, changed the blades around to the sharp 2nd side. Still no luck. I popped off the covers to expose the roller chains and watched it run. The rollers had a slight 'hiccup' or very brief pause intermittently during rotation. The chains had some slack but not excessive and the sprockets looked fine. I removed the rollers and bearings, saw no signs of wear. Then I removed the gearbox and noticed that the center gear has worn it's mounting hole and brass bushings. GEARBOX PHOTOS HERE.
Questions: Is this wear the cause of my problem? Is this enough wear that I need a new gearbox assembly or can this one be salvaged? Also, when I was looking at the rollers during cleaning, it seemed like the outfeed roller was substantially lower than the infeed rolle, obviously it needs to be lower somewhat, but it seemed almost too low and since the board starts binding when it contacts that outfeed roller I am wondering if it is pinching the board too much, is this a typical issue?
Thanks in advance to anyone who reads this block of text.
