Ended up hitting the bottom with my bar. It still seemed to function just fine and cut well, but the handwheel was rather difficult to move.
I took the cover off on the opposite side and turned it, and that shaft was definitely bent. You can see the crack in the picture.
Ordered a new shaft and swapped the gears over. Figured some of yal would be interested to see the guts.
Obviously you take off the two cover pieces to get the handwheel out.
There is a plunger bar that sits inside the shaft. Removing that, there is a smaller shaft with a flathead slot. Hold that and turn the toggle out. Now the handwheel which is slotted with a key slides off. The cover is held with an Allen key, loosen and it slides off too.
For the gears. The bronze color one, that is sort of concave goes on first (closest to the handwheel). The orientation is correct with the gear furthest from the handwheel. I didn't take a good picture, but on the inside 180* apart, are grooves for those balls to lock into....a clutch sort of.
The smaller shaft fits I side the larger, with a spring on it. When the plunger is engaged, it forces those balls outward...which will catch on the inside of the bronze gear and turn with it. When it's not engaged, the balls retract inside the shaft.
The smaller gear has a woodruff key in it, but it's not normal. It's simply a square shaped piece of metal it seems. Just slide the gear over the key and push it back.
Everything should come off and on by hand, I didn't need any assistance getting the gear off, but it was snug.
Not pictured was a short sleeve that fit over the entire shaft.
Anyways, just a little I learned while doing some upkeep/repairs. Put new oil in transmission. To fill that remove the motor and fill through the large Allen head. Topped off the handwheel fill port and wiped down the bar and feed. Good to go.
Just got an offset holder and new holders. Ready to go!
