Balance gears
Westofb,
I can give you my observation about Balance Gears in the K321. I also have a 149 I am rebuilding an engine.
Mine knocked bad, I pulled it out and tore it down. It was difficult to get the flywheel off and difficult to get the bearing behind the PTO off. After taking the bottom oil pan off, the engine had been rebuilt at some time, a chunk was broken out of the bottom of the cylinder sleeve and the rod had hit the case and cracked it big time.
Now back to the balance gears. They were both loose on the shafts, wobbled and didn't line up with the other gears. After I finally got the crank out and the balance gears out, each of them had some of the needle bearings gone. I have no idea how they hadn't torn up something else as loose as they were.
Turns out my block is junk, so we are putting a new block in it (not new but a used one) having it bored out and the crank turned, and the balance gears will go in the trash.
Just my .02 cents worth. They are hard to get out, the crank must come out to let one of them out and off the shaft.
