The Grand daughters where a lot of help. We got all of the motor parts sorted out and cleaned. Then we spent the rest of the day balancing all the internal engine parts. Pistons, piston rings, wrist pins, retaining rings (snap rings), connecting rods, and the rod bearings. Basically everything that rotates in the motors.
The crankshaft I had to send off(it is already back here). I have Minnesota Crankshaft balance any crankshafts I have done. I send them the flywheel and dampener. They spin balance them as a unit.
For a few years in the early 1990s I played around with some super stock tractors. I built a JD 4020 that would turn 5000 rpm and hold together. Then we found out my wife had cancer so I sold all of that stuff and concentrated on her health.
This engine is not going to be turned up but I always thought that the JD 4320s where supper smooth running from the factory. I want this one to be even smoother if possible.
Have also sent the transmission gears out to be lapped finished as sets. They will be very little gear noise from the transmission. The hydraulic pump is the one thing that I have not figured out how to make it smoother. They always are a little noisy.

But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
