I am rebuilding a mini soil compactor roller.

I replaced the old 8 hp Kubota diesel engine unit with a new Dongfeng unit. I want to weld the coupling shaft, which is built from 2" pipe with rubber damper at one end, to the hydraulic motor.

How can I ensure the shaft is balanced after we weld it to the flywheel? We would like to do this cheaply if possible.

With some low friction bearings you can spin it on the shaft and wait for it to come to a rest and mark the low point, do this a few times and you may see them gathering at the bottom.

Then drill out a portion of the wheel where it is heaviest and repeat.
