New arms use a larger bearing with a 5/8 bolt threaded into arm. Very simple to replace but will last 10 times longer.

Boss left me unattended for the day. Had to watch this video to figure out what to do. Just finished changing like 14 gauge wheel bearings 😂

tWHEn we strip tilled behind a 6 row unverfurth strip-till rig...... we dualled the guage wheels on our planter.....because the strip was super soft......used 3/4 aluminum rod threaded on both ends 5/16 course........When traded the whole rig to the farmer we bought the rebale setup for a J D 459 silage special baler.....

I do know all makes and models of planter break.

You don’t have to take the threaded bushing out of the arm.
