I’m not sure David, easy enough to figure out. Grind with an angle grinder slightly. Just enough to see the spark pattern. Iron will be red and steel orange. :thumbsup:

In my little experience, building up the area with weld has not worked up so well because of gaps. He who has MIG can most likely do it, bu the who has not, not so easy. Watching with interest.

My original thoughts on building up the worn area with weld was the possible interference with milling alignment and boring tools. Taking into account the ideas received here makes me thing welding is worth trying. Once the transaxle can be mounted to the mill angle plate, any weld restricting the alignment shaft insertion can be . Then the alignment tool can be reinserted. The centre line found and proper boring can be accomplished. This will allow for Oem seal and bushing to be used again. :weld1:
