If I had to guess, I’d say the shaft broke, not the welds. It happened to mine also. I’ve got the Peerless 2300 in mine and I think you’ve got the 820? The Bull gear and carriers in both of them are basically identical. I welded the shaft to the gears, and I welded in between the teeth of the axle gears, so that if it broke, the gears could not mesh and it would still be “locked”. After it broke, I thought the welds broke but after investigating it I found the pinion gear shaft itself is what sheared in half. I put it back together with another shaft from another transmission. This time I did not weld the gears to it. I just left it with the welds in between the teeth of the spider gears. It’s not locked up tight like a solid axle or anything but it seems to be holding fine and both wheels will still turn at the same time. It’s actually a little more forgiving because the wheels can move slightly independently of each other and it seems to help just pushing it around in the shop. Anyway, I did a video on how I initially welded it and another one where I opened it up after it broke. The whole thing started by watching Redzz02 video on how to weld/ lock a 2300 series transmission which is linked in the description of the first video. You might just go with a solid go cart axle and doc locker at this point though, plenty of videos on that out there too

Thanks Jason, I will check it out. Looks like content for another video!
