YM1510D 3pt control lever broke... seeking repair advice for lesson #2

[California]

YM187 had a 'new and improved' transmission, so the shifter may/may not be the same.

On my first YM186D, I broke off the 3-point lever where it is welded to that rod. I had been grabbing the lever to steady myself when going over rough ground. Don't Do This!

But it was easy to weld the lever back on. I discovered the original welder had been a little over enthusiastic and had burned away half of the lever's thickness at that joint. If anyone else ever has to make this repair: I wrapped the shaft in a wet washcloth to avoid heating the o-ring. The rod remained cool to the touch.

Well I feel much better after talking to Hoye. I learned that this failure mode is quite common. So lesson number 2 is converted to "familiarity with common failure modes". The bad news, due to the high failure rate, is that this part has already been harvested off most "parts" tractors. Anybody with an angle on one please let me know! I may ending up cutting the broken shaft off the lever, fabricating a replacement shaft, and weld it to the lever.

...and the fix is to machine a new shaft with a collar that slides over the existing shaft and pin them together. We did move the O-ring slot significantly inward to minimize torque that may be applied across the groove via the lever arm. Today's job is to locate and drill the holes through the collar and the old shaft stub for use by the pin.
