Thanks to Steve Shore, I now have a replacement ring to put on my wide deck motor whose mounting ring split into many pieces due to rust. I plan on using an angle grinder with a cutting wheel to trim off the remaining pieces of the old one, and then welding
the new one on. But, I'm wondering if there could be problems from heat or vibration (from the grinder), potentially damaging the permanent magnets inside. I haven't opened the motor up yet, but my understanding is that they are glued in some way to the inside
of the motor shell - which could put them pretty close to the grinding and welding. Any potential problems there?
Would it be better to instead attach the mounting ring upside down below the remnants of the original one, and attach it to the underside of the mower deck?
THanks, Mike
