Hi, Not much help received on this problem in UKRM or the Kawa group, so I'll rephrase it and repost.... A little research has revealed that the A4 500s alternator magnets in the flywheel of the A4 engine, had a habit of coming adrift and jamming themselves against the stator. It has just happened to me.... Several of the magnets have minced themselves up in there, but I think a replacement rotor would fix that part of the problem. The stator poles look as if they could be straightened up sufficiently and the actual coil windings look undamaged. My real concern is the fine bits of shredded ferrite material, which may have been carried through into the oil and finding a suitable replacement flywheel. Is it usual to just clean out the bits from the alternator case and fit a new (improved) flywheel, assuming I can find one? Anyone know of a source for the improved flywheel, assuming clearing the bits out is acceptable? I am still stumped on finding a way to get the D1 version of the engine to work in the A4 frame, due to the fact that the D1 has a single ignition pickup coil. The A4 has a two pickups and a completely different flywheel design, but an identical stator. The ignitors of the two models are also different. I have tried moving the two pickups over to the A4 engine, which didn't help. It simply refused to start.
