Default Maytag 72 magnet retention rivet

Has anyone successfully replaced the aluminum rivet that helps retain the magnet in the 72 flywheel? If so, are they commercially available?

Exclamation Re: Maytag 72 magnet retension rivet

The magnet is permanently installed in the flywheel. It is not meant to be removed. If it has been taken out, you probably will have to get another flywheel. BE VERY SURE to replace with one of the same type. The 72-D and 72-DA use DIFFERENT flywheels, even though they look the same. The ID and magnets are different and wont cross match. The WICO flywheel is a class of its own.

I do not know of anyone who has replacement rivets, as stated earlier, the magnet was not meant to be removed. If the magnet needs re-charging, it needs to be done in place, in the flywheel. A regular charger is used with pole pieces to make contact with the magnet poles.

Thanks Andrew for the reply.
I have an otherwise good running 72, but with what appears to be a sheared-off head of the rivet in question (see photo). I've always wondered if there was a way to replace it.

bill, your magnet should still be tight,if so just put some high strength locktite around the stud ,let it dry good and forget about it.

Unfamiliar with the setup, but how about a pop rivet? They have them in aluminum and stainless.

The aluminum rivet is installed in the flywheel assembly, then machined when the OD of the flywheel is finished (Eissmann mags). A pop rivet will catch your hand as the engine turns If it ain't broke, don't fix it! As long as the flywheel magnet does not move, you should be OK. otherwise, look for a flywheel with a close S/N, and the same model type (D or DA)

Setting a rivet is more than just peening the head. If properly set the whole stem expands to fill the drilled hole. I bet there is enough friction to hold the magnet in place even if the head is gone.
