BLT Posted April 13, 2007 Share Posted April 13, 2007 Has anyone ever attempted to glue one back in place and if it was a success, what was the adhesive used. I have a magneto that needs some help. One magnet loosened up and needs to be glued done again or I need to find a junker 5 or 6 HP snowblower TEC engine. ***Fixed*** I made reference scribe marks on mag where old magnet was for location later. put paint mark on magnet for orientation. Used gasket scraper to clean out old glue marks, buffed off magnet lightly with wire wheel. Then I mixed up a batch of NAPA - Permatex quick dry epoxy, coated the magnet located it and held all together with a "C" clamp. After two hours, curiosity got the best of me, the magnet felt solid in place reassembled engine and Wha -La back in business again. Also keep in mind that this only works where ceramic magnets are use and they were glued in. A lot of mags are not that way, especially Briggs.

shanhamm Posted April 13, 2007 Share Posted April 13, 2007 I heard (have not tried myself) that a good epoxy would work fine. lightly scuff each surface with 80 grit sandpaper, clean with laquer thinner or acetone. From what I heard it works well. Link to comment Share on other sites More sharing options...
Ronald Hribar Posted April 13, 2007 Share Posted April 13, 2007 I know someone did it, and they also said that it has to be replaced in original position in regards to polairity. I think Al had input on the post also. Link to comment Share on other sites More sharing options...
mendon-chalmers Posted April 13, 2007 Share Posted April 13, 2007 I had it done to 3 magnets on 1 kt19 asked my local NAPA dealer, they heard of it but not around here so they used me as a ginny pig the epoxy I believe came from locktite around $50.00 for the stuff they payed for & kept the stuff & glued it on for free. that was 2 years ago & still going. yes they do have to be put back right or you'll only get 12 volts if you test the other magnets on it I think it goes north end of one buts up to the south end of the next. if you can get your hands on a 40-50 year old manual they show it great.I had to show the NAPA guy because not working with it every day he didnt think of it.

A lot of mags are not that way, especially Briggs. Another thing to keep in mind is that this should be attempted ONLY with magnets that are inside the flywheel. There, centrifigal force helps to keep them in place. External magnets, on the outside of the flywheel can become shrapnel if they let loose.
