How To Clean The Magnets On A Flywheel On Outboard

06-30-2021,10:35 AM

Stator went bad so I pulled the flywheel and pulled the stator. One of the magnets stayed on the stator. Pulled it off and added it back to the 6 magnetics in the flywheel. All of the magnets take came loose. Flywheel is in very good condition and the magnets are in very practiced condition. No chips, cracks, or breaks. Can these magnets be epoxied dorsum inside the flywheel?

This has come up in the by. I don't recall how successful it was, but I practice remember a mention of the adhesive utilized. Perform a search---a browser search role performs amend than the forum search.

Also, y'all need to keep the pole orientation of the magnets right, north and s. If you accept them mixed, it volition not function correctly.

Another concern would be the balance of the flywheel. With all six being loose, the flywheel will likely be out of residuum no matter how careful you lot attempt to maintain the spacing. In turn, that'll make curt work destroying the crankshaft bearings.

Since only one magnet came off, I'k pretty sure that I put it back in the correct orientation (front to dorsum). They make a tool on amazon to identify polarity simply for a prophylactic check. It's chosen a Magnet Tester. I have a 3D Printer, so I am going to make a template that accurately spaces the magnets. I should be able to get the residual close to the manuafacturer. My research says that JB Weld is the best to use. No quick setting epoxy. Must cure for 48 hours.

Merely alternative is a used flywheel, 4010168, for $500. Ouch!!!!

Your OP post stated "All of the magnets have come loose." I suppose a 3d printer would piece of work to fabricate spacers, to position the magnet. Us jack pino savages are kind of backwards up here in the frozen tundra. I would accept used a table saw to trial and mistake cut some wood shims that fit snug betwixt the magnets that had non come loose. If it is merely one magnet that came loose, you wouldn't require the tester to identify the poles. You'll desire each end of the magnet to exist adjacent to an opposite pole, and then information technology'll strongly pull towards the next when correct. If you accept it backwards, it will repel. Of grade, you 'll have to position information technology an angle, when testing, to keep the other end from beingness impacted by its side by side finish.

Please report dorsum with your results. I don't call back anyone ever doing then.

Delight study dorsum with your results. I don't think anyone always doing and then.

I'm sorry. I should accept been more clear. The magnetics did not come up off completely. Only i came out attached to the stator. The other 5 slide together and bunched upward with the rotational direction of the stator. I did some YouTube research and have discovered they sell repair kits (replacement magnetcs and epoxy).

Here is one how to video:

I am attaching a photo of my flywheel with the magnets assembled. Excuse the uneven gaps. I have thrown it back to show direction of magnets. If you look closely, in that location is a bevel on the corner on each magnet. This bevel must face and in a clockwise direction. Same as video. I used a strong magnet. Depending what side of the test magnet (North or South), the cease earlier the gap will pull the magnet away and after gap will push the magnet. In other words, Pull-Gap-Push, Pull-Gap-Push, etc. and vice versa. Depending what Northward or Southward polarity of the test magnet you are using. A Pull-Gap-Pull or a Button-Gap-Push is Incorrect!

I will definately proceed you lot informed of the results.
