cub 2164 fly wheel issue

I have an 18 year old 2164 cub cadet with a 42 inch mower deck. Runs great. While mowing, a stone or something got under the hood and dropped down into the flywheel. One of the magnets on the wheel broke off. I have looked for the part# BS 807805 and all websites say that it is discontinued. I guess because it is 18 years old. I was hoping someone might know where would be a good place to start looking for this part. I would think there would be a substitute of some sort. Thanks folks

Is the magnet intact or did it smash up ?
If it is in one or two pieces it can be reglued onto the flywheel.

AFAIK all of the Command flywheels are interchangable the only difference is the size & number of the magnets.

I'm afraid it is smashed to pieces. Can one get a magnet and shape and glue it into place?

Firstly ignore my previous post as I did not read yours properly I see you have a B &S engine not a Kohler.

'Secondly post the engine numbers as requested by mark.
He has access to the dealer net and will follow up to see what it has been superceeded/replaced with

Third, if this engine has an external magneto coil & magnet thus the inside magnets are purely for supplying power you can remove the magnet dead opposite the damaged one to balance the flywheel and put it back on.
The only problem willbe a reduction of power so you might need to top up the battery now & then.

The only numbers I could find are as follows : MN. 2164...13A-264G100 Factory N. 303447 code. 98080411 type. 1147-E1 4952. I've cleaned out the spot where the broken magnet was. It just seems you could form another magnet to fit. or is that just wishful thinking? Thanks for all the help

Wishful thinking.
Magnets are either cast in shape or a powder pressing and partially fused so they don 't bend they break if cast and shatter if pressed.

Your flywheel part number is 808770, shop for best price & take your time looking as many say no longer available, but someone may have flywheel on shelf. Alternative is flywheel conversion kit part # 844818.

Wow! $300 bucks. I think a little reduced power with one magnet missing is in my price range.

I think I lost you at "wishful thinking". So to epoxy an exact copy, maybe a little thinner to avoid hitting anything, is out of the question?

You can glue in another EXACT copy to replace the missing one
Or take out the one exactly opposite

The flywheel is balanced, by weight and for electrical generation
running without 1 magnet will get up vibrations in the flywheel which may do a lot of damage.
Vibration are funny things some times a really big one that makes the mower jump sideways will have no consequences
While other times, ones you can barely feel will destroy the entire engine. :confused2:

So you remove the opposite one to keep the flywheel in weight balance.

A lot of skid steers out there run with no magnets left in the flywheel at all and they just recharge the battery overnight

So there are good good good good vibrations. I knew the 60's would do me some good some day. So if I am missing two magnets it will be balanced but I will have lost 0ne sixth the power....two out of twelve? That sounds perfectly acceptable. I found magnets on the net that are almost the same size as what I need. It would just need to be sanded with a slight concave shape. If a friend can not tell which one I replaced, I may glue it in.

Yes the annoying part is magnet making is a very specalised business and there are not many of them.
But you can not buy magnets it nevre makes sense , unless you want to sell a lot of $ 300 flywheels ( $ 700 down here ).
Good luck trying to sand them down the days of the old soft ferrite / magnetite magnets have long gone.
There is probably a business oppertunity in providing a flywheel reconditioning service.
I have about a couple of drums full sitting here that I have pinched the magnets from .
They go to an old college mate with a foundry.
Might do that this weekend as we are scheduled to get 6" so all the mowers will be staying in the shop.

Are the magnets down under of opposite poles than here...as the drains drain counterclockwise? never been closer than Indonesia. I would assume any magnet of any strength would be better than no magnet. But then again, I am only a home builder not a motor builder. This is way out of my field as you can rightly see, but I do feel confident in making an EXACT duplicate. Thanks so much for the info, it is greatly appreciated. Good luck with your endeavors this weekend.

Cubbyboy,

If you have pulled the flywheel off check around at some of your local mower/small engine repair shops, someone just might have an old used engine sitting there that is being used for parts and you might luck out and find one for a lot less the $300. The older looking places with lots of junked mowers are the best place to go parts picking.

Thanks , If replacing the magnet does not work that is exactly what I will do.

Search " Taryl fixes all- flywheel magnets".
I use a similar method but it is easier to watch than read
I use a silicone adheasive, over there use what ever he uses.
Most epoxies get too soft at flywheel temperatures and make sure you get the polarity right or you will just about reduce the output to zero.
