Gearbox Magnet Placement

I am looking at the options on where to place a magnet in the gearbox to effectively gather particles, not allow them to be released by the flow of the oil, not risk damaging the gearbox and to be somewhat easy to clean.

I was thinking of ordering the magnets for the sump plate here so if they have the magnets there that is even better.

I am thinking of a stack of 2 or 3 of the 1 inch discs epoxied together and epoxied to the inside of the outer cover. Does that sound good?

I tried that idea but gave up on it.

Mine were in the frame tube and rattled like crazy due to the vibration.

No!

Better off changing the g/b oil frequently.

Did you epoxy it into place? I just had to replace the whole cluster and don't want to do it anytime soon, and neither does my wallet.

The gearbox and engine lubrication are separate.
I think most of sparkly bits in the oil are non-ferrous, so what`s the point?
The components most likely to wear are bearings or ally.
Anyway, how often are thinking of checking them?

I was thinking of checking them at the first gearbox oil change and depending on how much was collected, every second or third change.

I thought about magnetizing the drain plug but I was worried that since it is close to the gears it would just magnetize the particles and they would come off. Also, overtime I would expect it to slowly demagnetize.

Not a good idea ,I would rather take my chances of a broken gear mangling the gearbox than have a superhard magnetic lump glued in place ready to dislodge and find something to stick to.A small magnet in drain plug would be best idea just for the super fine particles that will settle to that point anyway.Change oil regularly ,go for good rides so it gets hot and drives off any condensation (do not waterblast) and there will be no problem.These are good little gearboxes and changely nice as long as you ride them on cam and not changing gear in the low end of the rpm
