Final drve drain bolt

I had a leaking seal so I split mine had the tools made the compatible bearing in question was from a cbr 1000 crankshaft if I remember rightly

I think the hardest part to pulling the final drive apart is removing the splined coupling from the pinion, then removing the pinion from the carrier.

Since this isn't required, simply remove the crown gear housing, pull the magnet then bolt it back together. Looks like it uses an O ring as a seal. No need to fuss with the pinion bearings, shims, etc etc etc.
 
Don't forget to remove the remainder of the broken drain bolt it will be a whole lot easier with it apart .
 
I've often thought if this happened to me where I had to remove the coupling, I'd use a cutoff wheel on a die grinder to relieve the compression on shaft. Then when completed I'd run a weld bead down cut area after coupling back in place. May work, might not, but at that point what do you have to lose.

You cannot take the final drive apart. As far as getting into where the magnet fell, it is a sealed unit.

You could get the magnet out with another magnet but the other pieces I imagine are steel you can try to get as much with the magnet and use some motor flush liquid and pump it through to get all the pieces and blow with air and install a new magnetic plug and use an easy out to take the rest of the plug out that didn't come out and is still in the plug hole and be careful not to bugger up the threads or you may have to helicoil new threads into the casing, good luck, those final drives are expensive, that's an expensive oil change and a tough lesson too, don't force anything with aluminum
