I do this annually to prevent the need to replace the bearings. Did not see any pictures in the "sticky" so decided to add these below.... Need a dental tool and small/thin screwdriver to pry the seal off the bearing. Thouroughly clean the bearing with spraying WD-40 generously getting all the old grease and crap out of the bearing. Freshly pack the bearings with new bearing grease and replace the seals and re=assemble. Takes about 45 minutes to an hour to do the full job. I have seen some dirty and rusty bearings that need to be replaced, especially the driveshaft bearing. If you do this annually, you will never need to replace them.
First pics are the Jackshaft, and the second set of pics are the Driveshaft......

Do you need to loosen the track to to do this?

Nope. Just follow the instructions and pics on the first page. Easy peasy.

Shouldnt there be a seal on this bearing?

(2nd pic) This bearing is also full of gearcase lube, just clean out and regrease?

Doesn't need to be, although on other yamaha models they had a seal here just to keep the metal filings out that come off the chain and gears.

So dont bother greasing as i assume it would just mix in with gear oil?

If it's open to the chain case, it will get lots of oil
