Can you remove the drive on ANY of the newer Yamahas WITHOUT removing the chaincase.....or does the case have to be loosened and pulled out
 

Hey daman,
Did you see that picture of a puller that mounted on the sprocket side of the driveshaft that pulled it over enough to change the speedo side bearing? I wonder if that thing would work?

No i didnt??? yea that would be nice...



but pulling the case is my kinda way so you can clean case, gears, and chain,check bearings,etc...
 
It is definitely a good idea to clean all the parts from the chaincase and give them a good inspection while changing the drive axle bearing on the speedo drive side. Changing the chaincase oil every season is never good enough. There is a fair amount of metal particle sludge that accumulates over time in the bottom of the chaincase. I would replace the chaincase seals, fairly inexpensive and good insurance. Refill the chaincase with a synthetic gear oil or chaincase lube.

When you replace the drive axle bearing, polish the drive axle with some emery cloth and apply some anti-sieze compound to the shaft prior to putting the new bearing back. the anti-sieze compound will make the bearing easier to remove. I remove this bearing after every 800 to 100 miles, remove the seals and clean out the old grease and water. repack it with a synthetic grease and reinstall it. This regular maintenance will allow this bearing to live for many years.
