I ordered the parts months ago decided to open it up, glad I did, when I removed the drain plug there was metal particles attached to the magnet. Once removed from the bike could feel that the input shaft was not rotating smooth, big bearing was on its way out. Once removed could see spalling on the outer raceway.
It does require a couple of tools to remove the bearings. After measuring crown gear shaft and inside diameter of big bearing decided to polish off about .0005" off the shaft, still about .001" press fit, should be more than enough for that bearing.
Bike has 135,000km (80k miles) on it.
