Hey Guys,
Does somebody know the Code and manufacturer of the lower main Crank needle bearing for a 2018 GP300?(See picture)I want to rebuild the crankshaft myself and don't need the crank and main shaft contained in the set.
Thank you guys!

If you need to rebuild a crank, you'll need a new rod, bottom pin, thrust washers, and big end bearing as found in this kit.

Not sure why you'd rebuild a crank without a rod/pin change.
