Large crankshaft bearing. Fits clutch side for all models, except small frames.
This is also the flywheel side bearing for VNA, VNB, VBB, VBA, VLB, VLA, VBC, VNC, VB1, VS5 and VL1-VL3, so, for those, models you'll need 2.
On P-series scooters, use 133068 for the flywheel side bearing.
And, if you've already torn your engine apart, why not replace the rear hub bearing while you're in there? (Part # 90025).
