Crankshaft bearing, connecting rod for BETA 4 stroke
Crankshaft bearings for BETA 4-strokes.
When to replace them?
They carry the crankshaft in the crankcase. A worn bearing develops play, noise and vibration, and eventually damages the case or the crank. Replace them as a pair with the oil seals during a bottom-end rebuild, with the same size and internal clearance as the original.
Brands available: NTN, PROX, WOSSNER and HOT RODS.
