OEM Yamaha Part
New Yamaha Crankshaft Woodruff Key
This is the key that mounts in the crank on the left side of the engine to guide the flywheel into the correct position.
Note. This is purely a locating guide it doesn't stop the flywheel from turning. The taper on the crank holds the flywheel in place so the flywheel nut MUST be tightened to the correct torque, 50-54 lbs/ft or the key will shear.
Standard Equipment on the following models-
XT250 & TT250 up to 1983
Brand New Stock
Also fits loads of other models, too many to list, if you have a requirement just ask.
