Crankshaft key (Woodruff key) advanced timing PIAGGIO

Advanced crankshaft key, PIAGGIO — a segment key (half-moon) whose top edge is offset from the arc: the flywheel sits at a new angle, and the timing with it.

• The groove is offset from the middle of the arc — that is exactly what sets this key apart from a plain one; you can see it in the photo
• The part is thicker and heavier than the plain keys in this category, and its profile has two levels
• In the photo it is shown from the side — the curved bottom and the stepped profile can be seen
• Four more advanced keys sit in the same category — MINARELLI and AM6, MINARELLI and MORINI, STAGE6 MBK, and STAGE6 MINARELLI and AM6
• The maker gave neither dimensions in the name nor a drawing — only photos
• Crankshafts and the needle bearing for the gudgeon pin sit in the same category

We write only what we know. By how many degrees this key advances the ignition, the maker did not state. The product name says "spline", and in the photo it is not a spline but a segment key; those are different parts, so we are confirming the name with the maker. Before ordering, measure your old key or the shaft groove — the thickness, the height and the length — and send us a photo; we will check it before you order.
