Crankshaft key (Woodruff key) advanced timing STAGE6 MBK

Advanced-timing crankshaft key STAGE6, for MBK engines – a segmented key (half-moon), whose upper edge is shifted from the arc's centre. Because of this the flywheel sits at a different angle, and with it the ignition timing shifts too — that's what the supplier means by calling it "advanced".

• The groove is shifted from the arc's centre – this is exactly what sets this key apart from a plain one; you can see it in the photo
• The part is thicker and more massive than the plain keys in this category, a two-tier profile
• A narrower edge at the top, running onto the half-moon across the rim – the same profile as the second STAGE6 key
• The same category has a second STAGE6 advanced-timing key – its name names MINARELLI and AM6 engines
• Neither dimensions in the name nor a drawing did the manufacturer give – only photos
• You will find crankshafts and the needle gudgeon-pin bearing in the same category

We write only what we know. By how many degrees this key advances the ignition, the manufacturer did not state. The supplier calls this part a cotter pin, but the photo does not show a cotter pin — it shows a Woodruff key (a segmented half-moon key); these are different parts, so we are checking the name with the manufacturer. Before ordering, measure your old key or the shaft groove — thickness, height and length — and send us a photo; we will check it before you order.
