I have a webcam and an aluminum gear I am installing. The cam gear is attached by 5 bolts. I have a one in five chance of guessing it right. What is the right way to attach the two? I currently have a case opened, crank and dizzy installed and aligned correctly. I am aware of the timing dot on the cam gear, it is the cam shaft I am not sure of.
As a backup I could split a junkyard case and pull it's cam but I am not in the mood for the labor and mess. I would much rather finish assembling my current motor.
I am following Tom Wilson's book and it only talks of stock, riveted cam gears, and to not separate the cam from the gear.
Any advice is appreciated. Thanks.

Re: Timing a cam gear to a camshaft
Only one of the five choices will place the oil pump drive slot pointed towards the timing mark on the gear...that's the one you're after.

Ah so the oil pump slot lines up with the "dot"? Perfect. It would have been my guess since everything else aligns with the case seam. It's my first build. Thank you so much Marc.

That's how the raw billets are machined, the slot becomes the primary reference point for indexing the shaft when the lobes are ground. Type Is are the same way, but they only have three bolts.

The more you know...Marc wrote:That's how the raw billets are machined, the slot becomes the primary reference point for indexing the shaft when the lobes are ground. Type Is are the same way, but they only have three bolts.
Thanks again Marc.
