On the front of the cam where the timing gear and fuel pump eccentric go there is a pin that inserts thru these and into the cam. Is it normal for this pin to be able to go into the cam so deap that it does not enguage with the eccentric anymore? Should I just push the pin in untill it is flush and then put in the bolt? What holds in the pin or keeps it from slipping in further when the motor is running? Should the pin be longer? It is a comp cam camshaft.

Thank you
Jim

Normally Comp supplies both the 2 pins with their kits. One is longer than the other. It sounds like the one you have is the short one and you need the long one to engage with the eccentric.

You really need to get the right pin. What ever you do, don't just partially put it into the camshaft. The correct pin will press fully into the cam and still reach the eccentric. The washer under the eccentric bolt helps keep it all together.

How much too short is the pin that you are using?

One quick fix is to insert a ball bearing into the cam behind the pin. Drive the pin in after it, that will put it out far enough to let the pin engage the eccentric. Or just use a later 2 pc. eccentric, the center stamping has an ear folded in to engage the hole in the cam gear.
