When installing the Timer, where does the little 'pin' go?

Typcially it goes like this....

The roller/brush/etc goes on first, over the end of the cam.

Then the "little pin gets inserted into a slot in the aforementioned roller/brush/etc. That slot will line up with a slot in the end of the cam.

Then a cover will slide on over the pin. This cover will hold the pin in place.

Then the nut screws onto the end of the cam.

If your car is early, the hole goes all the way through the camshaft, so make sure you don't put the roller/flapper on 180 degrees off!

Take a look at the end of your cam and see if there is a hole drilled all the way through, or if the hole only goes part way. If it only goes part way through it's easy, just slip the rotor on, insert the pin at the point of indentation on the edge of the rotor and into the hole in the cam, slide the special washer over it to hold the pin in place, install the nut and tighten it yp.

If the hole in the cam goes all the way through you have a 50% chance of it bening 180 degrees off because it can be put together two ways (the pin can go in either side of the hole). In this case you need to set the #1 cylinder at the top of its compression stroke, then you install the rotor so it's close to the contact for the #1 wire on the timer.
