Still in the middle of this cam swap.

I didn't realize I needed .108" cam checking pins to measure the new gear (again, this is my first time doing this).

So, either I order pins and wait 'til they get here (the dealers don't carry them do they?) to measure the gears and see if they're the same...or just forget the new gear and go somewhere local to have them swap the gears out.

Any reason I should go one route or the other? Or is there another way to measure without the pins?

 

Local Indy swapped cam gears for me last spring. It cost $10. The cam, and a newly mounted tire, were ready the next day. Reckon just a cam gear swap could be done same day.

 

Living in Nashville, I'd assume there is a machinist supply sort of place that would have the pins you need. They aren't MoCo specific.

That said, unless there is obvious wear on your existing cam gear, the easiest thing to do would be to have someone swap it out.

 

If you had no problems with the old one I would use it on the new cam....

 

If you swap out the gear, you will be guaranteed of quiet operation.

If you don't, there is a possibility of having some gear whine.

Andrew's site also has information regarding color codes for sizing.

Bottom line, even if you had everything you need, swapping the gear would still be the better choice unless there is severe wear on the gear, in which case, the crank gear would be worn as well.

Are you doing this with the heads still on, or did you pull the heads?

 

A new 7/64 straight shank drill is .108 on the back end. A regular length one tapers about .0015

 

Good tip!

Perfect. That's what I needed to know, thanks! Guess I was assuming a newer gear was better in terms of longevity, etc.

I found a machine shop near me that's gonna look at it in the morning and swap gears.

Cylinder heads? Rocker covers and lifter boxes are off but the heads are still on.

 

When I had my cam installed the indie did not use my old gear, it has quieted down some now but it was a good whine to it at first.

 

If you end up swapping gears, when measuring end play it's nice to have to old gasket on the nose cone for setting it.

Not absolutely necessary but just made me feel better about clearance.
