Default Runout process

Wondering how all that have done so. What did you do to check it. I understand the process and am just wondering as it’s often mentioned to check it while one is in there during cam(s) swaps.

TIA

If you do it before before ordering you can then determine if gear drive or chain drive. Gear drive requires a lot less runout, 3 thousandths. When I measured mine I had a clamp on dial indicator. Disassemble cam chest with indicator on pinion shaft. Do your zero at the lowest point. Mine had just under 5 thousandths thus went with chain drive.

I know, just a query as to how “you” do it or did it.

As I alluded to, I am fully aware of how and why, but as we all know, everyone has their nuances and tricks. Learning never stops.

One way to do it attached; different ways to securely attach/mount the dial indicator. The steel plate that comes with the innner cam bearing R/R tool makes a decent base for mouting a magnetic base for the dial indicator.


Also attached is a primitive jug to mount a dial indicator. I have cut up an old cam plate to check runout but don't have a picture. Imagine cutting off the top of the cam plate; just below the bearing bosses, driling a hole centered over the brass pinion bushing for fixing a dial indicator; Google Fueling Crank Runout Tool and you will get the picture.

Thanks, but one example of what I am searching for if only to “talk about Harleys” versus other topics.

How did you rotate the shaft?

Plugs out, rear tire off the ground, in gear and just turn the back tire.
