Anyone seen this on rods before ?

I bought this set of on center Oliver rods online and the history is unknown. Take a look at the parting lines where the bearing locks in. I don't see how it could lock the bearing...it must be a machining flaw.

Call Tom at Molner Technologies as he worked at Oliver years ago.

Thank you Nick, I will try calling him tomorrow. Have you ever come across something like this before?

Why not call Oliver directly?

Interference fit is what locks the bearings. The grooves only locate them left to right. As long as they're round and the correct I.ID. they're fine.

Thank you, I just went to their site and looked at every rod in the catalog... the cuts stop at the parting line on all of them. Looks like they are closed for today as well.

Do they all look like that?

Earl do you think there is any way the bearing could turn and ride up the taper ?

The rest are all in factory sealed bags and look just like the one in the photo.

ive seen that before on dowel pin rods.... but never a regular rod.

Im with earl, put a bearing in the bore, crush it up and see how it fits.

Yes, I seem to remember seeing something like this on an aluminum rod with a dowel locator.

I'd contact the manufacturer.
If it was only one,I'd say someone forgot to turn around and torque the cap back on for final machining.

Not if it's round and the right I.D. it won't. Bearing's spin when they grab a crank, not because they lack a .005 square inch tang.

I don't know the sequence that a rod is built in but that is what thought may have happened.
