Reconditioned Rods - is this one ok?

Just got back a set of DOOE Rods from my machine shop for my 429 build.

Please look at the photos and tell me if this one rod is ok?

The main journal balance pad is completely ground off - obviously to balance it.

Do I need to get another rod?

Balance pad ground all way off.  Is it ok to run it this way?

Thanks

Can our moderator fix the photo link?

Thanx

Nice Bike Builds. I would weigh the big and small ends of your rods and see how that one compares. I think the big end will come up light but, until you check you can't be sure.

Edit: Check Your Total Weight and Compare.

I have used makeshift jigs and digital postal type scales to get an idea how close the rods are.

I don't see how that one could balance with the others. It also looks weak to me. I know that's just an eyeball opinion, but I'd sleep better having spent a few bucks for a replacement.

^^^^^^ Same here, someone mixed the set or something else is off, as cheap and common as the DOOE and truck rods are I would swap it too.

Checked and compared 2 sets of piston/rod sets came out the same weight.

Will be getting another rod and getting it replaced. Above rod must be a fluke.

So can the machine shop remove and use the same ARP bolt in the new rod?

Rods with smaller balance pads are generally though to be stronger than ones with large pads because for a given amount of rod end mass more of it is in the rod itself instead of the balance pad which contributes nothing to strength.
