Simply flip the bearing out of the cap and read the size on the back.

@ RC

the bearings just have an audi/vw symbols and 046 701 stamped on them.

The journals look good, feel really smooth. will post pics. I don't have a micrometer...

My friend might have one...

I know we want to place the order on Friday so I am on it...

sorry,
sammy

I am meeting with someone with lots of engine building experience in a short time. He should have a micrometer.

Also, i have just re read the posts and realized that we want to place the order by NEXT friday.

Okay, my friend measured the journals just now. He did not use the special micrometer with rollers, but got a measurement of just about right on 48mm.

So it is safe to say that i can go with the standard rod bearing set.

He said that the bearings looked hardly worn, except one had a tiny scuff where some contaminant had come in through that oil hole.

I asked if he thought i should have the crank machined to polish the journals completely...

He told me that you just use an emory cloth to rough them up before installation of the new bearings...

Please put me down for one (1) set of STD rod bearings.

Prolly annoying everyone by now, but i have never done this sort of work before and I am all alone on this.

Thanks guys,
Sammy

No worries, Sammy, I'm not going to get to invoicing today anyway. I'm in the middle of buying a new car (look for a new topic on that later), so I won't be able to send invoices out until later this weekend. I'll mark you down.

You could clean up the journals with some sanding paper to get sharp edges off.
In that case, the crankshaft is already damaged (or else you didn't have to do anything

).
You just have to know what you're doing... and I only know two people who know that. My boss and a skilled collegue. After that, you'd still have to polish it. The surface needs to be as smooth as possible.
