Rod bearings on my 300

If I put the wrong set on a different bearing jornal. Will this be a big problem?
What about shining them up with some emery cloth?
Bad idea?
Putting in a used set of sleeves and pistons in this thing. Trying to finally get her running.

On another note, I wouldnt use any emery on those bearings, if any grit gets onto that bearing material your gonna spin a bearing. Just my thoughts. Good luck.

You will need a micrometer or a veneer caliper to measure each journal. You must mike each journal in several places, I usully go for 4 places, left and right side then again at 180 degrees.

Try the plastigage bit first. All you need is a torque wrench. You put a line of plastigage on the journal along the length of the journal, install the cap, torque. Remove the cap. The paper containing the plastigage has indicators along the side. You compare the indicators with the crushed plastigage to determine the fit/clearence.

Check the back side of the inserts for parts numbers.

Actually, It's only that two great minds run in the same circles. I read the query and typed up an answer. When I posted I discovered that you had said pretty much the same thing. There is only a few minutes difference in our response. Oh well, If I can't be first, second will do.

As far as the polishing, you might be able to use some really fine Scotch-Brite, but I would be careful with even that.

Just make sure the inserts are clean, no damage. I wouldn't suggest polishing them.

Plastigage is available at auto/tractor parts stores. Get a stick of .001 to .003 inch - not expensive. $3 - $4, don't remember. One stick should be all you need.
