Guidance on engine bearings?!

[Reece.]

I've got my crank, rods and pistons out at the moment.

I'm going to be replacing big ends and crank bearings. The crank bearings have D9A and D6K printed on them and the con rod bearings have D9B printed on those. Is this a size reference or a part number?

The piston rings also have N200 on the top 2 rings.

Do these numbers mean anything to anyone?

It's using 86mm wiseco pistons and eagle rods and was burning no oil so will the piston rings be ok to go again?

Lastly how do I go about getting the correct size bearings as I'm looking to get ACL race bearings and they have 2/3 different sizes.

Just a question-

Your stripping and rebuilding an engine and don't know if you should get the crank checked for correct size bearings. And if you should fit new rings or use old??????

Why are you doing this work without knowing the answers already!!!

Block is cracked and isn't usable.

All a learning curve so just need the right advise on which way to go with it.

So get the crank measured and get the bearings that are in those tolerances?

What about rings then? Do I just buy 86mm rings and get them gapped correctly?

Pistons should have come with rings??

 

[Reece.]

Basically I've wrote the car off so what ever happens to the engine doesn't matter but the rods and pistons which are forged are fine and have rings already on them and look fine also. The car had only covered 62k miles and hadn't been forged for long and didn't burn any oil.

But as said it's a learning curve and just want honest answers that will benefit me.
