I have decided to overhaul my engine completely, which was running fantastic. When I dismounted the crankshaft and main bearing, I didn't see if its std or oversize because it only said some numbers and letters. I have taken a picture to help with the problem. The order from the picture from left to right: #1 rod, #5 main, #4 main, #3 main, #2 main and #1 main. Is it ok to just put some std main and rods bearings? Thanksss..

if it was running fantastic, why overhaul it?

Service manual has the test procedure and spec for the crankshaft journals. That should answer all your questions.

link to the fsm in my sig, might have to click around to find it.

a $20 dial caliper would probably come in handy.. harbor freight sells them...

Just wanted to overhaul it because engine is out and it had 260k miles on it. Want to make sure it last me some good years.

I have read the service manual and my question is that the aftermarket bearings arent like the toyota stock ones that each one have a specific number. The aftermarket bearing are std or oversize, is it ok to put the std aftermarket?
