I finished building a b series motor with eagle H-beams, after measuring the the clearances I found that the OEM rods marked with a 3 on the side, have the same big end bore as the eagle rods.

Does this mean that i could use the bearing codes from the block on any rod stamped with a number 3? This would save alot of time but I want to be sure that this wasn't a fluke.

 

better safe than sorry. mic everything

Eagles are supposed to be sized for Honda green bearings, which are middle of the road bearings. If your local stealership is like mine, they won't stock any bearings, so I'd suggest getting a full green set, as well as one larger and one smaller set. For $20 you can get the spares and plastigauge and know it was done right.

 

I thought the same-- the numbers matched up for green, so why not use acl's? wrong. clearances were way too tight for me. ended up using acl race bearings all around.

 

good answers, thanks guys.

I do mic everything, and will continue to do so.

 

Eagle rods are NOT sized for GREEN bearings. Eagle rods for B18s and D16s are sized as a #3 rod. The B16 rods are sized for a different code (IMSMR). You need to match up the #3 rod code with the corresponding code on the crankshaft to know what size rod bearing to start with. Do you micing from there.

true true.
lol Never understood why everyone says the rods are for green bearings .... it's like saying the journal size for the rod on the crank doesn't count when getting bearings for it.

 

Loving the responses guys, I am building another b series with Eagles, all the stock rods are #3.

So far we have ordered bearings based on exactly what is stamped on the block and crank. Its been a breeze, my only concern is that one day I'll get a rod from eagle that has different diameter big end and be seriously screwed.

Thanks, I'll let you know if I burn a rod bearing.

Oh Happy New Years, Man I'm a loser, who does this?

 

You still need to check the clearances with at the very least some Plastigauge, and even better with micrometers. There's always a possibility that Honda screwed up and measured a bearing wrong, or put it in the wrong package. The block could also be stamped wrong, or you could have read the stampings incorrectly. There's too much at stake to just trust the numbers without measuring.
