What rod bearings are these?

[empera]

Anyone know what brand bearings are these? I've tried googling* the number on there (2F27H) with no luck. Here's a picture. Any ideas?

Thanks!

Same manufacturer that supplies OEM bearings, more than likely they are stock. Is there a number stamped with ink on either side? That indicates the bearing size, but often times the ink wears away.

Nope no number. I'm trying to figure out if these are std...before i pull out the gauges heh..

 

[empera]

did these guys make 2 diff. size bearings?

Thats a stock bearing. It should be standard

those are indeed Taiho, but they made all different sizes.. it depends on whether they're marked 'STD' or a code to equate to -/+

to quote IJ:

"Select fit bearings"

It's a standard Toyota thing, they've been doing it forever to allow for +- tolerences from their machine shop.

There is usually a chart that tells you xx Crankpin size and yy Main tunnel or Rod size will = zz Bearing Shell.

Toyota used a lot of different sizes to make each bearing fit perfect but a standard bearing usually will replaced a stock one depending on what happened to the motor.

any time there's doubt, measure and confirm the facts.. this isn't something I'd speculate on.
