Hi there first time on this website. I wanted to know the oem bearing clearances for the rods and the main bearing clearance for my b18c1 thanks!

 

every motor has diffrent bearing clearances. Either measure with a bore gauuge and micrometer. Or use your old bearings and plasti gauge.
Any other question you feel the need to ask type it in google. This has been covered here and many other forums. Trust me you'll get your answer a lot quicker using google and your brain. .... Don't be afraid.

 

Ok I plastic gauged my new bearings and I got .003 for the mains and .0015 for the rods...will these be good to run it with those clearances or is the main clearance too lose?

 

The mains are too loose. beyond the the service limit maybe. Shoot for .002 what bearings are you using?
Did you measure with your old bearings? Or just slapped in a set and plasti gauge?

 

I got std king bearings... And I didnt use my old bearing yet...rod number 4 spun a bearing before so I don't have all the old bearings I can still do it right? I just plastic gauged it with just the new set of bearings.

 

Did you get the crank repaired??
I'm not sure on the size of king bearings but you might need to get a set of oem bearings for the loose mains.

 

The old crank was too wore down so I got another crank...oh and I just checked I have ITM main bearings std size...so u don't know what size main bearings I would need?

 

You would have to get a dial bore gauge and mic out the journals with the bearings you have now and get thicker bearings.
Oem honda bearings come in like 6 diffrent sizes there's a bearing chart on jeff evans site or laskey racing.
I can't tell you what size you'll need this is something you need to either check your self or just drop it off to a machine shop and give them your bearings and tell them the clearnces you want and they should be able to make it happen or get the appropriate bearings for you.
For a decent dial bore gauge and micrometer set its going to run you from 250 to 300 dollars and that's if you find good deals or used parts.
If you don't have machine tools just go to a machine shop they shouldn't charge much just to measure your journals and tell you what bearings you'll need.

Take a look at the oem bearing chart.
Find info on the size bearings you have now and go from there.

 

Ok sounds good thanks a lot! I was kinda lost before now I'm on the right track.

 

Hey I re torqued down the caps twice and plastic gauged then I got for main cap 1 .0015 main cap 2,3,4 .002! That not good to run cuz of cap 1 is .0015 right?
