Rebuilding an H Series block!! Where to buy oversized bearings??
Hey guys, I am weighing my options here. I have an H23 block that has a spun bearing. With the crank in...I can push one of the bearings out pretty easily. The others three are too tight to push out.
I met a guy at my work who said that he would take a look at it and see if he can fix it pretty easily. He works mostly on muscle cars but he offered to help me fix up a motor since I mainly race my car. He said that he will do the work for free.
He advised me to pick up a high mileage H22 swap and he would rebuild the whole thing for me for $400-$500. I figure since I already have a block...I might as well see if I can use it and get the remaining parts from a local seller.
My question is...where can I get these oversized bearing from?? I want to have as many questions answered before I take him all my parts to put the engine together.
Is there anyone here who has rebuilt their H22/H23 block after spinning a bearing??
I am not going to do anything rediculous with this motor. I just want to build a solid H motor using as many OEM parts as possible. I will swap this motor into the car when my H23 dies...though...after a track event on Oct 12th and 13th...I fear that might be sooner than later.
OT question: How do I make the block look like new again?? Wire brush??
Thanks, sorry for the long post.

i am in the smae perdicament (sp?) as you, i bought a block that i thought was good and it has a spun main. I am taking it to a machine shop, and i was going to start looking into places where i needed to find oversized bearings. my other option was to bore the mains to 55 mm and us a 98+ crank and bearings. but i would rather stick witht he 50mm mains and just bore alittle and find oversized bearings.
im doing the smae thing you are. any pics of the mains ?

Can you provide us with some more info on what you had to do to the block to make the OEM crank work properly?? How much did yuo have to bore it out?? How much did the whole prcess cost?? Any additional info is appreciated.
Thanks

If the crank is salvagable (not cracked or has too much material removed from the journals), then you should have the crank re-ground, and the appropriate after market bearings will need to be used (ie. .010 under, .020 under etc according to how much material was needed to grind away). You will need to have the crank magnafluxed to first check for cracking, and then have the journals mic'd to check the journal sizes. Usually having a crank re-ground costs around $150 plus the new bearings. Cleavite, Top Line, ACL all make under sized bearings for most Hondas. Also, if the main journals in the block are thrashed, the only thing you can do is have them align-bored/honed, that is if they are not too far gone. This involves cutting the caps down, so you will need new dowel pins for the main caps. That can run anywhere from $150-$250 and takes special equipment that even most automotive machine shops don't have. Hope this helps.
in my case my crank is fine, and i only hae one mildly spun main, what i have is a h23 block thati am swaping over all my h22 stuff to. so what would be the couse of action , have the journals bored over and just use bigger bearing to fill in for the metal removed?

My engine builder sent out the crank, took of .010 and he put in the Clevite oversized bearings. Nothing had to be done to the block to make this work. Not sure of the exact cost for that alone, because it was included in the $750 he charged me for the total rebuild, not including parts.

If you are certain your crank is OK, you will probably have to have the Mains Align-Honed. You need to take what you have to a machine shop or a good repair shop to look at what you have. I'm still not sure what you are trying to do with the two setups.
