if a block has a scored crank on the #2 cyl, what would need to be replaced to get it running? any machine work involved? im thinking about picking up this block really cheap to build up. thanks

 

new crank

 

what about the bearings? just reuse the old ones? or get some acl? better safe than sorry right?

 

Replace the crank and the bearings - main and rods...you will have to get the correct bearings by looking a the numbers stamped n the rods and crank. So, there is no damage to the rod that spun the bearing? No discoloration?

i always wondered how are acl bearings one size fits all? they showd a diagram or something but i couldnt understand it. thanks

 

ha. I entered this thread thinking "so what does buying methamphetamine have ot do with hondas?"

 

haha. didnt even notice that till you said it.

 

i thought your were talking about drugs, too. haha

 

hehe i think i spelled scored wrong?

 

you can take the crank to a machine shop and see if they can grind the crank. if they can you need to get thicker bearings, rod or main where ever the the crank was scored.

 

ACL bearings will work fine for your rebuild. If your crank is bad, you can have it reground and acl makes a special oversized bearing just for that

 

it depends on how bad its scored/marked
if its not bad you can have it polished off at an engine builder shop for 100-200$ but if you can feel the mark with your finger you may need to replace the crank. its best to have a professional look at it and see what they reccomend.
