Crankshaft issues - Honda Prelude Forum

Ok to make the long story short I bought a 98 block and had it sleeved by GE. The block spun a bearing and the crank is scarred so I can't use it. I bought one from a guy that said he had one from a 99 Prelude. I went and measured it today at the shop and the main journal size from the 98 is 55mm. The one I bought to replace it (99 crank) measures 50mm. I read the thread by Satan_srv and it appears the main size changed from 98+ Preludes.

Does anyone have any more info on this? If you have access to different year cranks off Preludes (I know it's a long shot), could you measure the main journal and post up the sizes? Also can you check to see if there are any etchings on it (shown in pic below)?

98 Prelude crank with the etching shown.

99 Prelude crank that I bought (can't verify the year though). It has no etching on it.

Both cranks side by side. The left one is the 99 crank and the right one is the 98 crank. I sprayed a cleaner on it so the etching show up better but also makes the cranks look dirty. You can see the scarring on the right crank.

Any info would greatly be appreciated.

I can't help you with information, but I'm curious to know how you spun a bearing. Oil starvation?

He didn't do it......the block he bought had the spun bearing when he received it.
Moving to the NA forum.

my '00 had the larger mains as well.

i only have this one pic that shown the crank from when i tore it down. no markings are visible from this angle, but i don't remember seeing any either. the block was clearly marked.

I don't have my parts manual with me (it's at home), but I did check www.hondaautomotiveparts.com and it appears that the 98-00 Preludes have the same cranks. The 97 crank is the same as the 4Gen VTEC crank. It sounds like you got a 4Gen VTEC crank or a 97 crank. I can verify this with my parts manual tonight, or I bet Todd will verify it for you before I do.

Thanks guys. I am trying to return it but he swears it's a crank off a 99 Prelude. I just don't know what else I can say to the guy. Now I don't know if I should buy a new one so that a mix up like this doesn't happen again. Damn so close yet so far.

what rods are you using?

I am using Eagle rods.
