I'm trying to find a replacement crank bolt with a shorter bolt head. Ideally I'd like to find something from Honda that maybe fits another engine and was designed for this job, otherwise something with the same dimensions and grade will work. The bolt is 16x49 according to diagrams and part number ( 90017-PCX-013) but nothing lists the thread or grade and I'm away from the garage and can't check at the moment. The OEM bolt interferes with the dry sump pulley mounting otherwise I'd just order a replacement and be done with it.

I haven't been able to come up with the right search string to get an answer so apologies if this has been covered already.

Related, anyone interested in a build thread for a F20 powered 1988 M3 track car?

What's interfering? bolt head?

Yes, bolt head sticks up too far.

It's pretty long, cut off as much clearance as you need and clean up the end with a file and wire wheel. Easy.

Was trying to avoid that but I may end up going that route.

Waiting to hear back from the kit seller to see what they recommend. That or I'll return their drive kit and ATI damper and drive it using a different mounting method.

How much clearance do you need? If it were me, I'd cut it and be done with it as long as there's enough flat left to get good engagement on the socket
