12x1.75

 

[lenahan05]

mains are also x1.75?

 

[Schrowang]

The 12mm arp main studs are a 1.5 pitch. So i would imagine the 14mm would be the same.

Ryan, I've got a set of bottoming taps on most sizes for metric. If you're down this way you can borrow them.

All the bolts I've seen in the B-series are coarse metric (exception being flywheel/balancer bolts), so M14x2.00 is the coarse pitch. That being said, I haven't opened up my old 12v engine, so this is just more hearsay.
