ZZ4 water pump pulley bolt size
What size are the water pump pulley bolts for a ZZ4? I need the size and thread pitch only. I've spent an hour and half a dozen freaken combinations without success.

I tried 8mm x 1.25 and it seemed way tight. 5/16" was about the same. 7mm too small. ?????

Try 5/16" x 28 I think it is SAE thread.
Vince On second thought, I remember having a hard time trying to find bolts to fit my Fastburn crate WP. I eventually retapped the existing holes to accept 5/18x28 and used grade 8 bolts. Vince

Thanks for all your help guys. I will need to retap mine now anyway. I wasn't able to get the 8mm x 1.25 tightened and on removal broke one off
