QWKDTSN Posted April 8, 2002 Share Posted April 8, 2002 I'm curious what size bolts to get to secure my crank pulley to the harmonic damper. I tried regular 3/8" header bolts just to check the thread and it didn't seem right. The thread isn't anything I have any spares for. Could it be 3/8" fine thread? Thanks.

Guest Anonymous Posted April 8, 2002 Share Posted April 8, 2002 Yeah its a fine thread. When I did mine I was already to go, slap on the pulley WTF.... Its either 3/8 or 5/16 NFT, sneaky make the whole motor course until you get to the pulleys.... I guess you need alot of threads to hold that whole mess on there with the spinning belts and all.

QWKDTSN Posted April 8, 2002 Author Share Posted April 8, 2002 Thanks a lot. I'll run down and pick up some 3/8" fine thread, if they're wrong i'll return em and get some 5/16"... PS.. here's a picture of my setup. I'm so glad I ditched the short water pump. Quote Link to comment Share on other sites More sharing options...
