ARP uses a much stronger material in manufacturing their bolts (don't stretch as much) and, therefore, don't need as much torque as the OEM bolts; they are weaker and stretch more.

However, if you have replaced the OEM pulley with an underdrive pulley, and using a crankshaft pin kit to install two pins, and using the ARP bolt (I have all three, but I haven't installed them yet), then I have been told you only need to torque it just like the old chevy pulleys and crankshaft that were keyed; 65 lb-ft. Then, the 240 lb-ft is ludicrous. But, no pins, then you must go with the massive torque.

I put 300 l on mine - and pinned the balancer. I know, it's nuts, the car is nuts anyway.

Hi pmj341,

I'm installing a new harmonic balancer next month and I intend use the ARP bolt with ARP lube.
Has your bolt ever come loose or has it held up nicely. Pleas let us know.

Regards,
Chris

Doubt you will get an answer as his last forum activity was 02/2014 11 years ago. You should start your own thread and I am certain you will get an experienced user reply.

Also, welcome to the Corvette Forum & be sure to post a PIC of your Vette.

Pretty sure the grease is for the bolt flange and washer interface to get accurate torque spec and not gall the flange/washer. Don't think you are supposed to grease the threads. I've done 2 ATIs with ARPs LS2 and LS7 this way and used ONE drop of red loctite. Neither have come loose.
