Assembly torques ARP and Crower.

Hi.

I'm wondering if anyone knows the assembly torques for Crower rodbolts (for Crower con-rods) and ARP mainstuds and headstuds.

Seeing you are new here I'll break the ice and go easy on ya. Welcome to Supra Mania :icon_surp That was my sentimental moment ha now for your questions. First thing people will say is use the search, and I will too, it helps a lot. Also try checking out the Cygnus page, a.k.a. the Supra bible. IIRC ARP rodbolts are 55ft.lbs, not sure on Crower (someone correct me), ARP head studs: by ARP they say 75ft/lbs with their moly lube, members here will say between there and ~82ft/lbs. Main studs on ARP's site say 75ft/lbs. Make a profile so we can all see what you have done or are planning to do and make a thread in the introductions area if you haven't already!

I agree, use the specs called for by each of those suppliers.

ARP and Crower should have that provided with their parts.

My ARP head studs are at 103lbs with moly lube. (Too high say some.)

My ARP main studs are at what ARP suggested..I don't remember actually..

My Pauter rod bolts are at what Pauter reccomended, 75lbs I think.. but I'm not sure.. it might have been 55lbs.. I don't have the paperwork here at this time. (It is somewhere, but I don't know anymore.... LOL)
