Title: arp torque spec (rod bolts)?
Post by: turbob16hatch on April 10, 2010, 05:40:47 PM
Well i have always heard you "should" stretch your rod bolts when using arp's. but is this 100% needed? Can i just torque them to spec and not worry about the stretch?

Also i have tried to look for the torque spec for these bolts but can't find them and i lost my packaging to look up the part numbers.

Please excuse my super noob post.

thanks

Stretch is the best way as that is how fasteners work.

Which engine?

Stretch is what ARP recommends.  I was a cheap ass and didn't get the stretch gauge so I just torqued mine down to the Honda specs.

Anything i should worry about just torqueing them?

I havn't had any issues, but I am also not the smartest  O0.  I tightened mine down loosened them up and then torqued them a second time.  Everything is still holding together.

ARP shows 26 ft-lbs with their special lube.

0.005"-0.0055" stretch.

I've built a few engines with just the torque spec and no rod stretch gauge. You will be fine.

Different motor, but I torqued mine to ARP's spec of 45 ft*lbs lubed with engine oil. It worked fine so far.
