Torquing main and rod bolts

[danny_l_2005]

My service manual says to torque the rod bolts 14.5ft/lbs plus 90* and my mains to 18 ft/lbs plus 90* as well , is that right?

If that is what it says then it is right.

You didn't reuse the old rod bolts, did you?

I torqued my rods to 45ftlbs and mains to 50ftlbs

do what the book says. alot of vehicles call for an additional 90*

Stretch is a much more accurate way of torquing than just "click click" anyways.

That's what it say's in 7 bolt manuals, and you're suppose to use a torque angle gauge for best results otherwise just guesstimate with markings. ( white out)

For my stock rod bolts, I just took a hammer and tapped the old ones out then tapped the new ones in. I torqued them both down to 14.5 ft/lbs and plastigauged them. After that I torqued them all down to 14.5 ft/lbs and pretty much just eyeballed the 90* turn. I guess we'll see what happens when I get it back together. Not saying this is the right way, but thats how I did it with the stock 2g rod bolts.

I torqued my ARP main studs to 65 ft/lbs. Just make sure to do them in the right sequence and do them in increments with the last being the biggest jump.

Good Luck!

The torque angle method is the least accurate method to tighten the rod bolts.

Using a torque wrench is better than that if you know what the final torque should be. I personally measure rod bolt stretch. Thats the most accurate.

Rod bolt stretch is definitely the MOST accurate, followed by angle torquing, then by click click. The worse part is that a bolt stretch gauge is super expensive for a weekend wrench spinner.

40 bucks from jegs or summit will get you a good rod bolt stretch gauge.

ARP's site lists the torque angle method as the least accurate, not saying your wrong, just saying I definitely trust ARP.
