The ARP 2000 bolts on the Molnar rods are to be torqued to 25 ft lbs plus 55 deg. I bought a torque angle gauge from e-bay, it was cheap, like 8 bucks. To those of you that have used one, are they usually stupid, like trying to get that right angle thingy to jam on something then continue on to 55 deg without things going wonky? Is there a torque I can just torque 'em too and call it a day?
Here's what I've always done on LS engines,...many of them, I would do it as suggested on an easy to reach bolt, then use the ole cheap dial style TQ wrench to find where it starts turn again....and that's the number the rest got torqued too. Tom at Molnar has it a 55° for a reason im sure, I would call and ask him,..super nice fella btw,..and make the decision from there. I never got the reasoning behind the whole "degrees" thing, I know there is a science to it and it's done for reason etc, but if the degrees is the same then there should be a TQ Value to match it imo
If it's a six point head tighten to spec and make a mark where your next point is and turn to that mark. 12 point go 2 points. Check the torque of your bolt.
IMO a bolt stretch gauge would be way more accurate. Using a under glass dial indicator snap on torque wrench and the bolt stretch gauge I can say that not all of the bolts will stretch the same with the same amount of torque when going by the stretch number.
I agree! In my endless curiosity for why things are, I got my old beam torque wrench, and watched (as best I could) when the bolt started turning again, then looked at the torque reading.... 65/70 ft lbs VERY non precision I'll try AGAIN using the gauge, as I have 6 more to assemble/install. For other fasteners Im sure the gauge works well, but rod bolts its wonky, the rods are not at a right angle to anything to be able to jamb that allen key thing against
Yes the cheaper gauges do need a stop b4 it can read. The degrees is all about bolt stretch, molar prefers to use a blot stretch gauge, but they are not cheap and even harder to get done in there. Depending on the lube used on the threads the actual torque reading will change alot.......the angle if better than torque number for this reason to get bolt stretch. My digital torque wrench has angle in it, it's nice cause I can stop, swing back for another pull and it keeps track of all that. But it sure wasn't no sub 10 dollar part
I have no trouble with my torque-angle gauge. Not an $8 item, though. https:www.amazon.com/Lisle-28100-Torque-Angle-Meter/dp/B0002STSW6/ref=sr_1_1?ie=UTF8&qid=1533098692&sr=8-1
The "wire and clip" is what stabilizes the degree wheel so it doesn't move, causing loss of accuracy.
