Torque of ARP bolts?

[|GF|.:Kowalski:.]

Hi gents,
can anybody tell me the torque of these three bolts to hold gear wheel to cam shaft?
I used the ARP bolts but i can´t found a specification.

Do you know the part number for those? I found this but unless your part number is in there, then you probably should contact ARP.

Hi, the link doesn´t work.

Google arp torque value chart

But i didn´t understand this chart:

 

[polish pete]

easy figure out which tensile strength the bolt your using is, then just figure out which bolt size it is.

or easier just use the factory torque spec for that piece.

 

[RGAZ]

Just torque to manufacturer specs.

You did use the lube on the threads, right?

The chart is simple. If its a 3/8" bolt and its a 180,000psi rated bolt material, then torque to 61 N-m.

If the material is a higher "grade" you can torque it more, but for the application you are showing, its not as critical as, say, the headbolts.

Personally, bolt stretch is not really needed here much, I would just torque to service manual specs.

Being cam bolts, I would clean off the lube and use Loctite....

I'll second that.

Would you consider Loctite a lube? Until it dries, naturally.
(It's just one of them questions that rattles around in my skull).

You can also just call ARP and they will give you there torque specs. I know on my ARP rod bolts I called and he said with out a stretch guage torque to 50 ft lbs. That is 5 more than stock. My main bolts went from 85 to 100 on ARPs specs.

its further down the page.

Thank you for your replies. I already torqued the three bolts with 40Nm and cleaned the threads with break / industrial cleaner. I used loctite 262 (red).

Cheers

You only want to use a small dab when using the red so I would say no, it's not considered a lube. When using lube, you want to wet all the threads that make contact and you don't want to do that with Loctite.....at least if you ever want to get the bolt back out you don't lol
