Tried searching here, internet and on Manley's website but no luck. I have Manley rods and I need to torque down the bolts, anyone know what the torque spec is? I have arp moly lube or I could use 30w oil if needed. I know they want to use the stretch method over torque spec but I'm trying to find the torque spec for now. Anyone? I can post a pic of the rods if need be.
Thanks

 

See arp as the rods come with 3/8 arp2000 bolts

 

50 ft lb

 

call the manufacturer see what they recommend on tq specs, as for the lube in the rod itself use the arp moly lube, the 30w oil has a problem with keeping the tq after multiple uses.

 

Funny thing is I used to work at Manley in the rod department and actually did most of the procedures for machining a rod including calibrating the torque wrench and torquing the ARP 2000 bolts down to spec so the big ends could be sized to spec. I think the spec was 60 something ft lbs but I forget, then again, the rods were different from the ones I have. I'll call tomorrow and research them more to double check

 

dear darla
i hate your stinkin guts
you make me vomit
your the scum between my toes
love alfalfa



60

 

Say what?

and thanks I'll be going with like 60, I looked at all the specs for all there rods and it was around 55-65

Manley's paper work say Final assembly torque, which should be 50lbs depending on what rod/rod bolts. You should just buy a rod bolt stretch gauge, summitt sells the Lunati one, its not expensive, simple to use. BUT if your not gonna do that, i'd use the assembly torque.

IMO the rod bolts are the most important part of your build, do it the correct way.
