With moly, its 28ft/lbs.. anyone know what it is with 30w oil?

Thanks.

 

just go to the damn store.

 

Thanks.. that was very informative.. I sure hope it worth the 8 seconds of your life to make that post.

 

np.

quit ******* around on HT and go to the damn store.

I believe its the same(28ftlbs), but you must stretch the bolts if you use anything other than moly. Bolt stretch for these is .0048"-.0052". I'm looking for that damn spec sheet from eagle, its around here somewhere.......

 

uh, you mean to tell me the bolts don't stretch if you use moly as assembly lube? uh.... right.

 

I never said the bolts dont stretch. You ever install a set a eagle rods? The install directions from eagle tell you to torque to 28ftlbs with moly, and any other lubricant use the bolt stretch method.

 

D.. you are pissing me off.. why the f*ck are you even replying to this post????

You obviously don't have a clue whats going on and you have nothing constructive to add.

Sleeper: Thanks... The torque spec should be slightly higher when using conventional motor oil over the moly lube since they have different coefficients of friction... (ie. the head studs are 65 w/moly vs. 80 w/30w oil) Its about a 25% difference.

D: "OBVIOUSLY" the bolts stretch regardless of what oil you use you retard.. Sleeper was simply giving the bolt stretch for 30w oil.

 

I pretty sure its 35ftlbs which would be right on the 25% mark, but I need to find that spec sheet from eagle. I know its on there.

 

Hmm ya 35ft/lbs sounds about right... 33ft/lbs is for stock rod bolts...

argh.. The guy from Eagle is taking his damn time calling me back too

 

Found it:
Fasteners: Rod bolt threads and underside of head of bolt should be lubricated with ARP Moly assembly lube. Do not use oil or Loctite.

Warning: If any other lubricant is used to lubricate the bolt, bolt stretch method must be used due to the different viscosity lubricants. Improper bolt torque will cause premature failure.

It doesn't have an alternative torque value for oil, just the 28ftlbs and bolt stretch. I heard that 25% increase for oil too. Let us know what eagle tells you.

 

Hmm thanks Sleeper - I owe you one.

We don't have a stretch gauge here unfortunately... Will have to wait for Eagle to call us back.. I'll update you on the results.

Thanks again!

 

Amazing!!! A Shop full of TOOLS and no bolt stretch gauge

 

you do have a dial indicator though... i've seen it on your site. a stretch gauge can easily be fabed up to use such a device.

glad i could help you out.

alright, i felt inclined to reply just one more time... since you blatently pointed out that you are in fact a retard, i'll try and inform a few other people that might actually gain something from this post.

Bolt stretch specs are independent of what assembly lube is used. Torque is the easy way, however not the most accurate way to tighten a bolt/stud/fastner to it's appropriate strech. (because it will be dependent upon what friction the threads see) so, if you're super ****, and have the resources, slap a stretch gauge on your rod bolts when tightening them. otherwise, i suggest using the Torque and angle method (T & A gauge can be picked up 'reasonably' from snap on), followed by plain old torque wrench (using a 'decent' torque wrench - graduate your torque settings for anything over 25 ft-lbs)

so, in closing... if you havn't made it to the store yet... send me your addy... and i'll Fedex out some TSMoly to you ASAP.

Thanks for the education. Like i said, go to the damn store.
