Hey Guy's Im building a all motor H22. (BC rods w/ arp 2000 bolts) was putting motor together and streched 2 rod bolts so I figured Im doing something wrong. I Torqued a few rods to 95 lbs foot starting at 5 lbs going up 10 lbs till 95 lbs and its fine, but if I go by BC manual it says to Torque to 5 lbs then to 100-90 lbs with one pull, thats were I start streching the bolts (my Torque wrench dose not click when I do that) So what should I do? I just wana do this right

 

whoa 100 tq on rods? i did my arps to i believe 29

 

100lbs of torque is HUGE! Check the Helms or the ARPS website if you are using the ARPS.

100lbs on rod bolts.. what the hell..http://www.arp-bolts.com/Catalog/Cat...talog_0025.pdf

40lbs i believe for arp rod bolts.

 

You torque your rods by first figuring out the CORRECT torque specs and then using a decent torque wrench.

 

did you even bother to search? damn!
well here you go:

woah..........wtf....100ft/lbs......not even 1/2" headstuds get torqued to that spec.....

you sir ****ed up those bolts and rods....you might need new rods if the threads are no good.

 

.........damn

 

somewhere around 40ftlbs for a bolt that size.

keep this in mind
the smaller the fastener the less TQ
the larger the fastener the more TQ

so anytime you see a bolt roughly the size of something you have TQed before you know ballpark what it can take before you stretch the fastener

 

Im sure every one did a mistake before.... well got it done right today, to 45 lbs foot. let me tell you thows bolts are hecka strong, I think I messed up one thread on a rod (whent in a littel hard) but other then that Looks like it will hold up. Might need to some super glue to that one thow

 

Rod bolt stretch gauge... arp recommends using this instead of a torque spec.

 

i wouldnt use the bolts that was tq to 100lb. they are probably over stretched out

 

ummm I'm surprised they didn't break. Are you using a helms manual to put your motor together? You should check how much you stretched the bolts. Just to give you the benefit of the doubt to see that their actually f**ked up and don't want to run them. Its only going to cost you more money in the long run......
Take one of your new rod bolts and one of the used ones that your already torqued to 100 ft lbs and compare how the don't line up anymore...

 

dont expect that engine to last if you used the the same bolts they are way beyond its limit, replace them.

 

stock rod bolts specs are 23
and apr i think are 20 then 40

 

I will take apart the motor and make sure the rest of them did not get streched arp wants them at 45-50 lbs foot.

 

Where are you getting 45-5- ft.lbs from? Highest listed torque spec on the ARP site for Honda rod bolts is only 41 ft.lbs.

 

no you should replace all 8 of them regardless, its not worth the risk.

 

I agree with this. Those bolts have exceeded their elastic limit and are junk. Rod bolts are the most highly stressed bolt in the engine and deserve respect.

 

if not youll be one here in a couple days after you get it running, asking why you engine blew

 

It blew because of faulty (insert brand name here)...it's always the faulty part(s) isn't it?

 

i agree

 

never the novice builder

use the stretch guage, this article explains why.
