Having trouble with search... sorry..

So I've seen some forged rods (eagles) around, and was wondering about reusing them.

I assume they would be fine to reuse, pending potential reconditioning.. I realize eagles use arp's (stretch bolts) and would have to be replaced if out of spec..

so..

what else beside reconditioning (if needed) and potential new arp's would you need?? Perhaps a stupid question, but do eagles need rod bearings?

 

i think you will be fine using them and if the bearings are bad then you will need to replace them too and what arp stretch bolt are you talking bout i dont think they should strectch!!!!!!!!!

 

All bolts are stretch bolts. That is why they hold things together. Doh!

 

Arent u supposed to see how much they stretch when u install them, not just torque them down???

Get some new ARP's...check the rods with a micrometer on the big end and small end make sure nothing is out of round or bent

 

i thought you were supposed to get arp's so that they dont stretch as much as the oem ones

 

If you contact ARP they can tell you what the bolt was length wise when new and what the service limit is. You will need a micrometer to do this as the service limit I believe is in ten's of thousandth's

 

if they didnt stretch then they could back out more easily....think about it

 

My thoughts exactly. When you torque a bolt that is what you are doing - setting it to a predetermined amount of stretch. When you disassemble it the bolt should go back to its original length. If it doesn't, it has been stretched beyond the 'yield point' and has become plastic.

 

plastic???? u must be chris angel cause i've never seen metal turn into plastic :D

 

Lol, I knew I would get a comment like that. Plastic simply means that the metal has stretched and did not return to it's original length. If you pull on both ends of a bolt (as you do when you tighten it down) it will stretch. Below a certain point, called the 'yield point', when you release the tension on it, it will return to it's original length. If you stretch it beyond the yield point it will not return to its original length when the tension is released and is said to have become 'plastic'. If you've seen a 'necked down' bolt where it is skinnier in the middle than at either end then you've seen a bolt that has become plastic. 'Plastic' is simply referring to the fact that the bolt now can be stretched without returning to its original length. The dictionary defines plastic as being something that is capable of being shaped or formed.

 

are OE bearings suitable as replacements??

 

OE bearings of the right thickness needed, yes. If this is an ls, I would recomend you use b16, acl or gsr bearings(rods retanged or course).
