Is this rod usable? pic
 

Well a fwe months ago I bought some used eagle rods. They were barely used and looked fine when I looked at them, but i took them out of the box again yesterday and noticed discoloration on one. Maybe overheated or spun a bearing? What do you guys think? I'm probably gonna bring it somewhere and have them check it out.

of all places to take a pic, you put the rods between your legs. nice.

i wouldnt worry about it. just me.

Re: Is this rod usable? pic
 

I take it that rod took some spun rod action? i would check all the clearances and dimensions with a set of calipers and see if there is any damage

Re: Is this rod usable? pic
 

For peace of mind maybe you can contact Eagle for an individual rod, cap, or both. I dont think there is any way of testing its strength, but Im sure inspection will determine its trueness.

Re: Is this rod usable? pic
 

I wouldn't worrie about them being weak but I would take them and get the bore checked. Just to make sure there still round/ right size.

Any pics of the inside? Any notching from the seat on the bearing?


















































Any pics of the other side? Any notching from the seat on the beering

Re: Is this rod usable? pic
 

your fine but do make sure they still accept your bearing size .... i.e. stock .010 over or whatever your running

Re: Is this rod usable? pic
 

plastiguage in several spots
what are those horizontal scratches

Re: Is this rod usable? pic
 

sometimes the cap get stuck, maybe the guy heated it up to get it off. i know that waht you have to do to get a stock piston off a stock rod.

Re: Is this rod usable? pic
 

That rod is junk.

Ben at importparts will sell them individually. You might try TT, they offer really good service along those lines, too.

i think joseph is right.. look pretty smoked to me

Discoloration from heat = warpage + ruined temper.

Sounds just like a CC-Fab manifold!

Re: Is this rod usable? pic
 

they get more discolored then that when you use a rod warmer to install press fit piston pin in the small end ??? I know what you are saying but I dont think it has been nearly hot enough to damage it, but it would be bad if I was wrong and she came apart again :-X

Re: Is this rod usable? pic
 

looks like it spun a bearing and they tried to sand it down :-X

Re: Is this rod usable? pic
 

jUst have your machinist look at it.

Re: Is this rod usable? pic
 

I'd plastigauge it a few times on the journal you plan on using it, then take it to a machinest to make sure its cool, I'm sure its fine.

Re: Is this rod usable? pic
 

The rod is supposed to be taken to 400 deg, pin chilled, pressed quickly together. That's not enough temp to discolor or damage the metal.

Old redneck machine shop locally was heating rods with a torch to fit pistons, discolored on the middle + small ends, had a couple of them fold from fatigue because of that.

Re: Is this rod usable? pic
 

its toast, i had a friend that bought a set on ebay and they were the same way.then the machine shop measured them up and the rod bore looked like a damn egg, they said just buy a new rod.

Re: Is this rod usable? pic
 

I wouldent use it unless a machine shop measured it out and ok'ed it. no use in building a motor and driving on it for 100 miles before you spin a bearing.

Re: Is this rod usable? pic
 

yeah Pete, i would just get them checked out.. ya never know

Re: Is this rod usable? pic
 

get the checkd out it looks like someone got it micro plished

Re: Is this rod usable? pic
 

i thought you might like to know... i just dropped my pan and pulled the rod that was wiggling around. The cap looks the same exact way. Alll discolered like that. My bearing looks like ass. Its paper thin and material was pushing out the side. its fucked. join the club :-[

Re: Is this rod usable? pic
 

when in doubt throw it out

Re: Is this rod usable? pic
 

how about instead of everyone tellin him to take it and check it tell him how to check it with a caliper or bore scope
a bore scope is really un needed though put th erod together with bearing in rod open the caliper perferably a dial type and measure about avery 1/4 on an inch around or even .10 and then get stock tolerances from eagle compare you should be good the sanding problem is easily resolved with a thicker bearing you shouldnt have a problem with it being egg shaped if you do get a new rod or vise it while using a caliper should work out for you

Re: Is this rod usable? pic
 

Check it with a borescope? bore scopes are for sticking down a sparkplug hole to check a cylender without taking the head off. A caplier and sand paper isint going to do the trick either... Yeah lets juts use sand paper and guess within a 10th of a millimeter of what the bearing were going to use on a rotating assembly ::) youd be supprised how easy it is to ---- up on a very very little thing you couldent check with that caliper and end up spinning your bearings. And when you have allot of money and wrench time into a fresh built bottom end you dont want to chance it on some bullshit like that.

Re: Is this rod usable? pic
 

I think dial bore guage is the term we are looking for ladies and gents. I agree with rawr. Dial calipers are good for measuring within about 0.001" usually. considering bearing crush tolerence is usually specified in .0001" then a dial caliper isn't going to cut it. Most of us don't have a dial bore guage because they start somewhere around $400 and go up from there. So like everyone has said, a machine shop would be best to check out the journal for out of round proper diameter. I do have to agree with JD, I wouldn't trust a rod that was discolored that badly.

Re: Is this rod usable? pic
 

first off ---- face im a machinest so with that said i said nothing about using sand paper it was said that that was already used on the rod most people that sand a machined surface like that arent that stupid as to use lanything below a 400 grit paper which would be fine for this and the tolerance i mean ---- i wetsand most of my machined surfaces before sealing anything and a machine shop odds are is gonna tell you to get a new rod they dont wanna deal with it.

and thank your for the corection on the bore guage

Re: Is this rod usable? pic
 

Just go by a machine shop and get it checked.My year one machinist instructor would kick you in the nuts for measuring that with a caliper. :1

Re: Is this rod usable? pic
 

well your machingin instructor can lick my nuts too

Re: Is this rod usable? pic
 

Haha. Good stuff.

Re: Is this rod usable? pic
 

maybe he would take it to the shop because he hasnt used one before and doesnt trust his judgement.

Re: Is this rod usable? pic
 

please disclose the name of your machine shop we can all stand clear lol wtf are you saying? spell check is your friend

Re: Is this rod usable? pic
 

the dont do auto motive machiniing and just becuase i can spelling is unimportant its a ------- forum
and for the measuring and truing of this peice ive suggested bore guage and caliper if your stupid enough to have to second guess yourself you shouldnt be building the engine anyway

Re: Is this rod usable? pic
 

ATTENTION PLS KTHX!!!!

I've had an entry level metallurgy class. Plus, I have spoken to Brad Z of RLZ about just this thing... we went through it with Speed Phreak's 2.0 LS.

The temperatures you take steel to in order to temper it does not discolor it, or warp it.

The temperatures it takes to discolor steel ruins the temper, and warps it.

Throw the goddamn thing away, you bunch of ------- douches.

Re: Is this rod usable? pic
 

check up one more "im smart i took a class " jackass for the count

Re: Is this rod usable? pic
 

Nine years worth of classes, to be exact, and I'm at least ten times smarter than you are - no offense.

Plus, I mentioned Brad Z.... three Pro-Stock wins, three Winston Cup wins, and eight NHRA world records don't lie. I know where to go with my annoying little Q's when I can't logic it out with my own noggin.

Re: Is this rod usable? pic
 

You win.

I agree, I think you should ditch the rod, or take it to the shop like everyone else said. It has to take a decent temp to actually discolor the rod like that.

Re: Is this rod usable? pic
 

I have an actual honest to god associates degree (more than a class!!1) in machining, my second year concentration was CNC not tool and die, but I STILL got to use one of the Lucifer tempering ovens and test for hardness on rockwell scale.

That rainbow ---- = bad.

That, and Brad Z :p

Re: Is this rod usable? pic
 

i wouldnt worry about it, if it plastiguages fine and it isnt warped id still rock it. That discoloration isnt in really in an area where rods typically fail anyway... i mean, ive never seen an endcap fail. If it was badly discolored mid beam then i might worry about it.
