Eagle con rods


Chris Wilson

Recommended Posts

Just doing an engine build for a customer who supplied his own bits. Out of six Eagle rods the little end bushes have a vast range of sizes, some need honing (too small) some need new bushes, or binning, (too big) One has a big end bearing bore undersize, one oversize. I have my doubts about whether the ARP fasteners are kosher, too. What a POS. Now everything's on hold and the balance was a waste of his money. I wouldn't put them in the tractor. Anyone else checked these rods out properly and found issues?

we get emails everyday selling copied kits from eagle, brian crower, carrillo etc etc..

 

they are made in china and passed off as real deal, there was even a USA company saying they were warehouse distrubitors offering me the kits for cheap money.

 

there is load of USA and other EU traders and ebay selling these copied products.

 

be nice if you could send those back to manufacture that made them (to say its wasnt me that made these).

Genuine Eagle rods are made in China. To be honest there may be nothing wrong with some of this Chinese stuff, they are investing billions in tooling and technology, but in MY engines I put stuff in that I KNOW where it is from, and who made it. False economy otherwise. The UK has a fantastic motorsport engineering choice, and I like to support it where possible.

3grams was the total differense between the rods. i aslo stated that the bearing side and the piston pin bushing was spot on.

 

3 grams is horrendous dude, do you know how much that is at say 7000rpm ??? Also just weighing the rods means nothing, rods are balanced end to end, ie all the big ends need to weigh the same and so do all the small ends, i get all the weights down to within 0.1-2 grams OEM spec is around a max of 1 gram I believe.

Actually i might be abit off. when i bored my 7m i left all my parts to the machineshop for balancing and weight both pistons and rods, dunno as far as i remember it was 3g between the lighest and heviest. but i might recall wrong. or it was for the whole assembly it was 3g however the machiner said it was well in tollerance. might be way off tho. can't really say but the engine worked flawless mechanical wise. and i remember them saying there was no need to machine the rods and the pistons as they where well withing the given tollerance.

 

might have been 0.3g difference then. with eagle rods and cp pistons.

 

yeah i did some reading up Dude and the assembly should differ max 0.5g.
