which shows an easy way of doing this by simply removing the bolt, sticking it in backwards, and giving the bolt a decent whack on a table (or other wood surface) to pop the ferrule out. The problem is that, unless you stick some sort of cushion in there (like a split piece of rubber hose), the head of the bolt makes sharp contact with the cracked surface when the ferrule pops out. And, of course, this guy made no mention of using any type of cushion. Here is what happened to the cracked surfaces on my rod cap:
. As you can see, the fracture surface was nicked, and I am not sure whether material simply broke away (not really a bad thing) or whether it deformed (a BAD thing, as it would prevent proper mating). The cap seems to bolt on OKAY, but it is hard to say. I am unsure whether this will affect bearing clearance and/or cause the cap to ‘settle’ with time, effectively loosening the bolt. Am I overthinking this, or is there the potential for problems here?

Bolt the affected caps (all of them maybe?) to their matching rod, with the new correct torque number, and mic them. You may, or may not find a little distortion which will require a quick clean up hone at a shop. This is the only way to know for sure where you stand. No way I’d just throw em in and run it not knowing.
HI ALL, I would like to know the cost of ARP rod bolts AND a rod resize with the Low Performance AL rod bearings required for an O/S rod housing bore for use in "honed" rods ?
The TOTAL COST.
My gut feeling says no. Why risk it when another set of stock rods can be had for CHEAP.
The purpose of the cracked surface is to maintain alignment between the two halves. With the surface compromised, the engagement of the peaks and valleys is going to be limited and therefore provide less lateral support.
In for the response to Lance's question. OP, presumably this happened to only one rod cap. Pick up a another rod w/cap and have it honed, you'll have to do the whole set anyway to use the arp bolts.

Actually, it happened to three rod caps before I discovered the problem. After that, I removed the ferrules on the remaining rods the same way, but put a very short section of rubber hose split down the middle over the bolts to prevent contact between the bolt head and rod cap. This did the trick. What’s REALLY amazing here is just how LITTLE it took to damage the fracture surface like that. It’s not like I was hitting those caps THAT hard on the surface to remove the ferrules.

GOOD Pictures Matt, thanks for your good work !

Lance, you can get a Clevite “H” series bearing in .001” oversized, which is a high performance steel bearing. But I know what your trying to say. You can pretty much get into a budget steel rod for the same price as a complete rod hone, the super expensive bearings, and the good bolts.
You could take a hand grinder with sandpaper cartridge roll to dress down those tiny nics preventing improper fitment. Then a good shop can hone those big ends just a few strokes to straighten the out of round while still staying in spec for good bearing crush.

The only problem is that, if you are talking Scat Rods, they don’t have a 6.098” version (.944 pin) that uses a floating pin. You are stuck with pressed.

Lance sells steel rods at a VERY affordable price...
Not real sure what brand they are however.

Summit has the 8740 rod bolts for $95 and the Clevite bearings for $24. Machine shops costs will vary, but my local machine shop charges $40 to resize all 8 rods. So call it $160 total cost.
Hi Scott, thanks.
There are TWO ROD factories in Shenzen, China.
The are NEXT to each other as I have been there.
The Eagle side is one AND the other side is the Callis, Scat, Pantera, etc. side of production.
Thanks KCS, though you forgot the cost to "press" the pins both in/out ?
I supply my Forged Rod (ARP 8740 USA Honed) for $400.00 to your DOOR (USA)
This Forged Rod ALLOWS for King Race Bearings, NOT the CHEAP Clevite NON-RACE Bearing, JUST be fair to all.
There is NO CONTEST, if the standard Clevite bearing is fitted, non-race, the bearing clearance could too SMALL.
MY POINT is WELL TAKEN by some here, the "cost difference" is LESS THAN $200.00, the UPGRADE to a Forged Rod !
