I know we have always talked about it and I think it may have been has been done before but I have some extra rebuild kits coming from Carrillo. Thier new Cannondale rods already come with hardened inserts and wrist pin bushings. Since I have a stroker crank that wore out a z400 bearing causing the rod/pin to become unusable I figure it would be a perfect stress test for these rods. Brian Kinney has been the local goto guys for z400 updates and like Tim settles for nothing less than perfection . He has been chompin at the bit to build a stroker crank so here is his chance.
I was a little worried about these new rods so I told them to build the rods to handle 12,500 rpm minimum . I didnt talk to the engineeer after he ran the design through the structural analasis program but he didnt think the OD of the big end will have to be larger but Tim thought we could go another .020" if need be. Other than the rebuildabilty they should be a perfect drop in .
The engineeer said they might rebuild worn out stock rods but only ones that were original Carrillo rods and not the forged ones from Mappe. He said the forged ones I sent them had to much variation in big end thickness to risk rebuilding. And used rods could not have heat stress or side wear. Thier price to update used rods seemed a little steep and Tim said he could do it no problem so i thinki will let him do the first ones. The problem is I dont have any more used rods..... Anybody got some Carrillos laying around?
rebuild connecting rods
The Carillo's (early cranks) were H-beam profile. If I spot a pic around, I'll post it.
Edit...
Here's half of one that may or may not be Carillo:
Billet Rod
The guy paid extra for this version!

The rod I have at Tim's is an H-beam. I didn't realize Carillo built them for cannondale.

Forgive me for still learning, but which rods are which? I have an early FX rod at Timbos now that lost a bearing (tim said crank had cranks leading out from the pin but rod could be salvaged), and I have an '02 crank with a bad bearing too.
Tim said your crank was junk but he could resleeve the rod.
Here's an interesting note. Carrillo lost the work files for the original rods so I had to send them some samples( perhaps a Timbo Rod
). They also did the Winky narrow versions where he was putting in the thrust washers.
