I tore into my shortblock this weekend for my puller project. It is an 89 or 90 12v. The rods are from Japan and have the large counterweight on the cap. I have searched through the many connecting rod threads, but I have not found anything specific to these.

Does anyone have any info to specific to these rods?
 
I'm not 100% sure ,but i think cummins parts made in japan are marine parts. good luck with the build.
 
I have seen USA made rods in marine engines.

Japan rods are OK, they are almost identical (visually) to US rods, England rods are sightly different.


I have disassembled few industial engines with Japan and US rods, England rods are from my 98 12V
 
AsTroSS said:
They are better than CR rods and we all knew CR rod limit is approx 800-900 hp

Yeah I know..probably should have been more specific in my wording. Trying to get a feel if they are worth using in a high hp application or if I should look for a set of USA (or other) 12v or 24v rods (non-CR).
 
ha and you guys talk about duramax's being jap motors.

i've yet to pull apart my 91 motor to see what's inside.
