I have a 1916 Cole 8. The engine is a Cole-Northway creation, and it requires new connecting rods. They are 9 1/2" long(c/c) and are of a fork and blade arrangement . See photos

Any information about new manufacturing would be appreciated.  If other owners are interested in replacing them, please advise.

I might have an extra set.  I am restoring a 1919 and 1920 Cole...see my thread under Restorations.  I have a few 1916 parts, but they are mixed in with everything else, as the 1919 was completely disassembled when I bought it.

Well I’ll be. Did other makes do this? I know some Radial aircraft engines did this. 
is the Cole pressure fed ? Must make for some interesting crank wear and some talented bearing scraping.

Not familiar with any of these V8s, but FWIW:

(1) Looks like Cole used the same engine 1916-24 per thunbnails in Std Cat V8 1906-2002, which should be named Std Cat Mainline V8s, as has pitifully little on the 1915--20s orphans... one parts catalog lists a different V8 for 1915, not mentioned in Std Cat V8s...

(2) if Cole rods above don't work out, may be worth checking the Olds 17-23 rods; piston is different but  rod bearing is very close (parets co's 1217,1217A, 1218 for these Olds and Northway engines...

What is wrong with the con rods you have?  They can usually be straightened or resized if necessary.

 

Malcolm and I have been in touch, even though he's halfway around the world.  The engine overheated with resulting damage.  inspection revealed cracked connecting rods, among other problems.  He's having new ones machined.

Those have to end up being very expensive replacements ! So much metal to remove on the fork rod. { I am assuming they will be machined from billet rather than a forged blank like the original ones. }  No decent, used rods anywhere ?

 One of the models of British genset engines I used to work on a lot used rods of this type. But quite a bit larger . They were developed as a  dockyard switcher locomotive engine in the late 1940's . Everything on the engine was designed to be as compact as possible . Paxman RPH.

This is a later ; 1960's Turbo version. But you can get the Idea of how compact the engine was intended to be.29628346401_43d7d187b5_b.jpg
