WTB M110 Connecting Rod and Crank
280CE spun a rod bearing, machinist is on the fence about the crank, so if you've got some of those, I'd take that too.
But I definitely need at least one connecting rod for a M110. The car is a USA Spec M110 1978 280CE. Google says 75-81 is the same but it only lists it as being for fuel injected models. Maybe someone else can confirm or deny fuel injection vs carb compatibility.

To the best of my knowledge, all US M110s, 1973-85, W114/116/123/126, share the same short block. Cylinder head differs between carb & inj. only in drillings for injectors.
Consider sourcing a short block; there are many M110s around. |

I have a complete euro M110 and a complete carb 76 280C motor. I didn't want to tear a motor apart just for one rod. But if I need a crank and the parts are the same I'll tear down my 280C motor for the guts.
The 280CE is a low mileage exceptionally original and rust free car, so I was attempting to keep the original block. The cylinders look great and it ran really well. But for whatever reason it lost a rod bearing, but being a 78 and only being in my care the past couple years I have no idea what happened to it for the prior 30 years.

I'm pretty sure the rods are the same, although the fuel-injected pistons are not the flat-top items in the carbureted engines to my knowledge.
I've actually replaced a couple of M110 pistons and rods from below with the crankshaft, block and head remaining in place. If the rod journal isn't too banged up and your mechanic is creative it might be feasible to drop the oil pans and install a new rod and bearings--mine lasted until the whole engine needed rebuilding--good luck Tim Kraakevik kraakevik@voyager.net |

Tell us who you really are. Are you Sigfried? Are you Roy? Are you David Copperfield? The span between main bearing webs of the 110 block is ~68.5mm. The diameter of a 110 piston is 86mm. How did you get 86 to pass thru 68? And with the crankshaft in place also! Slight of hand, indeed. |

The head must have been off--the two pistons I replaced were conveniently accessible through the oil pan. There might be enough clearance to replace the rods but not the pistons from below with the throw at bottom dead center--don't know whether the piston pin would drop low enough in the bore to fit a new rod.

I pulled my 76 280C into the garage this weekend and pulled the motor and stripped it down. Crank and rods headed to the machinist who has the CE block.
Thanks for the info guys!
