Looks like a 1700/1800 Conrod according to the Tom Wilson book

Hi Mark

What is the ID of the bush where the gudgeon pin goes through? You get 2 different 1700 rods that utilize different pistons.

NO IDEA SEAN; I'LL HAVE TO MEASURE.
I ASSUME FROM YOUR QUESTION THAT THIS IS INDEED A 1700 CONROD THOUGH......
WHAT IS THE DIFFERENCE IN THE PISTONS AND WHY?

That appears to be a 1700, but it’s only based on a picture. Measure it to know properly.

@ SEAN.... AND ANYONE ELSE THAT KNOWS THEIR STUFF.
CENTER TO CENTER 12.5CM (125MM)
COMPLETE LENGTH TOP OF NIPPLE TO BOTTOM OF CONROD 19.5CM (195MM)

If you read the above explanation then you have the tall balancing pad (Square thing on top)

So you have the 1700 con rod

The 1800 has a small bump balancing pad on top, as per photo, which you have not got.

Here is a pic below of 3 different rods I’ve taken. 1.7, 1.8 and 2.0.

I'M FAIRLY SURE MINE IS A 1700 BUT THE ENGINE/BITS WAS/WERE SOLD TO ME AS AN 1800, HENCE THE UNCERTAINTY.
I DO REALISE THAT A LOT OF PEOPLE DON'T KNOW TOO MUCH ABOUT THESE THINGS.

As most books will only give you a guide, you will have to measure and measure and measure to make sure you have the right collection of parts to fit into one engine.

As so may hodgepodge motor's are out there with a mix and match parts list, you can not be sure what you have without measuring.

Good luck old boy.
