G'day All,

I've been busy measuring the weights of my new parts and old parts of my OM617.912 before I start to rebuild it and I came across a bit of a problem.

According to the FSM all the connecting rods used in one engine should be of the same weight group. (See attached photograph for these values)

It also says that each connecting rod has a weight group colour code printed on the inner side of the big end cap... I can't find it there though.

Has anyone come across this before? Does anyone have a picture of a connecting rod and its colour code?

(I'm guessing it is just like the time I couldn't find my rear diff ratio - so someone please give me a cyber kick up the backside)
