Hi Don, there is another key piece of information you need in order to get your jake lash spec. What is the model of the jake brakes on the engine? example: 340B.

The model # is stamped on an ID tag on the engine brake under the valve covers. I can help you if you post that information.

Sorry for the late reply Don. The lash setting will be 0.030" if you have a 435 or higher horse power rating and 0.027" if you are under 410 horse power.
