I was wondering if any one knows the sequence to set the valves and injectors on the overhead valve lash settings.

The valve settings are .015 Intake/ .030 exhaust/ and .027 on the jakes. You will also need an injector height tool to set the injectors. If you have the tool, it has a top step and a bottom step, If you set the injectors where the bottom step is sticking out slightly will advance the fuel timing 2 degrees.

mbaker where did you find that the .013 difference between the upper and lower step is equal to 2 degrees of timing difference?

I used to work at a cat dealer and a guy that had worked there for 35 years told me that it was equal to 2 degrees of timing advance. So I just took his word for it. It has always worked for me. All the overheads I have ran, I adjust the injectors that way, and I have seen improvements in fuel mileage and horsepower.

Easy trick... set the exhaust lash with the intake just opening & set the intake with the exhaust just closing. this makes sure thath you are on the base corcle of the cam while setting lash. Also, 2 flats on a hex nut, 120 degrees = .015" & 4 flats, 240 degrees = .030". Just an alternative to all the feeler guage & degree of drage stuff.

Brake
SMCS - 1119; 1129
The Electronic Control Module produces high voltage. To prevent personal injury make sure the Electronic Control Module is not powered and do not come in contact with the fuel injector solenoid terminals while the engine is running.

This engine uses high voltage to control the fuel injectors.

Disconnect the fuel enable circuit connector to prevent personal injury.

Do not come in contact with the fuel injector terminals while the engine is running.

The engine valve lash and the injector lash must be within specifications prior to adjusting the compression brake's slave piston lash. Refer to Testing and Adjusting, "Engine Valve Lash - Inspect/Adjust" for the correct procedure for inspection of the engine valve lash. Refer to Testing and Adjusting, "Electronic Unit Injector - Adjust" for the proper procedure for inspection of the injector lash adjustment.

Note: The slave piston lash adjustment must be performed while the engine is cold. If the engine is warm, allow the engine to cool prior to performing the following adjustments.

Use the following procedure to adjust the slave piston lash on cylinders 1, 3, and 5:

Put the No. 1 piston at the top center position on the compression stroke. See Testing and Adjusting, "Finding Top Center Position for No. 1 Piston" for further details.

NOTICE
Prior to adjusting the lash setting for the engine compression brake, check the identification plate that is on the compression brake's casting in order to determine the model that is installed on your engine. You must have this model number and the engine's serial number prefix in order to determine the lash setting for your engine.

( 1 ) Check the identification plate that is on the compression brake's casting in order to determine the model that is installed on your engine.
( 2 ) Some of the early 3406E Engines, 5EK1-01820 were built with either the 340 or the 340A compression brakes.

Note: The slave piston lash settings are specific to the model number of the compression brake and to the serial number prefix of the engine. Use these settings only for the compression brakes and serial number prefixes that are specified in the table.
