If you need instructions and wish to adjust you will need Kent's VCV adjusting kit that includes the needed vacuum guage as well as complete tuning manual on diesel automatics. This 120+ page manual will cover other shift related topics as well. You will also need to make sure your diesel has a strong and leak free vacuum system for this valve to work properly.

WARNING: YOU MUST LOOK at your existing VCV BEFORE ordering this part. There is no guarantee this may fit as someone may have installed a later model engine or made other modifications to your injection pump. Look at the arm coming off your VCV. It must be straight and look exactly like the one pictured. If yours has a curved arm coming off the valve to hold the rod then this part will NOT work. DOUBLE CHECK BEFORE ORDERING!
