Replacing a Fuel Injector on the Detroit 6V92

When you look at the top of the cylinders, you will be able to see three rocker arms for each cylinder. The two outer ones operate the exhaust valves, and the center will operate the injector. This one that operates the injector will be slightly longer on one side compared to the others. These arms move on a shaft that has two brackets, and removing these brackets allow the rocker arms to be raised and then access the fuel injector.

A step by step guide is below:

Step One: Remove the valve rocker cover and discard the gasket. Then, locate small tubes going into the injector and the fuel connectors and disconnect them.

Step Two: Bring the injector and the valve rocker arms in line horizontally by cranking the engine. Remove the two rocker shaft bracket bolts and move the rocker arms away from the injector and the valves.

Step Three: Locate the injector rack control lever. Loosen the screws holding it in place and slide it away from the injector.

Step Four: Lift the injector from its seat and cover the hole to keep dirt and debris out of the cylinder head.

Step Five: Install the new injector and tighten with a torque wrench to 27.12 N • m or 20-25 lb • ft.


Changing the Oil Filter

The Detroit 6V92 engine absolutely needs clean oil in order to keep functioning as it should. The good news is, keeping the oil clean is a relatively easy process, by monitoring and replacing the oil filter every 1000 hours of operation. Here are the steps:

Step One: Inspect the shell, or outer part, of the filter. If it is obviously damaged, the entire unit should be replaced. Remove the drain plug from the bottom of the filter shell. Drain the oil.

Step Two: Locate the center stud, a long bar that runs the length of the oil filter. Remove the shell, element, and stud from the engine. Throw the element and shell's gasket.

Step Three: Remove the center studs and the gasket. If the gasket is not damaged, it can be reused. Locate the element retainer seal. Remove and discard it.

Step Four: Using the filter removal tool, take the filter out and throw it away. Remove the bypass valve by taking the screw/retainer or plug/gasket off.

Step Five: Clean the filter shell and base. The bypass valve can be cleaned in fuel oil.

Step Six: Install the center stud gasket and slide it through the filter shell. Install a new shell gasket, and put a new element over the center stud. Replace the drain plug.

Step Seven: Add oil and check the level with the dipstick.
