I need to replace all 8 of my electric injectors 523-4775 as some are leaking fuel into the cylinders and diluting my oil. I have all Reliabuilt injectors and need to know if there is anything special I need to do after I replace all of them. It looks like I only need to remove the 2 fuel lines, 2 wires and then remove the 2 rocker bolts that hold it in at which point I can remove the existing injector and insert the new one, install the rocker and tighten the bolts to 90 fp, install both fuel lines and wires.
The engine runs fine now with plenty of power and quick response.
The side decal does show my injector timing is 1.520, so not sure if I can just replace the injectors since they are electric or is there additional steps I need to do?
Thanks for any assistance.

You are going to need the timing tool to reset the injector height and the service manual to do the sequence.I have 6V92TA in my coach but have not had to go into it yet. I have done it on my series 60 in my big truck though.

Thanks Stump, but if the engine is running well now and the only reason I am changing the injectors is due to some leaking fuel into my oil, do I need to mess with resetting the height?
I do not see anything I can adjust related to the injector. Only the intake and exhaust valves have adjustment screws and lock nuts.

It looks like I only need to remove the 2 large bolts holding the individual cylinder rocker assembly in place, remove the old injector and insert the new one. Remount the rocker assembly and torque to 90fp.

Am I missing something as I want to ensure itis done correctly.

Your 92 is a 2 stroke it doesn't have intake valves. You are looking at the exhaust valves and the injector rocker arms. I'd really look on ebay or somewhere for a 92 series DDEC service manual.

Thanks Stump, you are correct that I was looking at the exhaust valves. There is an adjuster on the push rod for the injector which I can adjust and I do have the 1.520 gauge for setting the injector plunger height.
