Replacing diesel injectors...anything else I should do at same time

[ChronicCodez]

I have a MF-230 diesel tractor. I am about to install new injectors. Is there anything else I should do while I am at it? Injectors where professionally rebuilt and pressure set. I have new seals and copper washers.

I am going to be inspecting radiator, water pump and thermostat.
What about injector pump?

This seems like a question that the shop that rebuilt your injectors should be answering. The answer to your question depends on why you had the injectors rebuild in the first place.

Ahh yes of course...sorry for lack of details.
Last summer I noticed a decrease in power over a month or so....bush hogging mainly. I cranked it up one day and heard a knocking, was real sluggish. I turned it off and haven稚 cranked it since.
The injector tips were badly clogged and had some wear so they were replaced.
I am hoping that this is the solution to my problem

My guess is that was you're issue.. I don't mess with injector pumps unless it needs messing with..

How long have you had this tractor? What is the maintenance/service history? Are you certain that your fuel system is clean? Have you ever adjusted the valves?

If it were me I would replace the fuel filter to be sure that only clean fuel is getting to the injectors. I think it is a CAV7111/596 filter on these tractors. Due to the cost of an injection pump i would not replace it. If you still have problems I would replace the fuel lift pump before looking at the injection pump.
