My customer has a WA480-6 S# A48038.
The machine has an E03 CA324 error code for a #3 injector open or short. Now I have a few questions so I know how to approach this........
1. How has Komatsu been on their reman'd injectors? I usually wont even consider rebuilds as I haven't had good luck with them overall.
2. Is it possible for the injector coil to throw this code? The problem has been erratic (according to Komtrax its coded this 17 times since May 26th) I ran the machine this morning and couldn't get the code to come up....typical.
3. Are these injectors plug and play? or will they need calibration after install?
4. The operator states that he cant tell a difference in the engine power or operation when the code and alarm are going on.
I would think there would be a dead cylinder and should be very noticeable. Not something I would think a failing injector would do.
5. The engine has several exhaust leaks..at the manifold ports on #5 and #6 .......and also the turbo exhaust housing where it bolts to the bearing case. I dont believe this is related in any way to the error code above.
The reason I need this info is because the engine has 17473 hours on what looks like the original injectors, and possibly the original pump. The customer has very little info on past repair records so I am not absolutely positive on this. Normally I would do a diesel tune on an engine with 10-12k hours by running the overhead, replacement of all the fuel injectors and the pump, and I usually would replace the injector wire harness. This is a difficult sell for a customer that believes their engine is running fine but,......their PM is abysmal and the fuel system has had water run through it numerous times in the past.
I'm not sure I want to just do a simple repair and not advise the customer of what should happen at this point. What has been you guys experience on something like this?
