Hi guys  my 3516b is now on 19,000 and going hrs i haven't done any head changes or valve clearances the engine are maintained on time, however i have notice that one of the engines is starting to sound like a misfire@ around 9-1100 rpm can you all give me any suggestions it will be deeply appreciated ! Thanks....:robothappy:


No valve clearances? might be a starting point. You need to be looking at the fuel consumption and load factor as you are probably due a top end overhaul.

Did you check if your air shutoff valve has been released?

Hi achillard ,

 

what is your engine prefix/number and application? The test may vary, depend on it.

Re: Cat Electronic engines

Yes Dave

I always do that before replacing the faulty injectors, otherwise I would not know which one is bad. My question is to know how to analyse the reading from the 1-Cylinder Test. Sometimes, the faulty injector from the 12-Cylinder test has it reading between other good injectors values and that confuses me and I want to know the meaning of the reading from the single cylinder test.

Thanks for the contribution.

Achille

Re: Cat Electronic engines

Just go to "diagnostic tests" , then "cylinder cutout test". The selections will be "1 cylinder cut out" and "12 cylinder cut-out". Select 12 cylinder cutout and then "start". The test will run through 2 passes of checking each cylinder and will display "OK " or "not OK".
