#3406C low power

[Dave Neubert]

It was originally built as a DI engine with jacket water aftercooling. Is it still like that.?

yes the specs I got from Cat said 18 psi the one you got is higher

 

[Dave Neubert]

Technically---yes, but I'm wondering which advance this has.

It has a oil pressure advance

Check your messages. I sent you the full 0T spec.

What is the whole story? When did this start to happen? And is that why you did all the work to it?
Maybe the gizmo that the flywheel or pto is hooked to has the problem, and is just over loading it?
This is just more info to think about.
Is the governor responding to the load?
Is pump timed correctly?

I thought I remember the old school advance having an occasional slipping problem, its been so long don't know.

Was working fine then as I was told it started bogging it runs a air compressor should build 350 psi starts bogging at 200 psi with very little smoke timing good governor seems to respond

Came back to let everyone know that a set of OR injectors fixed my problem

 

[Truck Shop]

Plugged--it was great when ATF could be added to fuel. But that red stuff turns a tank red.

 

[Coaldust]

Did the new nozzles bring the boost back to spec?

 

[Dave Neubert]

Yes engine don't drop any RPM under load

 

[Vetech63]

I'm wondering if the injectors are atomizing the fuel properly. How does it start?

Who’s this guy? What a jerk

That's post #6, look at post #3, even more a jerk than you

 

[Coaldust]

I’ve had Cat nozzles kick my ass like that, in the past. Like Vetech63 mentioned. Hard starting is a great clue. We forget about the easy stuff.

 

[cfherrman]

Turbo spools on a load, you can't get loaded up without injectors or compression

 

[Coaldust]

Having the OT spec is so valuable. The service manual is just a guide with generic specs. Nige is a gentleman to provide that info, time and time again.

I don't know what we would do without Vetech & BlueOx, two of the best.

Never suspected injectors started great sounded good no puffing or miss. the governor on the injection pump was wore out so it needed a rebuild anyway

 

[Nige]

So the injectors were just the last piece of the puzzle to get it to run right.?

 

[Truck Shop]

It's why I brought up ATF in the fuel-----Anyone running a stationary should dump a couple
quarts in the tank from time to time. The on road diesel cops won't be checking. ATF was the
common cure for years worked well for unclogging Cat pencil nozzles, plus it was cheap.

The real Vetech--at his second job.
