Turbo check

[ltlbo]

I don’t think my whistler is working how do I check/test it?

 

[doghead]

What indicates that it is not working?

 

[Jeepsinker]

Let the truck idle until it is warmed up, then gently rev the engine. If it whistles it is working.

Thinking boost gauge here.
Chapter 2 section 4 of the TM 9-2320-361-20 has engine troubleshooting.
Also refer to TM 9-2815-210-34-1 for troubleshooting maps for the multifuel.

Is it a C turbo or D turbo? Not all Deuces have Whistler Turbos. The C's are the Whistler Turbos, the D's are Non-Whistler. It has been said the D's are more durable than the C Turbos.

The D turbos are also much easier on your ears than the C.

Do a search for " C or D turbo" dozens of threads will come up.

This isn't important right now. Re-read post 2. What are the symptoms? Share why you think it's not working if you want answers.

You can also pull the inlet pipe off of the turbo and see if the shaft spins freely (truck off - of course).

You can also idle it until warm and shut it down, then listen for the turbo as it spools down.

Turbo's are really simple units. So I would take the pipes off the intake and exhaust sides and physically inspect it for damage. Also check for movement in the shaft. It should have a few thousandths play but not more. If the vanes are not damaged and you see no signs of oil leaking, then I would bet your turbo is fine. Then I would inspect the exhaust side for leaks and then the intake side for leaks. If the pressure is leaking off you will have the same effect as a bad turbo.

This is a sign of a bad turbo !
