Help identifying my exhaust brake on a Catapilar C7 350

Good morning, 

Please see attached photos. Can anyone tell me if this is my exhaust brake on my Catapilar C7 engine?

Probably, but you need to look at the top of it. I have attached a photo of the top of a Cat C7 engine with the exhaust brake on the lower right. It has the shiny silver cylinder with the lever.

Pretty sure in your last picture it’s on the right and you can see where it goes in between the exhaust and turbo.

Hi Dr4film,

Thanks for your reply. I found the exhaust brake module. How do I lubricate it? I think it is frozen because nothing moves when the exhaust switch is on and the engine running. How can i tell if it is operating properly?

It will not be active until you are above 15 mph. It shuts off at 15 mph.

The best way is to add a toggle switch to the relay that activates the cylinder. Then you can close and open the valve at will.

Look up the manual for the PacBrake Exhaust Brake to see exactly where all of the lubrication points are located.

Then use a good lubricant, either the one suggested by PacBrake or Tri-Flow is also an approved lubricant.
