Cajunboy1959 Posted Wednesday at 02:41 PM Share Posted Wednesday at 02:41 PM Good morning, Please see attached photos. Can anyone tell me if this is my exhaust brake on my Catapilar C7 engine? Link to comment Share on other sites More sharing options...
Dr4Film Posted Wednesday at 02:54 PM Share Posted Wednesday at 02:54 PM (edited) 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.

Craggar Posted Wednesday at 03:56 PM Share Posted Wednesday at 03:56 PM (edited) Pretty sure in your last picture it’s on the right and you can see where it goes in between the exhaust and turbo. Edited Wednesday at 03:57 PM by Craggar Link to comment Share on other sites More sharing options...
Cajunboy1959 Posted Wednesday at 11:15 PM Author Share Posted Wednesday at 11:15 PM 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?

Solution Dr4Film Posted Wednesday at 11:23 PM Solution Share Posted Wednesday at 11:23 PM 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. Link to comment Share on other sites More sharing options...
