Pacbrake misbehaving.  Help?

<< < (5/5)

LEAH DRAPER:
Any one with a 2008 Cat C9-425, today I finally got the engine hatch in the bedroom between the bed (step) and the closet removed  and looked for an exhaust or engine brake.  Some of you have described it as being very visible at this point.  I could find NOTHING that looked like such a device.
After struggling to get the cover back in place, I decided to read the manual (when all else fails).  I was not able to learn anything more than it is called an exhaust brake that has some integration thru the turbo boost system.  Not being a mechanic that means not much to me.  I could not find any reference as to its manufacturer (Jacobs, PacBrake, etc.)  Nor could I find any reference to any lubrication required for this "beast".

Anybody have any more specific information as to make, type, lubrication needed etc.??  Would appreciate any info/feedback.

Leah,
The exhaust brake that is used on the new engines with a diesel particulate filter like the C9-425, is a variable geometry turbocharger that uses the turbocharger to restrict the exhaust instead of the valve that was used on the previous engines. Since the moving parts on this design are all internal to the turbocharger, there is no visible "exhaust brake" and no lubrication is needed.

LEAH DRAPER:
GERALD,
You such a wealth of information, thank you very much for solving the issue, I can take that one off my "worry list" now.
I sort of got that impression with it's involvement with the turbo but wasn't sure, again THANK YOU.
