PAC BRAKE'S NEW PRXB EXHAUST BRAKE

<< < (2/2)

Richard And Babs Ames:
http://catrvclub.org/links.htm and call the CAT call center number with your engine SN and build and they will help you.

Gerald Farris:
On coaches with a diesel particulate filter with a variable geometry turbocharger and a regenerator, a Pacbrake is not recommended because the exhaust braking is accomplished by the variable geometry turbocharger. It is computer controlled in combination with the regenerator and diesel particulate filter sensors. If you are able to add a Pacbrake inline after the regenerator, it would have to be coordinated with the emission system to not work when the regenerator is running. There may also be a need to change the programming on the turbocharger. All in all, it is more complicated than it is worth.

LEAH DRAPER:
Want to thank you Gerald for a more detailed explanation which enabled me to obtain more specific information.  I just spoke with a representative from PacBrake about the DPF (diesel particulate filter) and he confirmed that the new upgraded Brake can not and does not work with the DPF ON THE CAT C9 engine.  Very disappointing to say the least.  Guess I'll just have to cut holes in the floor boards and drag my feet!


Again Thanks Gerald!
