Unsuccessfully trying to upgrade my exhaust brake

[shoalsgary]

I have a 2003 Holiday Rambler Endeavor with Cummins CAPS engine and my exhaust brake is frozen. I've tried soaking in diesel fuel, soaking in PB Blaster, using Bigger Hammer, heat, and NOTHING frees it up. So I want to upgrade to the PPRXRB brake. But every supplier wants the model number of my brake. The only number on my pump is C319 cast into it, but that doesn't satisfy them. Where can I find the model number of my original brake???

It says PacBrake on it. I contacted Pacbrake and gave them the information requested and have not heard from them yet.

Is it possible that your original was made by Jacobs (the Jake people)? They supplied exhaust brakes for some engines of that vintage. I agree with Brett Wolfe, you should be contacting PacBrake directly - they will be able to tell you what part you need better than any dealer or reseller. I have found them to be incredibly helpful.

You talked with PacBrake Corp?

Now I'm trying to find the PXRB that replaces it. I provided my engine number (46248452) and have found nothing on the exhaust brake, original OR PXRB.

Is it frozen because of carbon build-up? Or is it a mechanical issue? If it is carbon build-up try soaking it in Purple Power overnight. $8 a gallon at our local Autozone. Works great for cleaning all things EGR related.

nO CARBON BUILD UP. PROBABLY FROZEN FROM NON-USE.

I think you'll find the S/N tag mounted sideways on the timing cover, kind of behind the inj. pump.
You can use this number to contact Cummins and they can tell you every part that's associated with your eng.
