Vacuum Pump for Jake Brake

[WayneTurner]

Does anyone have an aftermarket part number

to replace the Cummins part # 3965925 or the dodge part # 5102804AA that

has the proper shaft length for the pulley?

I purchased a Napa # 64-1024 but the shaft is too

short.



Thanks Wayne

the best thing to do is to junk the jacob and go to a bd. we are doing this to all of our trucks the bd has about four times the stopping power of the jacob and its compressor mounts out of the way and it only takes a couple of vacuum pumps to pay for a good bd
