Truck Repair: Cummins NTC300

Question
Hi Jeff, I have a NTC300 with model 400 jake heads, two are damaged and I have a set of model 30E jake heads, are these interchangable? Cheers

Answer
According to the Jacobs brake website they are interchangeable. I myself have never tried it so I can't tell you for certain if everything is a direct bolt up. Don't know what you mean by damaged but they are rebuildable if you wanted to go that route.
