When they were fairly new 88-92? Cummins had tooling to remachine the housings and install different stats. We sent company trucks in on warranty. They were running hot. It was very important to get the numbers off the old stats and replace with the same normally. Cummins used to be much more friendly here. They would come out and cut counter bores. Install upper deck or cam bearings sleeves sleeves. That is a thing of the past.
I think a loy of that "unfriendliness" has to do with the amount of money the company has lost on warrantee repairs on EGR coolers, VGT turbos, and aftertreatment products, the profit margin has to be getting pretty thin.
