In the early spring 1976 I was in training as a Heavy Duty Mechanic. The Caterpillar service manual that was applicable to the Caterpillar engine we were using as the class 'guinea pig', gave a part number for break in powder, and immediately following that number was the words (Bon Ami) in brackets. Thats right, plain old ordinary household Bon Ami.
I can't remember what engine it was other than it was a Caterpillar stationary engine and the service manual was Cat as well, not some after market I&T type.
We didn't employ the process on the engine. The instructor just though we'd get a kick out to of the fact that Caterpillar sold Bon Ami under a specific part number.
