Sherman / Grant Air cleaners ?

[Colin Alford]

Andrew,

GM Diesel used a few different styles of oil-bath air cleaners, but those used for commercial engines with single or dual air-intakes generally have a protruding flange which interferes with their fit on the military triple air-intakes.

Attached are some images from a couple of GM 6046 manuals with the early (small) and later AC, and Donaldson types.

The last image is a GM 6046 engine which I believe is displayed in a French museum ( images was copied from the internet a couple of years ago, proper credit unknown). It shows the interference issue with a mix of military and commercial air cleaners on a triple air-intake.
