Chevrolet 1533X2 30-cwt trucks

[Colin Alford]

Charlie,

The Chevrolet tire pumps started with the ‘inverted v’ air intakes, then transitioned to the air cleaner. The 1543X2 parts list indicates that the air cleaner was fitted to “after jobs”, but there is no indication of an exact serial number.

Attached are 4 images. The first two are from the 1543X2 parts list (as discussed before, Chevrolet used many “standard” illustrations in their parts manuals and while this shows the Control rod which is actuated through the floor of a CMP, I am quite positive that this is incorrect for the 1543X2 and 1533X2). The third and fourth images are from the CMP Parts lists C8A-04, and C30-03, to illustrate that the tire pump air cleaner is the same as the transfer case air cleaner. On both the C8A, and C30 the transfer case air cleaner was added in 1942, but i do not know if this would have coincided with air cleaners being added to the tire pump.
