Air Cleaner

[160B]

FWIW

Ford introduced an air cleaner in September 1932 for the improved 4-cylinder Chassis

There have been many threads discussing air cleaners on Model A Fords. Several state that Henry did not build the Model a Ford with an air cleaner, thus you do not need one. Ohers say they believe that you should run an air cleaner.

Well I recently came upon the Ford Service Bulletin Vol. 13 September – October 1932 No. 4

On page 55 the Bulletin states:

AIR CLEANER

An oil bath type air cleaner, B-9625, is now available through service for installation on the improved 4-cylinder Chassis. The cleaner proper is identical with the BB-9625 air cleaner as described on Page 38 of the July bulletin. For obvious 'reasons, however, the method of mounting on the B Chassis differs. Fig. 87 illustrates the method of mounting this new cleaner to the forward side of the dash. A study of this illustration will indicate what constitutes correct installation. When installing this cleaner on cars equipped with the B-6850 speed governor (see Page 39 of July Bulletin) the difference in the position of the carburetor is, taken care of in the upper rubber hose connection as indicated by the dotted line (see Fig. 87).
