117 – Oil Filters


All oil filters used as standard equipment on 1940 74 and 45 models are so constructed that if care is not taken at installation, it is possible to install them backwards.

One end of the filter, in raised letters, is marked “INLET”. This inlet end must be attached to the oil pump line.

We would suggest that all machines entering your shop be checked to see that the filter is properly installed.

Filters installed backwards will slow up the return of oil to the tank and, in some cases, blow apart the filter as well as cause an accumulation of materials on the sump-screen and in the oil pump.
