Description / Abstract:
This SAE Standard specifies the major dimensions and tolerances
for Engine Flywheel Housings and the Mating Transmission Housing
Flanges. It also locates the crankshaft flange face or the
transmission pilot bore (or pilot bearing bore) stop face in
relation to housing SAE flange face.
This document is not intended to cover the design of the
flywheel housing face mating with the engine crankcase rear face or
the design of housing walls and ribs. Housing strength analysis and
the selection of housing materials are also excluded.
This document applies to any internal combustion engine which
can utilize SAE No. 6 through SAE No. 00 size flywheel housing for
mounting a transmission.
Purpose
This document is intended to achieve standardization in the
design of "Engine Flywheel Housings" and the "Mating Transmission
Housing" flanges to assure compatibility.
