(R) ENGINE FL YWHEEL HOUSING AND MATING TRANSMISSION HOUSING FLANGES
Foreword—This Document has also changed to comply with the new SAE Technical Standards Board format.
刘佳欣
1.Scope—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 transmis
orally
sion 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
crankca rear face or the design of housing walls and ribs. Housing strength analysis and the lection 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.
1.1Purpo—This document is intended to achieve standardization in the design of "Engine Flywheel Housings"
and the "Mating T ransmission Housing" flanges to assure compatibility.
