5、Superseding J617 MAY2012 Engine Flywheel Housing and Mating Transmission Housing Flanges RATIONALE Users of the document have identified an error in Table 1 for the OO housing pilot diameter nominal dimension. The inch dimension was correct but the millimeter dimension was wrong. 1. SCOPE This SAE S

6、tandard 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 int

7、ended 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

8、 No. 6 through SAE No. 00 size flywheel housing for mounting a transmission. 1.1 Purpose This document is intended to achieve standardization in the design of “Engine Flywheel Housings“ and the “Mating Transmission Housing“ flanges to assure compatibility. 2.
