This SAE Recommended Practice defines the minimum internal dimensions for clutch housings to provide adequate clearance for single- and two-plate spring-loaded clutches. Consult SAE J617 for housing flange dimensions. Consult SAE J618 and J619 for spring-loaded clutch flywheel dimensions F and G and other dimensional data. Table 1 provides housing minimum internal dimensions for single- and two-plate spring-loaded clutches.
The technical report covers technology, products, or processes which are mature and not likely to change in the foreseeable future.
