OUTER PLATE CS SCREW TYPE
Outer clutch plate for the screw-type clutch assembly, catalog PN 57-1724 (legacy T1724).
The 57-1724 is an outer clutch plate for the screw-type clutch setup, sitting in the primary side of the engine as part of the clutch assembly. It's one of the components that make up the clutch pack, appearing in the parts book under the CLUTCH figure. The older-style part number for this one is T1724, so if you're working from an early parts book or a bike with older documentation, that's the number you'd see printed there.

This one shows up in the catalog tied to 1968, and it's specific to the screw-type clutch design rather than the later diaphragm-spring setup, so it's worth double checking which clutch type is on the bike before ordering.
If you're rebuilding a clutch pack from this era, it helps to have the whole assembly in front of you, since plates and springs from different clutch designs don't mix and match.
