Screwed pin (1 19/32 in. U.H.)
A screwed clutch pin (1 19/32 in. U.H.) for the clutch assembly, later superseded by 57-4754.
This is the screwed pin used in the clutch assembly, catalogued in the parts books as a 1 19/32 in. U.H. screwed pin. It shows up in clutch figures across our records from the mid-1960s, and the earlier books list it under the T423 designation before the numbering changed over to 57-0423.

A screwed pin like this threads into the clutch and gives the clutch spring or pressure plate hardware something solid to bear against. If you're rebuilding a clutch and pull one of these out worn or stretched, it's worth checking the rest of the set at the same time since they all see the same load.
The factory eventually superseded this part with 57-4754, so if your bike came with the later number stamped in the manual, that's the same physical pin under a newer part number. Call the shop if you're not sure which one your clutch needs and we'll sort out fitment before you order.
