BSA Gudgeon pin
A gudgeon pin (piston pin) connecting the piston to the connecting rod small end, cataloged as 68-0263.
This is a gudgeon pin, listed under 68-0263 (also shown in some records as 68-263). It's the pin that runs through the piston and connects it to the small end of the connecting rod, letting the piston rock slightly as it moves up and down in the bore.

Our catalog record places this one in the crankshaft figure grouping, which is common for gudgeon pin listings since the pin ties the piston assembly back to the rod and crank. The catalog entries we have for this part span 1969 to 1970.
The description on file is brief and doesn't spell out diameter, length, or material, so before you order, have your piston and rod on hand to confirm fit. Call the shop if you want us to double check against what you're rebuilding.
