Norton Stud, Crankcase Top Rear
A crankcase stud for the top rear case joint, part of the engine crankcase and breather assembly.
This is a crankcase stud, the top rear position, listed in the crankcase, filter, breather, and tachometer drive section of the engine parts book. It's a threaded stud that holds the upper crankcase halves together at that rear location, providing one of the clamping points that keeps the case joint sealed under running load.

Our catalog record for this one is brief, just the single listing tying it to the crankcase assembly. If you're matching this up to a specific engine, check the stud length and thread against what's currently in the case before you order, since crankcase studs commonly come in more than one length depending on position.
Give the shop a call if you want us to confirm fitment before it ships.
