DRAIN PLUG 1/4X20X1/2 68-
A 1/4 x 20 x 1/2 drain plug used in more than one housing on the bike, including chaincase and crankcase locations.
14-6101 is a drain plug, thread size 1/4 x 20 x 1/2 as listed in the catalog. It shows up across a few different figures in our records - chaincase and chains, fenders and tail lamp, and crankcase - which tells you this is a small general-purpose plug used in more than one spot on the bike rather than one dedicated bolt.

Because it turns up in multiple assemblies, treat it as a common drain or filler plug rather than a part tied to a single housing. If you're replacing one that's stripped or lost, it's worth having a couple on hand since the catalog shows this same plug specced into more than one location.
Our catalog entries for 14-6101 span 1969 through 1978, so it was a long-running part across that stretch. Confirm which housing you're pulling it from before ordering, since the figure titles show it's used in more than one place.
