Oil pump stud

An oil pump mounting stud for the timing chest, listed under the oil pump/release valve/manifold and tappets figure for 1971.

PN · 21-1684

This is a stud that holds the oil pump in place in the engine's timing chest area, listed in the catalog under the oil pump, release valve, manifold and tappets figure. Studs like this thread into the crankcase and let the pump housing be drawn down evenly with a nut, keeping the pump seated and its mating surfaces sealed against oil pressure.

The catalog shows this one appearing in a single listing, tied to the 1971 model year, with the older alias number S1684 also referring to the same part. If you're chasing this down for a rebuild, it's worth having on hand since a stripped or corroded stud can turn a simple oil pump job into a bigger headache.

Give us a call if you want to confirm this is the right stud for your engine before ordering — the record we have is brief and doesn't go beyond the one catalog listing.
