STUD OIL PIPE JUCTION 5/16 UNF/UNC (USE WITH 21-1908) 70 T120 book error
A 5/16 UNF/UNC stud for the oil pipe junction on the crankcase, used together with part 21-1908.
This is a stud used at the oil pipe junction in the crankcase area, threaded 5/16 UNF on one end and UNC on the other. The catalog notes it's meant for use together with part 21-1908, and flags that the 1970 T120 parts book had an error listing this stud, so if you're cross-checking an older book don't be surprised if the numbers don't line up cleanly.

It shows up in the crankcase section of the parts books and only appears once in our records, spanning catalog listings from the early '70s into 1980. Given how specific this stud is to the oil pipe junction hookup, it's worth confirming you've got the mating part 21-1908 on hand before you order, since the two are meant to be used together.
Also listed under the earlier number S1863 if you're working from an older-style parts book.
