Screw (1/4-20 BSW x 15/16 in., cross head)
A 1/4-20 BSW cross-head screw, 15/16 in. long, used across crankcase, gearbox, and chaincase assembly work.
This is a small cross-head screw, 1/4-20 BSW thread, 15/16 in. long, listed in the catalog under part number 70-3437 (also shown as E3437 in older references). It turns up across several areas of the engine and gearbox assembly work — crankcase, gearbox and casing, and chaincase and alternator sections all call for it, so it's one of those fasteners you'll want a few of on hand rather than just one.

Because it shows up in multiple figures rather than one specific job, think of it as general assembly hardware for this era of engine rather than a single dedicated fastener. The catalog ties it to appearances from 1960 through 1962.
If you're missing one during a rebuild, it's worth grabbing a couple extra since the same screw does duty in more than one spot on the same engine.
