Non return valve ball (7/16 in. dia.)

7/16 in. diameter non-return valve ball for the crankcase oil circuit, also listed as E8750.

PN · 70-8750

70-8750 is the non-return valve ball used in the crankcase, a small 7/16 in. diameter steel ball that seats against a machined orifice to control oil flow through the lubrication circuit. It shows up in the crankcase figures for the 1969-1970 catalog years, and is also listed under the older E8750 form for shops working from an earlier parts book.
