11170
O-Ring for an EVO Crank Position Sensor.
Any idea on the size of this O-Ring?

16mm OD x 12mm ID.  2mm cross section.

Harley part number is 11289a.
TC and EVO O-Rings are different sizes.

For future reference for HD-11170
Measured the Sensor and groove to determine the correct o-ring,
Crank Sensor spigot "A" = Ø14.8
Spacer block groove "B" = Ø18.2 x  "C" = 1.3 deep
O-Ring Number 015 (Viton)
(Ø9/16" x .070") I.D. 14.3mm x 1.78mm
