Norton Crankcase Halves Assembled
Assembled crankcase halves for the Norton engine bottom end, PN 06-5666.
PN · 06-5666
This is a Norton part, not a Triumph one — it's the assembled crankcase half set listed under 06-5666 in the crankcase, filter, breather, and tachometer drive section of the engine parts book. That figure grouping tells us it's the core bottom-end casting assembly that the crank, filter, breather gear, and tach drive all mount into or around.
