ROTOR NUT-T140 1971-82
Alternator rotor retaining nut for Triumph T140/TR7 750 twins, PN 21-2182.
PN · 21-2182
This is the nut that holds the alternator rotor onto the crankshaft end on the unit-construction 750 twins. It lives back in the CRANKSHAFT AND CONNECTING RODS section of the parts book, and it's a small but important piece of keeping the rotor seated where it belongs so the charging system stays in time and doesn't work loose off the taper.
