Up for grabs today is a new Triumph pre-unit gear box sprocket nut with seal. What makes this part better than using an original nut is that this nut comes with a seal installed.
Now you can stop oil leaks in addition to securing your gear box sprocket. Made and designed in England to replace Triumph part number 57-0440, T0440 and T440. Fits Triumph 650 pre-unit twins (Bonneville, T120R, Tiger, TR6, T110, 6T, etc) from approx 1953-1962.
- Made in England
- Replaces part number 57-0440, T0440 and T440

Needed a part I couldn't locate here in Ireland or the UK. Thanks CBS
I had to enlarge the hole in the inner primary case and the flats are not the same as the stock nut, but well worth the effort. Whoever makes this, THANK YOU!
