Triumph Pre Unit Rigid & Sprung Hub Frame gearbox Speed Twin Thunderbird 6T 5T T100 motorcycles – SOLD


Triumph Pre-Unit Rigid Sprung hub / Frame gearbox.

1950-54. Please have a good look at the images. I’m not aware that they changed during those years. The main case has a cast number T910 – SM. The gearbox has a number is 30196NA. Before the casting number T910, the rigid Triumphs had a very similar gearbox with casting number T264, T264A, T264B. To my eye, they all look the same. Perhaps the ratios were different?

T264 seems to be just prewar and T264A / B seem to be post war. By 1950 the cases had T909 and T910 on them.

Condition. The box has the selector indicator and the casings are OK and free of cracks or welds.

The clutch adjuster mount is in good condition. (They are usually broken). It comes with the clutch arm.

Both mountings are good.

It turns over freely and the threads on the gear spindle are good.

The sprocket could do with replacing.The teeth have a bit of whip.

Overall, this is a nice rigid Triumph 500 twin / 650 twin gearbox. If you happen to have a Triumph Speed Twin, Thunderbird 6T, 5T or  T100 motorcycle, then this rigid frame gearbox is a good choice.

It’s being sold as a gearbox needing rebuild as I haven’t touched it even though it turns fine.
