1946 – 49 Triumph Pre-Unit Rigid Frame gearbox 500cc 650cc T264A SM1040

1946 – 49 Triumph Pre-Unit Rigid Frame gearbox 500cc 650cc T264A SM1040


Post war Triumph Pre-Unit Rigid Frame gearbox 500cc 650cc T264A SM1040.

Thunderbird, 6T, T100, 5t, Speed Twin etc, as long as they are the rigid framed variety. It should fit the 3T Deluxe too.

The main case has a cast number T264A, placing it between 1946 and 1949. The main gearbox casing has a number is TE101403. According to the records, this gearbox was supplied on Sept 1949 although it was paired with a 1948 frame and T100 engine.

T264 seems to be just prewar and T264A / B seem to be post war. By 1950 the cases had T909 and T910 on them. So, I guess the part number for this one is 57-0264A. Please refer to your parts list before believing a word I’ve said here. The inner cover is T410 and the outer cover is T411.

The box has the selector indicator, the gear cluster and more. Please have a good look at the pictures. Ask questions if you need more info. The main case appears to be undamaged. there are no cracks that I can see. The two mounts are good for a change and even the clutch cable guide / adjuster mount is intact.

This is being sold as a gearbox needing rebuild, as I haven’t touched it. It turns fine. But it will need to be taken apart, cleaned and re-assembled. Some parts have a very light amount of surface corrosion.
