Hello,
Could anyone help with dating my gearbox please. I have been online and cannot find any models of Burman that look anything like mine. I have a bad oil leak from the gear selector bush and wondered if I could remove the front plate safely without all the internals jumping out!
The gearbox is marked AU/520/0/L642
Thanks and regards
John.
Sounds like a Sunbeam box from 1934/5 Can you post a picture?
Vic
Thanks Vic,
Hope you can see enough of the gearbox on this shot.

John
Definitely a Sunbeam box and likely to be 4 speed.
Vic
Thanks Vic, it is a 4 speed.
Is it good news that its a Sunbeam gearbox rather than a Burman? Are selector shaft seals available to purchase anywhere, I have quite a leak from mine.
Thanks, John
do you mean where the operating arm fits the gear selector shaft on the outside of the gearbox?.
My understanding is that there should be a leather washer under the large hollow nut and that gets tightened to compress the leather to form a seal..John
As everyone has said, this is a Sunbeam 4-speed box. The AU 520 series first appeared on the 1935 Model Year machines, and was used on all models.
Sorry for late response, but I've been away.
