A 10 challenge
« on: 13.06. 2009 15:26 »
About 2 years ago I started to rebuild a 51 A 10 gold flash that I stripped down 30 years ago. Today I found a tin of parts I didn't know I had. They may not all be BSA parts.... if you recognise any in the attached photos can you please let me know what they are? I suspect they will include rear hub parts and maybe clutch parts. I'll be grateful for any clues. Thanks.

Hi Gavin,

The circlip in the first photo is from the rear brake drum bearing cover.

The last picture is from the rear drum brake bearing cover, I can dig up a part number if needed.

The third picture (No 27) also looks like one of the older type fork seals, with the cow hide seal. ( took mine out a couple of weeks ago, guess measuring the ID/OD will answer which one it is ).

How did you go with the air intake hose ?.
