Title: BSA steering tube removal
Post by: dxhall on March 22, 2020, 08:58:24 AM

I posted this on the Britbike forum, but there wasn’t much response.  Anyone here have any ideas?

I am building a cafe bike with a Benelli Mojave frame and a BSA A65 motor. I would like to use a set of forks from a ‘71 BSA.

The steering tube in the stock BSA lower triple clamp is too short for the Benelli steering head. Since I have a lathe and a milling machine, making a longer tube is not a problem. Unfortunately, I do not see how to remove the old tube, other than by cutting it off at the base and drilling the stub.

Is there an easy way to remove the steering tube from the lower triple clamp? I don’t want to butcher the thing unless I have to.

I'm not a BSA guy. I have a Norton and find the folks at accessnorton.com knowledgeable and helpful.

Maybe bake in the oven and press it apart? Just a guess.

Best of luck

It is most likely sweated in.  DonG

Post a picture, they varied in construction.
Some (alloy) had a lower nut, others a shoulder or welded, either way the design stops the two parting company via positive stop.

How about cutting the tube, then turning an extension with a shoulder that slips into it. Sweat it in, pin it, plug weld???  That way you don't have to disturb whatever bond the cast bit and the original tube have. Does that make any sense?
