Rex
Just read your post, no, perhaps I did'nt explain in sufficient detail.
I have the hub, cut out of the rim, on the bench. It has a hollow sleeve in the bearings which the spindle goes thro. I have taken the b/plate retaining nut off, very fine thread, very thin sleeve, and that is as far as I have got. B/plate will not lift off.
 Need it off to take out the sections of spokes left after cutting them. B/plate rim covers them.
As I said in the the initial post, what throws me is it's an A65 hub, or is it a Triumph, and in Dragonfly's exploded views of BSA, they were fitted 68-70 and with a solid, captive spindle, held in the forks by f/clamps. This one was in the forks via, I think, a 7" spindle going thro. the sleeve, and as you say, screwed into the fork leg.
Did Triumph fit that hub, but with a sleeve for the spindle to go thro.
Need to go and do battle again.
Ken.

Hi    mini-me,
My first thought after first attempt. Shoes stopping removal, used to get that sometimes with car drums and the self-adjusters moving the shoes out into the undercut drum.
No, the shoes seem OK.  B/plate rotates OK. I'll have another go with the 2 leading shoe b/levers tiebar removed,  failing that, I'll make a bearing retainer tool and try something from the other side. Need to make one anyway for the 8" s/s  hub to install a bearing spacer to replace this one.
I was thinking last night, do I actually have a Triumph hub, not a BSA one.

I recently removed an early A7 front wheel (or tried to!) and the sod was much the same as you describe. The removable spindle would unscrew from the opposing fork leg, but not pull back out.
In the end I dropped the stanchions down and out of the yokes which left them both "independent" and the brake one lifted off with no problems. The wheel spindle was clearly partially seized in the central spacer portion of the hub, although a dead blow hammer eventually persuaded the whole assembly to come out c/w the near-side bearing.
Plusgas soon had the assembly back to it's component parts.

Lots of mix an match possibilities with BSA.

If you have the nut off, then only the linings can be preventing it being removed.
Can you spin the plate freely? if not , try moving the brake lever which will release the grip of the linings.

Or possibly you could remove all the bearing retainers from the opposite side and knock the shaft through backwards.
Or of course it could be a right lash up and god knows what you have.

Too many bodgers have had these bikes through their hands over the years which is why 'as found'machines fetch a premium.

photos are a help everytime.

Hi All,
I apologise for these posts. I'm not a BSA man, so I'm in the dark just now.
The bike came fitted with an A65 f/hub, and as I said previously, a spindle which have I discovered on doing a bit of reading, is a 7" brake hub spindle. The B forks l/h thread screw in one.
I tried to take off the A65 brake plate and could not. Backed off the retaining nut and gave it a few bumps with a plastic mallet. Nothing. Heated the plate, WD40, and bumped again . Nothing moved. I could waggle the b/plate a bit on the sleeve.
Came in and looked at Draganfly's exploded views. Then I noticed these hubs were only used for 3 years, and that they have solid "retained in hub" spindles.
So, has this hub had a hollow sleeve to accept the old screw-in spindle made and fitted, to fit B model forks or is there a BSA fitted with what I describe. AND, how do I get the damned b/plate off without damage.
Regards,   Ken

Rattle, I think there's an organisation called The British Two Stroke Club; or something similar. I've seen them referred to in connection with dating.
HTH, Dave.

Sorry Rattlehead, sounds like you live in the UK. I live in Australia. We have our own crazy rules and regulations but they're not the same as yours. Someone on this forum will know what hoops you have to jump through.
Best of luck.

That engine is a replacement. The engine number prefix identifies it as an engine first fitted to a 1950 James, not an Excelsior. According to my local police records the appropriate engine number prefix for your model Excelsior was 905/***. This is not surprising as for many years it was far cheaper to buy a used Villiers engine from a wreckers than to spend money on rebuilding a worn out one to new. Plus of course if you did lash out on a reconditioned exchange unit no one cared about the original engine numbers anyway. This was a daily rider working bike not anything fancy.

As to the gear ratios, Villiers identified the change over to ratios more usable on the road by stamping a 'D' suffix after the engine number. This also identifies updates to the crankcase compression seals. You can see from your engine number that both the original engine and the one you have now came from the factory with the wide ratio box but who knows what has been done in the last 60 years. If you want to know all the technical ins and outs buy yourself a third or fourth edition of "The Villiers Engine" by B E Browning and published by Pearsons.

Welcome to the wonderful world of Villiers.
Cheers,
Hi 33d6, I need a dating certificate for this bike, any ideas?
Cheers.
