British Bikes / Re: A65 68-70 front hub spindle conundrum, 55 Goldie
« on: November 28, 2017, 09:08:23 PM »
After a bit of a hiatus, I thought I would put an end to speculation about this hub.
What I have is a A65 two-leading 68ish hub with a one-off sleeve, 20mm on the OD, Imp. bore, to fit the metric hub bearings.
The sleeve was bored to accept the A/B 7" hub spindle, thus fitting the said forks. Can't make up my mind, was the sleeve b/plate retainer nut thread cut before boring, sleeve wall about 45 thou thick, or was it cut after, with very fine cuts. I'd go for the former. Anyway, thats what it is.
Not being a BSA/Triumph person, I thought I had some sort of intermediate hub, with the slot to mate with the later fork leg, AND a boss with a stud to accept the earlier leg brake torque stay. And the bearing sleeve to convert, of course. On washing and a closer inspection, the boss had been grafted on, welded (in quotemarks) to built it up, drilled and tapped. I cut and ground it off, and talk about a wing and a prayer. No penetration, just hanging on and no more. Gas, I would think.
Incidentally, some Vincents, 1951 build, during the Korean war, my how the World turns, seem to have heard that name lately, did the same. Bearing shortages, metric bearings, metric to Imp. sleeve. That cost me a few hours one time. Ho Ho.
So puzzle solved.
Regards to all who commented,   Ken.

Hi All,
Well I've cracked the non-removal problem.
Had another look after tea, took off the brake arms just in case, took out a circlip on the other side of the hub. Then put a vise grip, a real US one, on the 10mm or so I could get at on the non-brake side with a fair grip. Put the grip in the vice to stop it turning, heated the b/plate again and poured some lt. oil around the sleeve.
Then I tried unscrewing it. After a couple of mis-starts it started to unscrew. Got if off, and after a bit of mucking about, spotted the problem. This sleeve is 50 thou wall thickness, OR actually 1.25 mm. Checked the thread pitch and dia. Its 1*20mm. The damned thing is metric. The 14mm nuts on the b/levers should have warned me, I just thought they were some mad size. Anyway, tube wall 1.25,  thread depth, a bit over .6, so wall in the threads area .7mm ish.
So when trying to take off the b/plate by hitting the tube nut with the mallet, it compressed and swaged the tube/sleeve in the b/plate because it was so thin. In my defense it was in this state before I started.
So,  I still don't know what the hub came off and I need a new tube/sleeve.  Or a solid spindle. It must be Triumph, maybe, perhaps.
Night all.

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.

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.

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

Hi all,
I wonder if anyone can help with the dimensions of the 8" single-sided hub spindle, and the between bearings in-hub spacer.
The spindle which came with the bike, which had a A65 hub fitted, I have discovered, is for a 7" hub.
I got out the 8" hub I bought a couple of years ago to check, had a look into the spindle annular space and, no spacer. It has had new bearing retainers fitted, so quite an oversight.
The later spindle, the popular one,  would be 9" long, with a minor dia. of 11/16", lh threaded section 9/16". The main section, the larger dia., is 7/8" but for what length.  The spacer, I have no idea of any of it just now.
Any help gratefully received.
Thanks,  Ken.

Hi Leon and all.
Thanks for all the comments.
I think we will just accept the situation and move on.
 BUT, these dished washers, self- alignment devices, load spreaders, are made for the job.
As Rex says, CWC should provide the goods, and as Iansoady commented, yes, I seem to remember falling into that one a time ago.

Regards to all.
Next up, my petrol tank.

Had a closer look at these bits today. The nipples to take the dished washers are .065 ish smaller in dia. than the standard nipple you would normally use. Same gauge of spoke. Standard, as I would call them, are .302  9/32"and the ones from this rim are .250. The head is also a smaller dia. 0400" to .439" and flat topped. Though with the washers fitted they are actually wider. .490. So I would surmise that the smaller dia. nipple in the 9/32"hole in the rim gives more misalignment leeway, if it is needed. They can waggle around a bit to change angle to be spot-on, but with the washer, there is the same, or more,seat area.
Anyway, enough. I'll wait for the new spokes/nipples coming and take it from there.
Thanks for the contributions.

Stainless, brushed, it is.
Question is, do I need them. I would also have to make them. I think not. I think there would be better load-spreading, full nipple base to rim, than having a narrow band with less area intersposed between. And without cadmium, or stainless, there would be corrosion.

Thanks, Cardan.
I surmised that it was for loadspreading, although given the width of them, I don't see it very being effective. The rim is dimpled. I have ordered spokes and nipples from Central Wheel Components here the UK. Told them what I have and left it to them. Have'nt done a wheel in donkeys. Three to do, this bike and an Arrow front.

Hi All, just joined the forum a couple of weeks ago.
I'm usually just a reader. To the matter in hand, I have had this Goldie for a fair number of years, in boxes.
Had the frame blasted and I then painted it. Then we moved house, had to build a garage, etc, renovate house, so it stayed in the boxes. Anyway, have now started on it.
I cut out a couple of spokes since I need to rebuild the wheels, it has the later conical ? hub laced in, A65 ? It was a bit of a cafe racer, and I am going back to the 8" hub. It has a Dunlop WM 1 alloy f/rim. Now, when I took out the bit of spoke and nipple, it had a cup washer between the rim and the underside of the nipple head. Very narrow, more like the outer periphery of a cup. I have never seen this, or heard of it before. Something to do with spoke movement, or corrosion.  Any thoughts.
