Question to the folks that have a 1969 BSA unit twin. I have 2 1969 A65's, and according to the parts book, both years state that the swing arm should have the rubber o-ring and the end caps just like a Triumph 650 twin. My problem is, both of my A65's do not have that. I had to replace the bushings on one of the A65's and there is no way for them to fit. Is this a "classic" parts book error? This set up below appears to be only for 1969.

I have just the swing arm off a 1969 Thunderbolt, and it is just like a Triumph.

Interesting! My A65's are early and late. What is the frame letters of your A65 if you don't m,e asking? Betwwen the 2 I have, there is just no way for them to "squeeze" in.

Sorry, but I couldn't tell you; I sold the frame a while back, but kept the swing arm since it was Triumph style...

After 50 years of use , abuse, wear & accident repair what are the chances that your bike is as it left the factory ?
About the same as winning the lottery
Without a ticket.
Good chance you will find a different length bearing fitted because the localBSA shop was not there any more but NAPA had one that would go in the hole.

Good point. I tried to install the end caps and o-rings but they will not fit? That's where my question begins. Hmmm..

I have a complete 1969 A65 swingarm assembly with all of the parts and pieces. It does not have the O-ring seals or the seal housings. Actually this swingarm assembly looks identical to what I have on my 1970 Thunderbolt which also does not have the O-ring seals or seal housings. Maybe the O-ring seals and seal housings were used on very early 1969 models.

Possibly your bike used rubber sleeve dust excluders p/n 83-1318. Here is a picture below from a 1970 A65 parts book showing item number 21 as the part you could use.

I thought of that as well, but just confused because both are 1969 models. At this point it really does not matter, just thought it was odd. Thanks for your insight. So we have 3 swing arms that appear not to be "correct" for 1969...

Yes indeed. They may even be the same part.

i think the parts diagram with the plate and O ring is a draughtsmans fantasy, it would be interesting to know if any really came like this. The bike inner tube seal is much cheaper and simpler to fit.

Hi,

Mine has the '1970' style. Could well have been changed over the years as the frame and swing arm came in the same pile of parts but were separated. This one uses Triumph bushes and bobbins as I found out recently.

I in fact discovered all this because I bought the parts listed in the 69 book and it didn't fit together. I thought the o-ring and cover system would have been much better. The manky piece of bike tube doesn't last long. I think suppliers think that anything that looks right works, rather than necessarily being made of 'suitable' materials. Wonder if doubling it up would be better. Not easy job to change that $1 part when it buggers up. I'd prefer to pay more an get something that lasts. Sorry will stop ranting now.

The manky bits of bike inner tube have been on my 71 since i renewed them in 1982, how long should they last?

It's not the suppliers... its some of the manufactures producing the rubber components using inferior materials. No rant at all :bigt

My 69 Thunderbolt never had the O rings just the rubber wraps on the ends for dust covers.

Gavin,

That's because you they were made non-manky in 1982. Now made from rubbish.

CBS,
Yes my apologies. Retailers can only supply what they can buy from suppliers manufacturers.
