A7 Swing arm Bushes - fitting to Swing Arm

[gpo746]

Been onto the supplier (Southern Division) in Germany. I supplied him with the same photos I put on here and within 24hrs he got back to me after he measured the ones he had in stock  . The ones he had supplied me were from MCA and they all measured the same as mine. He reckons there are only TWO wholesale suppliers that sell these items - WASSELL and MCA , WASSELL have no stock and have not had any for some time . It would appear the ones we are seeing now are from MCA. They can be identified by the grainy OD and shiny zinc coating . (I believe the original BSA articles were smooth matt in apperance) .The vendor in Germany thanked me for raising the issue and offered me a 50% refund If I wanted to keep the bushes and turn them down. Given there is an apparent shortage of these items I decided that I would take a chance . The seller was true to his word and has issued me the 50% refund as promised.
To be fair - I can't fault him on service!

In the circumstances that’s  a fair result, a word of caution,  when I saw some blocs being machined down the machinest guy was complaining that they weren’t round, being made of cheap thin wall tube, which made the job take much longer, I’m  not 100 % sure how he got around the problem, but he was using a 4 jaw chuck and dial guage to set them in the lathe, from memory.

Agreed berger.  If I had the space, money and know-how I'd make as much as I could myself.  Unfortunately, I don't have any of these things so I'll have to take my chances and consult my engineer mate.  At the end of the day, the bikes are all about  riding so, whatever it takes, get the bloody beasts on the road!!

yes wortluck if my dad hadnt have been an engineer i would be on those foreign bikes, ime lucky now that older brother has a heated workshop fully stocked and knows his stuff, i will admit i spent too much time in the pub instead of standing over dads shoulder, but it still pisses me off when basically nothing is made correct, ps whenever i see a 4 jaw mentioned i know people know their stuff.

[Worty]

Too right.  I'm more of a rider than an engineer, and I'd rather be riding than cocking stuff up in my garage and wasting time not being on the road.  I'm pretty competent with a lot of stuff, but specialist/critical things I'd rather leave to those in the know.  Good example is my family estate in for a timing belt.  Could probably do it if I had the time and didn't need the car, but neither of those options are available to me so it's £370 at a local indy!
Just so you know, I'm not on the bike today

Looks like its in Microsoft Office..which I cannot open  !. Only found this out after an hour of faffing about with Adobe and cursing at the computer  ...wifey (10 years my junior) found this out fairly quickly.

I don't have MS Office installed on this PC. I have the Open Office Suite, (which is free) and that will open the document.

when i did my s/wing arm bushes i gave up and took 'em to our local RE dealer bikeshop, they have avery sturdy press ,I talking to the owner and we heard the loudest bang I've heard in a long time ,the owner went white rushed into the back expecting to see body parts instead the litlle apprentice came back in with a grin from ear to ear  ,he just said "that got it " turned out he'd had to wind it up to max and nothing moved ,he turned his back and everything let fly but it worked ,don't exactly look forward to have to renew 'em again

Blimey! ...it does sound like a daunting job . I will have a go and let you all know how it goes .

Thinking back to my first experience of fitting these bushes ,that would be 1968, I fitted the bushes to the swingarm of my A7SS using two blocks wood with a studded bar right through the swingarm ,large washers etc no problems , so the guy who questioned modern sizes/quality was completely correct .
