Aligning the wheels......

Now I know there is a thread on this site about wheel alignment and its affect on the belt so my attention was drawn to the BSA A10 forum where there has been a discussion going on about the best ways to align wheels. One chap pointed out a method which I have just tried on my new Thunderbird. He has posted up the following site and then you have to download a PDF file, which was intended for the Harley boys but, of course, it works for us as well. Take a look..

http://www.motorcyclemetal.com/Download18.html

Download the pdf file "Wheel alignment made easy". by clicking on the small icon in the bottom LH corner.
I have to admit that I have previously used the length of string down one side of my bikes technique and this was something completely different, to me at least.
Apologies if it has been posted up previously.

Hi Alan, I read that procedure with a lot of interest, as I have always used the string line method over the years...... But it is almost impossible with the T'bird..... mainly due to its wide rear tyre, and also the exhausts, sidestand and footboards....

So I have been looking for an alternative, and was working on the straightedges possibility, but, the logistics are just a bit to far out there.... or better word.... too difficult.....

But reading this alternative, and I'd never heard of this method before, I still seem to think that it may be only suited to bikes of similar front and rear tyre width... I mean with the width of the rear TB, I think it would still be able to touch in 4 spots even if tiwas way out to start with..... Or have I missed something...AGAIN

Anyone can explain it better....???

NOTE... This is very relevant as the preceding thread about the belt/pulley/cush drive noise, has a need for "true" alignment set up...

Cheers JD

I've read other string methods and there are several variations. Heres the way i intend to try to do it next time i attempt an alignment.

Put a string around the back of the rear wheel. probably wrap it thru the wheel a few times to hold it in place well. Take the string on each side of the tire and tie the end to a heavy weight like a cinderblock. Each side the string should be long enough to pass the front wheel completely. Now bring the weights past the front wheel and move them into position where the string just touches the rear tire at the front of it. So the string is coming off the rear of the rear tire then touching the same part of the tire at the front of it with the weight holding the string in place beyond the front tire. Now turn the front wheel till the string is the exact same distance to the front edge of the front tire and the rear edge of it. The measure the opposite side and if they fornt and back edges are the same measurement it's aligned. If not then you know what to do.

That to me seems like the easiest way to do it and the simplest to grasp. Tho my description may be hard to follow i tried to make it as clear as i could.

Hi Dazco,.. thats pretty much how I have always done my bikes, but these always had similar sized front and rear tyres, so the gap at the front was easy to judge....

However, the difference in size of the TB makes it a whole different thing.... I might try the weight system too...

But I just had a thought.... I wonder if there is some way of packing out the string, evenly, to the same width as the rear tyre, at the front edge of the front wheel and measuring off the back edge.... although, I think its still an issue with the exhausts, etc.....?????

I suppose you could by getting something like wood planks and bungee cording them to the front tire. But it may be hard to find just the right thickness. of course it wouldn't have to be exact. They probably be best when they make the front a tad wider than the rear. I don't see the problem tho with the rear being much wider. The measurements on the front tire should be just as easy to do if it's 2 or 3 inches vs say a inch.

As for exhausts or anything else in the way, i haven't looked at it and sized that consideration up yet, but worse comes to worse i'll remove them. I also think once i have the wheel dead on i am going to make my own markings on the swingarm so that i CAN use them since the stock marks are off. That way i'll only have to do the string alignment once.
