What Belt Size Does Your 5a Have?

[Lin]

Back to belts

Since the belt on my 5a was a C106, that's what I ordered.  When it came today, my thought was why should I run the old belt and store the new one as a spare.  I figured it would be best the other way around.  So I went out to make quick work of this belt change.  But surprise, surprise, that was not to be.  It took me several hours.  I had to loosen everything I could find to be able to get the drive to wiggle enough for me to struggle rolling the old belt off and the new one on with serious coaxing with a screwdriver.  I am therefore wondering if I really should have had a longer belt.

I know that the belt tension system on these buses are not likely to be original, so it is likely that there are many variations in our equipment. But I am curious to see what size others are using.  Also, if you think there is some secret bolt that I may have missed that could have made the job reasonable.
