chain adjusting problem - advice?
Posted: Mon Mar 26, 2001 3:51 pm
About 2000 miles ago, after adjusting the chain on my A-12, I noticed that
the rear brake disc was heating up. I had been very careful to align the
marks on the outer chain adjuster with the marks on the swingarm, measuring
them with a steel tape to the nearest 1/32".
After searching the archives, I went through the drill for sticky brake pad
pins, but that didn't help. The rear brake didn't seem to drag with the rear
wheel off the ground, but it must have been dragging to some extent to
generate the heat. The problem resolved in about 200 miles, presumably from
wearing in the pads to the new alignment.
Now, upon adjusting the chain again, I discovered that the holes in the outer
chain adjuster (the indexing bracket) are larger than the axle, and allow it
to slide back and forth, introducing 3-4/32" play, making it impossible to
adjust the two sides accurately (when only 1 or 2 facets of the adjusting nut
make the difference between "too tight" and "loose enough."
Has anyone else run across this problem? How do you accurately maintain axle
(wheel and brake disc) alignment while tensioning the chain? Are all the
outer chain adjusters made this way, or did mine wear out larger holes for
some reason?
Opinions and advice are welcome.
