More Tools
This is my second column concerning simple tools you
can make to simplify checking and adjusting race sag on the rear shock. In
my last column I described in detail the procedure used to create a sag
stick, which, once completed, is extremely useful for checking and setting
race sag. Today I will describe two more tools which are mainly used for
adjusting race sag.
 The
first of these two tools is a punch you can use to loosen the preload
adjuster rings. It can also be used to turn the adjuster rings.
You will need a piece of 5/16 inch round or square steel rod approximately
12 inches long. On one end, cut or grind two flats at 45 degree angles
to the length of the rod such that they form a 90 degree point in the center
of the end of the rod. This end will fit into the notches in the
adjuster rings such that when the rod is struck with a hammer it will turn
the ring without digging into the notches. It works much better than a
screwdriver or a chisel.
The final tool is made from a screwdriver. It
will serve as a pry bar to turn the adjuster rings, but it is NOT to
be hit or struck. You need a flat blade screwdriver with a 1/4
to 5/16 inch rod shaft approximately 8 to 10 inches long. Clamp
the screwdriver end in a vise, flat sides against the jaws, at approximately
1 to 1 ½ inches from the end. Put a slight bend in the shaft. You will
use this as a pry bar between the reservoir and/or frame tube and the end in
the notches of the adjuster rings. Then you can just pry the adjuster
rings around to adjust preload. You may have to play with the length
and amount of bend you need, depending upon your make of bike. Each
make, model, and year has different space requirements.
Mark these three tools and keep them together.
The next time your weight changes (maybe every two weeks?) you will have the
right tools to both check and adjust race sag.
For a detailed description of sag settings, refer to my
second column Race Sag and Spring Rates.
Remember to always use proper
safety precautions and equipment including eye protection when drilling or
cutting metal. |
