Hi Jeff,
Yes, this pin is very important as it prevents the sleeve from spinning - a
must if
you want the fork pins to last a long time. Your best bet is to drill a 3/32"
hole at
about 90 degrees to the roll pin's original location and insert a 3/32" dowel
pin
(which is solid steel) instead of the 1/16" roll pin (which is coiled spring
steel).
The pin is trapped in the hole by the throwout bearing, so there is no need to
have a
super tight fit here. Just be sure you don't drill the new hole all the way
through
to the back side of the sleeve.
If you are having trouble with the roll pins breaking, you may be stressing the
throwout bearing when you are installing it on the sleeve. Try this: balance
the
throwout bearing atop a 75 watt lightbulb held in a vice or similar. The
transmission
side of the bearing should be in contact with the bulb. Keep the sleeve in a
cool,
dry place (below 70 degrees). Wait 20 minutes. Wear a leather shop glove and
quickly
remove the throwout bearing and place it atop the sleeve. Due to the heat
expansion
of the throwout it will drop straight down in place with no effort. Allow it
to cool
naturally and the two will be shrunk together. The heat from the lightbulb is
no more
than the bearing will see in normal use inside the bell housing, and there is no
chance of damaging the individual balls or races in the bearing by pressing it
even
with the special tools available.
