These silver coloured pins have a barrel diameter of 1.75mm and
were used throughout the 1990s and beyond. They are used to secure
the wires from the motor to the pick up braids on the guide assembly,
see the guide pictured above. This guide blade is sometimes referred
to as G30.
Caution:
Some of the earlier versions of the G30 guide (pictured above)
have suffered from material creep. This is where the plastic material
has stretched over time. This means that these 1.75mm diameter
pins will appear loose and in extreme circumstances come out under
race conditions. In this situation the guide can simply be replaced
with a new guide
assembly or the larger 1.95mm
diameter pins can be used.
Note:
Please note that the latest supply of these 1.75mm guide pins
are natural brass in colour and not the traditional bright nickel
plate as indicated above. Their function and performance is not
affected with this change.
