To change the blocks, just remove the
two screws, insert the new block(s) and
re-install the screws. Below are some
tips.
Only change one side at a time.
The long screw always goes on
the base side of the wheel.
The right-side top block has a
notch for the sensor wire.
You can use different sized for
the Pull Ring and the Push Ring.
If you need less than 30mm of
travel then please contact me.
