5 Installing the ST4000+
Drilling the spoke clamp holes
1. Remove the wheel drive front cover:
• the front cover is held onto the wheel drive by three ‘push-fit’
posts which sit in three sockets on the drive ring
• to remove the cover, hold the motor in one hand and use your
other hand to pull the cover up and away from the drive unit
(as shown below)
2. Identify the appropriate spoke clamp holes for your wheel. With
the arrow at the top, refer to the following diagrams:
• the holes are numbered inside the cover (e.g. if you have a 5
spoke wheel, you need to drill the 4 locations marked with ‘
5’)
• mark the appropriate spoke clamp holes and check them by
holding the cover against your wheel
