Chapter 5: Installing the ST4000+ 655 Installing the ST4000+Securing the wheel drive to the wheel1. Remove the wheel from the pedestal and place it on top of thedrive unit, with the front of the wheel and drive both facing up.2. Using the wheel drive template at the end of this book, select thecorrect set of spoke clamp inserts for your wheel:• measure the spoke diameter at a distance of about 135 mm(5.3 in) from the center of the wheel• select the appropriate set of inserts: the wheel drive is suppliedwith 2 sets of 3 inserts suitable for 12 mm (1/2 in) and 16 mm(5/8 in) diameter spokes – each insert is marked with its size3. Fit the first spoke clamp:• lubricate the spoke with washing-up liquid – so you can slidethe spoke clamp along the spoke to adjust its position• place the insert on the spoke about 135 mm (5.3 in) from thewheel center – this distance is not critical as the wheel drivewill self-center as you fit all 3 spoke clamps• place the spoke clamp onto the insert, making sure that youhave correctly located the clamp insert in the clamp• locate 2 of the clamp screws (M5 x 16 mm allen-head screws)• lightly tighten the screws using the 3 mm allen key (supplied)4. Repeat step 3 to fit the other 2 spoke clamps. As you fit each one,adjust the position of the wheel relative to the wheel drive so theholes in the clamp line up with the holes in the cover. As you dothis, the wheel drive will self-center on the wheel.5. After fitting all 3 spoke clamps, fully tighten the screws.D5406-1135 mm (5.3 in)81131_8.book Page 65 Thursday, October 7, 2004 11:03 AM
