Vibra-TITE VC-3 Threadmate () is recommended on all bolts that thread into a tapped hole.

Step 5

Press the 88T Rotation Gear in by hand. If necessary, use a dead blow hammer to lightly tap it in.

The Bevel Gear Shaft must be installed through the bottom side of the 12mm bearing. Use the 3/8" snap ring to retain the gear and shaft.

The 16t Second Stage Gear for the X2 Ratio Set is on a 18t Center Distance.

The 14t Second Stage Gear for the X4 Ratio Set is on a 16t Center Distance.

Step 6

The 1/4” ID x 5/8” OD bearing can be pressed into the Wheel Fork by hand. Once the bearing is in place, use the #10-32 x 1- 1/2”L bolts to install both forks into the module.

Step 7a

Step 7b

Use the 1/4"-20 x 1/2"L bolt to attach the Encoder Shaft. This may be a tight fit so use the bolt to fully seat the Encoder shaft.

Then slide the Cartridge and Column Gear Spacer onto the Encoder Shaft.

Step 8

Slide the Rotation Gear and Rotation Shaft into position.

Install the two 15mm ID x 24mm OD bearings into the desired Column Gear. Refer to the page for the correct Column Gear for your selected ratio.

Vibra-TITE VC-3 Threadmate () should be used for the 1/4"-20 bolt shown below.

The Gear Spacer can be swapped with a Snap Ring (McMaster P/N ) if preferred.
