Step 6-11

Blue Loctite (McMaster P/N 1004A12) is recommended on all bolts that thread into a tapped hole.

Step 6

Slide on all components in the order shown in the image below. If you plan on using a CTRE Mag Encoder on the Output Shaft, you must drill out the shaft and press in the 1/4” OD x 1/2” L Magnet.

Step 7

Bolt the two halves of the Gearbox together using the #10-32 x 1-3/4”L bolts. The image down below shows the bolt locations marked out in green.

If you are assembling the 1-1/2” Gearbox, you can omit the 1/8”L spacers. For those configurations of the Telescope, those bolts will act as pins that hold the 1-1/2” Base Tube in place.

Step 8

Slide the assembled Drum from Step 1 onto the output shaft. You may have to loosen the #10-32 x 3/8”L bolt in order to do this. Once the Drum is in place, check that the flange does not rub against the Gearbox Plate when the output shaft is spun by hand.

Step 9

Bolt the two halves of the gearbox together. The bolt locations for the different Gearbox configurations are shown on the following section. When the Gearbox is fully assembled, make sure the Drum Flanges do not rub against the Gearbox Plates when the Output Shaft is spun by hand.

Unless otherwise specified, the bolt locations are the same across both the Non-Flipped and Flipped configurations.

Bolt Locations

1-1/2” Base Gearbox

1-1/2” Base Gearbox

The images shown below mark out the bolt locations in green, blue, and orange. These configurations of the Gearbox both use #10-32 x 2”L bolts and 1-1/2”L spacers.

The 1-1/2” Base Gearbox does not require the 1/8”L spacers installed in Step 7.

2" Base Gearbox

2” Base Gearbox

The images shown below mark out the bolt locations in green, blue, and orange. These configurations of the Gearbox both use #10-32 x 2-1/2”L bolts and 2”L spacers.

The 2” Base Gearbox does require the 1/8”L spacers installed in Step 7.

2-1/2" Base Gearbox

2-1/2” Base Gearbox

The images shown below mark out the bolt locations in green, blue, and orange. These configurations of the Gearbox both use #10-32 x 3”L bolts and 2-1/2”L spacers.

The 2-1/2” Base Gearbox does require the 1/8”L spacers installed in Step 7.

3" Base Gearbox

3” Base Gearbox

The images shown below mark out the bolt locations in green, blue, and orange. These configurations of the Gearbox both use #10-32 x 3-1/2”L bolts and 3”L spacers.

The 3” Base Gearbox does require the 1/8”L spacers installed in Step 7.

Step 10

This step will cover the mounting of the Friction Brake.

To mount the Friction Brake, first bolt the Break Pad to the Outside Gearbox Plate, then mount the Piston Mount, and finally install the Piston with Cone.

Piston and #6-32 x 1-1/4”L Bolt are not sold by WCP.

Step 11

Install the 3D Printed Mag Encoder Mount using two #10-32 x 1/2”L bolts. To install the Mag Encoder, remove the board from the case and fit it into the cutout on the 3D Printed Mag Encoder Mount. Use the mounting bolts from the Mag Encoder to attach the sensor. The CANcoder can be used as a drop in replacement.
