Assembly instructions are interchangeable between all configurations of the GreyT Telescope Flipped Gearbox. For the purposes of this User Guide, the 2” Base Gearbox is used as an example.
Blue Loctite (McMaster P/N 1004A12) is recommended on all bolts that thread into a tapped hole.

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.
If you do not plan on assembling the Gearbox with either the optional Friction Brake or Ratchet & Pawl, you may omit the parts boxed in blue in the image down below.
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” Base 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.
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.
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.
This step will cover the mounting of either the Friction Brake or the Ratchet & Pawl.
This step can be skipped if you plan on using the Telescope without the Ratchet & Pawl or WCP 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.
To mount the Ratchet & Pawl, first drill and tap to 5/16-18 the hole the Pawl mounts to. Then mount the Ratchet & Pawl using the parts shown in the image down below. Finally, drill out the mounting hole at the end of the piston with a #18 drill bit and mount the piston once everything else is in place.
Piston and #8-32 x 1”L Bolt are not sold by WCP.
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.
Blue Loctite () is recommended on all bolts that thread into a tapped hole.
The Drum must be cut to the correct length for the Gearbox Configuration you are assembling. The table down below shows the correct lengths for each base tube size.
All #10-32 bolts will thread into the 7/8” OD Roller Hubs after they have been pressed into the Drum. The Roller Hubs should be a press fit and may be pressed in with an arbor press.
When assembling the drum, it is critical that the hexes for the roller hubs are lined up. In order to do this it is recommended to press one Hub in, and then line up the second Hub with the first Hub using any long piece of 1/2” hex.
| Base Tube Size | Drum Length |

These bearings will be a light press fit and may be pressed in by hand or with an arbor press. The image below shows the side the bearings must be installed from for all configurations of the Telescope Gearbox.
If you plan on assembling the Gearbox with the Ratchet & Pawl, the hole marked in green in the image below must be tapped to 5/16-18. Otherwise, that hole can be left alone.
If you do not plan on assembling the Gearbox with either the Ratchet & Pawl or WCP Friction Brake, you may omit the 1/2” Hex ID x 1-1/8” OD Flanged Bearing boxed in blue in the image down below.
The 1/2” ID x 1-1/8” OD Flanged Bearing will be a light press fit and may be pressed in by hand or with an arbor press. The image below shows the side the bearing must be installed from for all configurations of the Telescope Gearbox.
The Nutstrips used to mount the GreyT Telescope must be cut to 1-1/2” long and assembled in the orientation shown in the image below.
For the assembly of the Gearbox in the Flipped configuration, you may omit the Nutstrips and associated Bolts from this step.
The 1/2” Rounded Hex ID x 1-1/8” OD Flanged Bearing will be a light press fit and may be pressed in by hand or with an arbor press. The image below shows the side the bearing must be installed from for all configurations of the Telescope Gearbox.
The Nutstrips used to mount the GreyT Telescope must be cut to 1-1/2” long and assembled in the orientation shown in the image below.
Just like in the previous step, the Nutstrips in this step are completely optional. For the assembly of the Gearbox in the Flipped configuration, you may omit the Nutstrips and associated Bolts from this step.
The Kraken X60 Motor is installed using two #10-32 x 1/2”L bolts.
