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.

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 four sections. 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.

Bolt Locations

Step 10

This step will cover the mounting of the Ratchet & Pawl.

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.

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.

Step 12

Apply Lucas Red "N" Tacky grease to all gears after final assembly to ensure smooth operation and reduce wear during use. Once greased, rotate and spin the wheel to distribute the grease evenly before powering up.

After running gearbox for 15-30 minutes, reapply a light amount of grease. Reapply as needed.

Assembly instructions are interchangeable between all configurations of the GreyT Telescope Gearbox. For the purposes of this User Guide, the 2” Base Gearbox is used as an example.

Step 1

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.

Step 2

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 with the Ratchet.

The hole marked in green in the image below must be tapped to 5/16-18.

Step 3

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 with the Ratchet.

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.

Step 4

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.

Step 5

The Kraken X60 Motor is installed using two #10-32 x 1/2”L bolts.
