Integrated Carbon Mast Installation:

Step 1 – Prepare the Motor
Apply a thin layer of Foil Drive Grease around the outside of the plug. Do not grease the inside.

Step 2 – Check the Red O-Ring
Verify that the red O-ring is properly installed on the puck to ensure a waterproof seal.

Step 3 – Remove the M5 Split Bolt
Remove the (1x) M5 52mm Titanium CSK Screw and (1x) M5 20mm Titanium Barrel Nut

Step 4 – Gently Remove the Puck
Carefully pull the puck out of the mast. Do not yank on the cables; keep it gentle.

Step 5 – Bolt Puck to Motor
Use the (4x) M4 10mm 316 Dome Head Screws to attach the puck securely to the motor.

Step 6 – Insert Motor + Puck into Mast
Slide the puck and motor assembly back into the mast. Double-check cable positioning as you go.

Secure the motor assembly in the mast by tightening the M5 52mm Ti CSK Screw and M5 20mm Ti Barrel Nut.

Step 8 – Fit Cable to Electronics Box
Blue O-Ring MUST be clean, well lubricated and in place. Use Foil Drive Grease to lubricate O-Ring if needed, then plug in the cable and install the bolts.

Step 9 – Secure Mast to Electronics Box
Using the (2x) M8 16mm 316 Ti Coating CSK Screw (T40 torx head), secure the mast to the electronics box.
