Before beginning this step, note the tension on the belt. During reassembly, you'll need to tighten the belt to the same tension.

Use a Phillips screwdriver to remove the 18.5 mm‑long tensioning screw from the bracket towards the back of the left side of the Cricut

The nut may be lightly adhered to the bracket. Use a wrench to loosen the nut so it comes off with the screw.

During reassembly:

Screw the nut away from the head of the screw by a few full turns.

Screw the screw into the hole in the bracket until the nut makes contact with the bracket.

Use a 6 mm wrench to hold the nut and screw in the screw until the belt reaches the correct tension.
