AMAYA XTS/XT X-Cable Tension

The following instructions will guide you through checking and, if necessary, adjusting the X-Cable tension on your AMAYA XT or BRAVO machine.  The X-Cable Tension Gauge (Melco PN 33909), shown in picture 1 below, is used to indicate the permissible range for proper X-Cable tension.

Determining if an X-Cable is Set to Required Specifications

1. Remove the right transparent Side Cover shown in picture 2 below. Using a 4mm bent Allen wrench, remove the three indicated screws and carefully remove the Side Cover.

2. Center the Y Belt Clamp between the two black indicator marks on the Y Belt, as shown in picture 3 below, by moving the X-Beam forward or back.

3. Move the X-Carriage left or right until the two screws indicated in picture 4 below are centered to the Lower Arm.

4. Position the X-Cable Tension Gauge on the X-Cable as shown in picture 5 below. Center the Gauge between the indicated Pulley and the Upper Arm.

5. A properly adjusted X-Cable will fall within the cutout area shown in picture 6 below.  If the X cable falls within the cutout area, remove the fixture and re-install the Side Cover.

6. An improperly adjusted X-Cable will be positioned outside, either above (tension too low) or below (tension too high), the cutout area as shown in pictures 7 and 8 below. In this case the tension of the X-Cable requires adjustment. Follow steps 1-5 in section B below to properly adjust the tension of the X-Cable.

Adjusting an X-Cable that is Tensioned Outside the Required Specifications

1. Locate the M4 Nut and the X-Cable Stud at the end of the X-Cable where it mounts to the front of the Upper Arm as shown in picture 9 below.

2. Using a small Crescent wrench grip the M4 Nut (shown in picture 9 above) and with a pair of pliers grip the X-Cable Stud at the end of the X-Cable as shown in picture 10 below.

• To increase the X-Cable tension (X-Cable was located above the cut out area as shown in picture 7), rotate the pliers clockwise while holding the M4 Nut with the Crescent Wrench.
• To lower the X-Cable tension (X-Cable was located below the cut out area as shown in picture 8), rotate the pliers counterclockwise while holding the M4 Nut with the Crescent Wrench.

3. Remove the wrench and pliers and move the X-Beam full travel to the front and back and the X-Carriage full travel left and right a few times to ensure proper settling of the X-Cable tension.

4. Repeat steps 2 – 5 in section A and verify that the X-Cable is now adjusted to required specifications. If the X-Cable tension is adjusted properly, remove the fixture and re-install the Side Cover.  If the X-Cable tension is still not adjusted properly, repeat steps 1-4 in section B until the X-Cable tension is adjusted correctly.

Adjusting the Tension on a Replacement X-Cable

1. If a new X-Cable had to be installed on the machine, the initial X-Cable tension adjustment should align the X-Cable with the small cutout area on the X-Cable Tension Gauge as shown in picture 11 below.

2. Follow steps 1-4 in section A to properly position the X-Cable Tension Gauge on the X-Cable.

3. Follow steps 1-3 in section B to adjust the tension in the X-Cable until the X-Cable aligns with the small cut out in the X-Cable Tension Gauge as shown in picture 12 below.

4. After initial adjustment of the tension in the new X-Cable the X-Cable will stretch (= X-Cable tension will decrease) to a point where the X-Cable will fall within the required operating range as shown in picture 6.
