X Beam Assembly
The X beam assembly consists of the X carriage, X motor and belt, X drive belt, and
various other mechanical components that make up the device that holds the hoop
during the embroidery process. The X beam is attached to the Y drive system by
connecting to the Y drive rails at the middle and either end of the beam.
This assembly and its installation to the peripheral requires specific factory tooling
and training to maintain the assembly’s parallelism with the rest of the peripheral.
Portions of the carriage assembly, however, may be disassembled to replace various
parts without sacrificing the overall orthogonal integrity. The following procedures
are for replacing such parts.
X Drive Belt Replacement
NOTE: This procedure requires a specific Melco force gauge (p/n 995586-01), for
proper adjustment.
Refer to the following procedure to replace the X drive belt:
1. Turn OFF the power switch to the EMT 10/4T and remove the power cord from
the power source electrical outlet and the machine.
2. Remove the X beam cover by first removing the screws on the top, then lifting
the cover off the entire length of the X beam.
3. Refer to Figure 2-6 and loosen the drive belt tensioning screw, then the two
return pulley block mounting screws to loosen the drive belt.
4. The existing X drive belt is clamped and held to the X carriage plate by two flat
head socket screws, a clamp, and a spacer. The screws go through holes in the
belt as well. Remove the two socket screws and associated clamp and spacer to
free the belt at this area (see Figure 2-6).
5. Slide the old belt out of the two pulleys at either end and position the new belt
into place where the old one was.
6. Bring the ends of the new belt together above the two holes in the X carriage
plate.
7. Position the X belt clamp above, and the spacer below the belt ends,
sandwiching the belt between them.
8. Insert the two socket screws through the clamp, the holes in the belt ends, the
spacer, and into the holes in the X carriage plate. Tighten the screws snug.
9. Refer to the following belt tensioning procedure for adjusting the X drive belt
tension.
