Lint Wiper
Located on the underneath side of the X drive belt tensioner block is a piece of
Velcro attached with adhesive. This item is used to keep the top surface of the X
carriage "brushed" clean and smooth for accurate reading by the X home sensor in
that area of the carriage. In the unlikely event this needs to be replaced, it must be
formed with a ripple in it to reach the X carriage surface but with some yielding of
position. To form this ripple, simply form the middle section of the piece of Velcro
around a 2mm (or equivalent) hex wrench as you attach it to the tensioner block.
When the Velcro is securely attached, twist the wrench out from between it and the
block. A rippled portion of the Velcro piece remains.
X Motor and Belt
The X motor is attached to the middle of the back side of the X beam. It has a
pulley driven belt coupled to a second belt (the X drive belt) to drive the X carriage.
Refer to the following procedure to replace the X motor and belt; and adjust the
belt tension.
Motor Replacement
NOTE: This procedure requires a specific Melco force gauge (p/n 995586-01) for
proper belt adjustment after replacing the motor.
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 five screws on the top, then
lifting the cover off the entire length of the X beam.
3. Loosen the two return pulley block mounting screws shown in Figure 2-6, then
loosen the drive belt tensioning screw to loosen the drive belt.
4. Rotate the X drive belt off the X motor pulley.
5. Refer to Figure 2-8 and remove the screws holding the X beam PCB cover.
6. Move the cover away from the motor far enough to access the X home sensor
harness and the X motor and encoder harnesses on the X beam PCB.
7. Press the tab in the middle of the connector to disconnect the X motor encoder
harness from the X beam PCB PCB.
8. Press the tab in the middle of the connector and disconnect the X motor drive
harness from the X beam PCB PCB.
9. Remove the 4 screws and associated hardware holding the X motor in place and
remove the motor (see Figure 2-8).
