Y Drive Belt
There are four Y drive belts used on the EMT 10/4T. One each is associated with the
Y carriage assemblies in the channels at either end of the peripheral. Two are
associated with the middle Y carriage assembly in the middle channel. Figure 2-9
shows an illustration of the middle channel parts.
Replacement
NOTE: After performing this procedure, a specific Melco force gauge (p/n
995586-01) is required for proper belt adjustment.
To replace a Y drive belt, refer to the following procedure:
Caution! Never disassemble more than one Y carriage area at the
same time. By doing so, the parallelism of the X beam with the Y
carriages is threatened and may require service by a Melco trained
technician.
1. Turn OFF the peripheral and unplug the power cord from the source.
2. Remove the channel cover associated with the Y drive belt being replaced.
3. Refer to the Caution statement at the beginning of this procedure and be certain
the Y drive belts in the other Y carriages are secure and with some amount of
tension.
