To remove the barrel assembly for cleaning or replacement, the process is straightforward. Simply remove the sensor, heater band, front bracket, and then unscrew the bolts from the rear bracket. Finally, unscrew the grub screw that connects the coupler and the screw to detach the barrel assembly. The rear assembly is equipped with a deep groove thrust bearing to counteract any backward pressure from the screw, ensuring smooth operation during extrusion.
