torque both set screws to 3in*lbs
Straighten the Y-Idler Belt [AS-PR0124] into a loop with no twists, with the machined idler in your right hand, ensure the M5 screw protruding from the machined idler is facing downward. Loop the end in your left hand around the motor pulley.
See example photo.
Place one 625-2RS Bearing [HD-MS0411] into the Y-Motor Mount
Place the motor shaft into the bearing then use four M3x10 [HD-BT0148] with washers [HD-WA0038] to secure the motor to the Y-motor mount. Torque fasteners to 5in*lbs

Place fastener through the terminal ring of [EL-HR0171]
Place the fastener back in the hole from which it was removed and tighten securely.
Finish tightening the M3x10 screws securing the bearing holders to the bed plate, starting with all inner screws then ending with all outer screws.
Be sure the belt is centered and resting against outer side of the Y-belt mount. the Y-belt mount should be centered between the Y-motor & Idler ends.
