Bronze Wheels Support Replacement

The function of the bronze wheels is to guide and support the movement of the gripper guide when the actuator gripper assembly is activated.

To implement this procedure first you need to follow the procedure of Lower or upper Gripper Actuators Assembly Replacement.

The two bronze gripper guide wheels lower and upper may become worn out due to constant friction.
