This procedure steps you through the installation and alignment of the ASI’s IX71 Z-axis motor drive onto the Olympus IX71 microscope.
NOTE: On January 2007 Olympus changed the size of the threaded end of their fine focus shaft from 3 mm to 4 mm. Microscopes with serial numbers '7Axxxxxx' and newer, and all 8-digit versions, identify the 4 mm version. The threaded shaft diameter can also be directly measured after the left-hand fine-focus knob has been removed. This installation manual applies to both versions.
The procedure has three parts:
Note: the terms ‘left’ and ‘right’ refer to the sides of the microscope as viewed from the front of the microscope.
Slide flexible coupler over the threaded end of the left fine focus shaft while holding the right fine focus knob in place, and tighten clamp with a 2 mm or 5/64 inch Allen wrench. Ensure that it is pressed all the way against the brass part of the left microscope knob without pushing the right focus knob out on the other side. Check for any play in the focus shaft by pushing and pulling the focus knob as shown on the left – no movement should be evident.
Note: The flexible coupler clamp must be securely tightened or the drive may slip.
Note: there should be no point throughout the 360º rotation of the fine focus knob where an increase in drag is felt. If drag is felt, repeat the above steps.
This completes the procedure for installing the ASI Z-axis motor drive onto the Olympus IX71.
