The procedure below outlines the steps necessary to install the ASI Microscope Focus Controller Drive onto the Olympus MVX 10 microscope.

To perform the following steps you will need the following tools:

Flat & Phillips screw drivers & a pair of Pliers 1.5mm, 2.5 mm, 3mm, 1/16 and 7/64 inch hex wrenches Small piece of Emory cloth The hex wrenches are provided by ASI.

The procedure has 6 parts:

1. Removing the Objectives, Trinocular head & Fluorescence illuminator to reduce weight when installing the drive assembly
2. Removing the left fine focus & the zoom knob
3. Installing the base plate & motor drive assembly
4. Aligning the motor drive assembly
5. Installing & aligning the Zoom belt drive
6. Installing the motor drive cover plate & fine focus knob
7. Connecting the cables to the controller

If necessary, please refer to the Olympus manuals for this microscope.

Figure 1 Remove the Objectives, Trinocular head & Fluorescence illuminator to reduce weight when installing the drive assembly. If necessary, please refer to the Olympus manuals for this microscope.

Remove the left fine focus knob from the microscope as follows:

Figure 2 remove the rubber boot off of the end of the left fine focus knob

Figure 2 remove the rubber boot off of the end of the left fine focus knob

Pry the rubber boot of the end of the left fine focus knob (ffk), on some scopes a screwdriver may be needed to pry the knob off as it may be glued on.

Figure 3 shows the location of the 3x 8 mm screw that must be removed / loosened to remove the ffk. Use the 2.5 mm Allen wrench to remove the screw while holding, or turning, the right fine focus knob.

Figure 4. The focus assembly will rise up when the ffk is removed.

Figure 5. Check and make certain that the two spring washers remained inside of the coarse focus knob as shown & are not stuck to the inside of the FFK. If they are stuck to the ffk remove them and place them inside of the coarse focus knob as shown.

Figure 5. Check and make certain that the two spring washers remained inside of the coarse focus knob as shown & are not stuck to the inside of the ffk. If they are stuck to the ffk remove them and place them inside of the coarse focus knob as shown.

Unscrew the screw that secures the ffk & remove the knob as shown in figure 5. The focus assembly will rise up when the ffk is removed as shown in figure 4. Insure that the two spring washers remained inside of the coarse focus knob as shown in figure 5. If they are stuck to the FFK remove them and place them inside of the coarse focus knob as shown. Store the ffk & 2.5 mm screw that retained it, as they are not needed with the ASI Z-drive.

Figure 6. Use a cross blade screwdriver to loosen the three Philip head screws and remove the coarse focus knob as shown.

Locate the brass clutch plate & Fine Focus Shaft Extender (FFSE) and install them as shown in the above photos a through d. Note that the clamp & clutch plate must compress the wave washers as shown in photo c. This is done by firmly pressing the clamp & clutch plate against them. You may have to open the clamp up a little bit with a flat blade screw drive as shown in photo d.

Locate the brass clutch plate & Fine Focus Shaft Extender (FFSE) and install them as shown in figure # 7, photos a through d. Note that the clamp & clutch plate must compress the wave washers as shown in figure # 7 photo c, and figure # 8 below. This is done by firmly pressing the clamp & clutch plate against them. Please note; you should insure that the right fine focus knob is presses all the way in against the microscope when doing this. Please also note, that you may have to open the clamp up a little bit with a flat blade screw drive as shown in photo d.

Figure 14. The two 4 x 10 mm screws that secure the base plate to the microscope.

Locate the two 4 x 10 mm screws that secure the base plate to the microscope & the 3 mm Allen wrench.

Figure 15. Install the drive assembly as shown. Note that the drive shaft slides over the ffk extender

Figure 16. Use the two 4x 10 mm socket head cap screws to secure the base plate to the microscope

Install the drive assembly as shown. Note that the drive shaft slides over the ffk extender shaft as shown in figure 15. Use the two 4x 10 mm socket head cap screws to secure the base plate to the microscope as shown in figure 16.

Figure 17. Use the 7/64” Allen wrench to tighten the drive shaft clamp. Please note: clamp must be securely tightened to prevent any slippage

Figure 18. After tightening the drive shaft clamp as shown in figure 17, tighten the vertical and horizontal adjust adjustment screws

Figure 18. After tightening the drive shaft clamp as shown in figure 17, tighten the vertical and horizontal adjust adjustment screws

After attaching the motor drive & base plate to the microscope use the 7/64“ Allen wrench to tighten the drive shaft clamp as shown in figure 17. Please note that this clamp must be securely tightened to prevent any slippage. After tightening the drive shaft clamp loosely tighten the vertical and horizontal adjust adjustment screws as shown in figure 18. Do Not overly tighten the vertical and horizontal adjust adjustment screws. The drive may wobble a small amount when driven, and this is normal.

Check the alignment by noting the drag while turning the right fine focus knob. No noticeable drag should be felt at any point with in the full 360 degrees of rotation. If any noticeable drag is felt loosen the Vertical & Horizontal adjustment screws and reposition the drive to a point where no drag is felt. Then hold the drive in place and loosely tighten Vertical & Horizontal adjustment screws.
