Vertical adjustment screws
Installing the Drive & Brass Clutch Plate
Use the 7/64 Allen wrench to loosen the clamp that is located on the ASI drive shaft. This clamp is
located at the end of the drive shaft as it protrudes out of the black encoder cover. Once the clamp is
loose slide it back towards the encoder and slide the brass clutch plate onto the ASI drive shaft. The
clutch plate should slide onto the drive shaft with the milled out portion pointing away from the
encoder. While holding the right fine focus knob slide the motor drive and back plate assembly in
towards the microscope, when the ASI drive shaft is close enough, position the hollow end of the drive
shaft (protruding from the black encoder) over the fine focus shaft on the microscope. Orient the
motor assembly so that the two shafts are aligned, and then push the motor assembly onto the
microscope. If you do not hold the right fine focus knob the microscope’s fine focus shaft may be
pressed over towards the right of the microscope. If this happens simply push the right fine focus
knob in towards the microscope to push the shaft back.
Press the drive onto the microscope until the side of the back plate assembly slides against the side
of the microscope, or if installing the drive and back plate separately: push the drive on until the tab
on the adjustment bar seats into the grove on the back plate. While holding the drive in place with
one hand use a screw driver to press the clamp against the brass clutch plate and press the brass
plate against the wave washer and focus shaft. Hold this in place and use the 7/64 inch hex wrench to
securely tighten the clamp. Note The Clamp Must Be Securely Tightened or the drive and
clutch may slip.
