Micro Transmission - installation manual Tools needed: Hex allen key 1.5mm / 2mm / 3mm / Philips screwdriver Step 1: remove the original screws Step 2: remove original pressure plate and shaft Step 3 through 5: remove teflon bearing and keep it for later use. Step 6: Place teflon bearing inside the micro focuser Step 7 - 8: Remove one knob of the original shaft Step 9 - 10: push the shaft into the micro tansmission and fix lightly. Step 11: Fix micro transmission with mounted original shaft to the Crayford focuser. Step 12: Check the micro transmission´s knob and fix lightly. Step 13: Fine adjustment 13.a (Left allen key) Lower the pressure on the pressure plate until the drawtube can move freely. If necessary, turn the drawtube until the shaft lies on the full surface. Now, increase the pressure onto the pressure plate until the drawtube does not slide independently in and out. Control 1: Check whether the Craford focuser runs smoothly or not. If yes, increase the pressure onto the shaft until the focuser has the desired resistance. 13.b (Right allen key) If the focuser still does not run smoothly. The planet wheel has to be adjusted also. Step 14: Loosen the planet wheel housing with a minimal turn of the right allen key. Like focusing, move the drawtube in and out while tightening both screws succesively. The planet wheel housing allows a small amount of play so their shaft can take its correct position alone. If the micro focuser still doesn´t run smoothly, the Crayford shaft or the original casting is bended. Loosen the left allen screw again (decreasing pressure onto the Crayford shaft) and vary the tension of the four small Philips screws setting the pressure plate (Step 11). Then, repeat step 13 + 14. Now the micro focuser is ready for use! Further adjustment opportunities: In some cases, play of the focus wheel may occur. The reason is a loosened set screw inside the knob. It is located beneath the rubber armour as shown on the photo: With friendly permission by Lajos Szantho |

"Unverzichtbar, wenn man fotografieren will. Diese Mikrountersetzung ist sehr einfach nachzurüsten und funktioniert hervorragend. Eine sehr ausführliche Umbauanleitung ist dabei, damit kann auch der nicht ganz so Geschickte den Umbau durchführen."
