|Micro focuser assembly parts||Step #1 - Place inner bearing housing into outer race body|
|Step #2 - Insert 3 ball bearings into housing.||
Step #3 - Insert micro drive shaft into inner housing with the
indent area inserted first.
|Step #4 - Slowly pull up on micro shaft||Step #5 - Inner race housing will "drop" into place when properly centered|
|Step #8 - Drop in ball bearings using tweezers||Step #9 - Add a drop of light oil to outer ball bearing race rubber O-ring|
|Step #10 - Screw outer race cover by hand then finish with snap ring pliers||Step #11 - Adjust pressure until there is no end play then turn another 1/8 turn. There should be no slippage when turning the micro focuser and holding the gear down with your finger. I found that placing the unit in the freezer for an hour would reveal expected dimensional changes and the focuser would slip based on the adjustments at room temperature. While still cold tighten the race enough so there is no slippage when turning the micro focuser and holding the gear with your thumb. This should now be under the correct bearing load for wide temperature variances.|
