A small glitch.. then OK
on October 4, 2012
The Celestron motor drive is very cool and very, very "small"....
Received it overnight.. as usual.. from Amazon.com
Had already downloaded the insructions from The Celestron website. so I was familar with the unit and the installation instructions....
Proceeded to install the unit... OH MY!!! the RA shaft is TO BIG for the coupling.. a defective unit.. you say.. bad engineering....I was NOT a Happy Camper ...
Called Celsetron "CS" and was greeted with a 20 minute wait.. was finally connected to a fellow.. explained the issue... He said.. I don't know what the problem is as I have a unit right in front of me and the hole is fine.. it should fit the RA shaft with no problem... I mentioned it looked like the hole had a metal sleave which made the diameter to small to fit.. .. Too bad.. He said...send it back.. to us or Amazon..
So.. being a "problem solver" by nature... I removed the coupling from the motor shaft and took a closer look at at the rubber coupling which has two screw holes... one at each end.. I reversed the two screws and it fit.. The screws were assembled in reverse order at the factory... in China..of course.... as they are both the same diameter.. How "nice" for them.
So being a good "Amazon" customer... to help save my fellow customers some grief.. I called back to Celesrton and informed them of my findings.. AND... What do you think they said... OH YES... we are aware of that problem.. Well.. it appears I talked to the guy who did not get the memo.. as the second person was female... who knew all about the issue . good job... young lady.. and she expalined the fix... I called to tell them about..
When you receive your unit.. look at the rubber coulping at one end.. if the large finger screw is on the end with a metal sleave .. it is reversed... remove the coupling from the motor shaft . and reverse the screws.. replacing the small "allan set scew" at the end end with the metal sleave... THEN... the other end of the coupling will fit the RA shaft.. the one with the finger screw as as it has a larger diameter.
This may sound like "greek"..BUT, when you look at the unit you will understand.. and the unit will function as designed..
If the end with the "finger screw" has no metal sleave..you are "good to go"..
I was told a significant number of unts have this flaw.. the luck of the draw...for you
Hold your applause.. please
