Dropped EQ3 and damage the geers teeth

Recommended Posts

I have unfortunately broken part of the gear box of my mount when I accidentally let It slipped and dropped, from the decking to hard floor. 

It has cut the teeth of both of the gears and bent one of the shaft.

With the helps from NSAS society, They managed to take them apart and tried to find out what replacement parts I need.

They think I need to replace two gears and one shaft. 

I attached a picture of them. Not sure if the replacement of these parts the motor will work properly.

I have emailed the dealer now waiting for a reply from their supplier. 

Here is my model 

Skywatcher EQ3 Pro GOTO Mount & Tripod

Please can anyone advise what I should do ?

Oh dear, that's most unfortunate! However it's not the end of the World and those two gears are not the most important in the overall drive train. Both gears seem to be the same size and I think they mesh in the same plane. You may be "lucky" and find there is enough of the damaged teeth left to still engage whilst turning. You would have to orientate the gears so that the damaged parts do not meet. The bent shaft probably can't be straightened adequately, if you could send it to me, or any machinist you might know, and I could cut the damaged part off and graft on a new piece. This could be a fix untill you can get some replacements. I have a EQ3 Pro mount, I'll have a close look at it tomorrow.

That looks nasty!  If you can get replacement parts then everything should work OK when reassembled

Hi Pete if you look carefully, the other dish has lost quite a lot teeth, the motor drive one direction ok, but not the other. Do you think the mould, I mean the body will be ok ??? I dont want to buy a relacement part if the mount has also been damage ?

As long as there is some of the tooth width the gear should mesh reasonably well. I have some spare drive gears from a Vixen motor, I'll check to see if they are the same as the Skywatcher ones.   :icon_biggrin:

@Winniewsp. I've had a look at our EQ3 PRO today and the Vixen gears are different. I also found that the gear arrangement was different than I had expected so my previous advice won't apply. I'm afraid that the only real way forward is likely to be replacement parts. Sorry to have raised your hopes.  :sad:

I have a similar problem gears have been sheared after mounting a heavy Newtonian telescope.  Does anyone know were it is possible to get replacement parts.

Email Skywatcher's UK distributor at info@opticalvision.co.uk

explaining the issue.  Warning though, if they do not stock these then you're in for a long wait for news ones to arrive.

      Complete beginner question regarding using this mount.
      When I have tried to set up and align the mount , the goto targeting is off by many degrees.  Here's what I do - can someone tell me what I'm doing wrong!?
       
      With the power off:
      Align the tripod and mount to North and, with the clutches released, set the declination to my latitude (52deg 28' N). and the mount in the weights-down home position.
      Lock the clutches and fine tune the alignment on Polaris using the mechanical adjustments on the mount.
       
      Turn the power on:
      Set up the date, time and location, elevation etc. in the handset (noting the American Date format and Longitude first (set to W 1deg 48')
      DST = Yes
      Select 1 Star align
      Pick a star, I usually try Procyon or Betelguese depending on the time.
      The scope slews to vaguely the right direction but actually nowhere near.  It can take 2 or 3 minutes of manual slewing to centre the star in the eyepiece.  Finishing, of course, with an up and right movement.
      Finally, press Enter to complete the alignment ==> Alignment Successful says the handset optimistically.  
      Now from the object menu pick another target.  Try, say, Polaris which was where I started and ... nowhere near it.   It's the same regardless of the selected target.
       
      I have tried 2 star alignment and 3 star alignment, a factory reset before starting,  but nothing seems to work.   Once i'm lined up on a target the mount tracks nicely - it just won't go where I want it to!
      Not yet at my wits end but - Help!

      Hi everyone.
      A friend has an EQ3 Goto mount, I think it's the Sky-watcher one.    Currently, I know nothing about them, except that he's having issues getting it to work.  To the point that he's getting so frustrated with it he's seriously starting to thinking about throwing the mount away.
      He's described what's happening to me.    What he's saying is that the mount never points to the place where he's asked it to point.    He's saying that say the scope is supposed to point towards something in Orion, it'll end up pointing somewhere on the other side of the sky.     He's also said that it doesn't seem to want to track past a certain point in RA.
      I'd thought rather than simply jump in and try to help him out and get just as confused,  I was wondering if there's some check list of common EQ3 faults that I could work through to see if we can solve the issue.
       
      Once thing I do know is that he's running the mount from a dedicated tracer battery, so it maybe safe to assume that the power supply is good.   (althought it's something I'm going to double check as I don't want to miss anything)

      34 2-minute subs, no darks. Exif says 6c so the sensor was probably somewhere between -15 and -20C!
      Begging for a few more hours!

    • By Stub Mandrel
      To my surprise last night wasn't a complete write-off. I managed to get another 135 minutes of decent 5-minute frames of M31, this time without my LP filter. Total of 3 hours 55 minutes with my cooled canon. There was some streaky noise caused by drifting very thin cloud.
      The subs were much brighter and no moon plus high elevation meant I got away with it. The mix of frames with and without filter stopped the core being too badly blown out. I think I've controlled my urge to over-process this time, but any suggestions for improvement welcome.

      Hi everyone,
      I have just bought an eq3 pro. I initially plugged it in and nothing happened so I brought the cigarette lighter adapter out to the car and it began to work. 
      Just wondering is this how you charge it or do you have to leave it plugged in while you are using it? (Newbie here)
      Thanks a million
