You can send it to Meade -- but very expensive-- or you can buy a complete new focuser from these people-

Meade 2120 (basic) az knob turns but does not turn the fork. How do I fix this? Siderial motor seems to work.


There is a small set-screw near the focuser shaft. Is it tight?

Also you may need to open up the focuser and see if the gears are not stripped.

The focal tube on my Meade DS 114 has several stripped teeth. The auto-focus skips and jumps! Where can I find a replacement part (Meade no longer carries them) OR how can I repair this; ie, create new...


You will need to buy another focuser like one of these.

Meade DS2102 Telescope lost teeth for focusing in and out


It might be easiest to see if someone is selling one on Craig's list or ebay.  You might be able to find one used where the telescope is OK, but the motorized drive is broken and replace the telescope.
Here is the contact information for Meade:

You could try calling them and see if they will sell the part you need for the focuser.  The focuser is called a rack and pinion focuser.  From your description it is hard to know if it is the long linear gear on the draw-tube (the part that holds the eyepiece) or the gear on the shaft of the focusing knob.  You will need to be able to describe that to them.
I hope that helps.

The teeth small pinion gear on the focus knob shaft are stipped


No. That's one of the trade-offs with cheap models, they can be fine but have absolutely no spares back up.

All you can do is to check whether the 'scope is covered by a manufacturer's warranty.

Mirror lock


Possibly the shaft has jammed. Follow this link for a source of good information: http://www.mapug-astronomy.net/AstroDesigns/MAPUG/ArhvList.htm

From their files:
The locking knob has a gear on the inside end of its shaft. It engages teeth on the outside edge of a large metal disk connected to the mechanism that locks the position of the mirror on the central baffle tube. Rotating the locking knob one direction rotates the large disk to tighten the collet on the central baffle. Reversing direction loosens it.
The teeth do not extend all the way around the large disk. So sometimes the locking knob gear jams to a stop before the lock is fully engaged. Soon after the GPS scopes first started shipping Buck Harley discovered that in such cases you can remove the locking knob with its shaft and gear, then reach in and rotate the large disk with your finger. Replacing the locking knob will now allow sufficient rotation to fully engage the lock. If you happen to move the large disk in the wrong direction, then just repeat the process and move the disk in the other direction.
You don't need to tighten the lock down hard. Just a little snug is enough. You should not attempt to use the coarse focus knob while the mirror is locked. Damage to the focusing mechanism could result.
This design is intended to precisely hold the mirror position. So, yes, it is meant to allow effective use of a separate guide scope by eliminating mirror flop when in the locked position.

Stripped gears on the focuser


Meade will not have parts, focusers are always replaced as an entire unit-- but if the mirror is still good you can buy a replacement focuser here:
