I have an older meade LX2000 EMC 10

The main problems encountered with the mechanics of the telescope centre around the mechanical swarf, grease compound, the liberal use of grease and the quality of machining of the main DEC and RA gears.
1. Remove the motors from the telescope. Be careful when removing either motor as there is a compression spring between the motor mounting frame and the worm shaft assembly.
The RA motor is located under the telescope body, removing the 4 screws and 2 Allen bolts will allow the bottom cover to be removed, thereby allowing access the the 2 Allen bolts holding the motor in place. Unplug the motor from the main PCB before removal.
The DEC motor is in the the fork arm containing the clutch and fine DEC adjustment control. (Never to be used with power applied to the scope). Remove the 3 small Allen screws holding the plastic cover plate in place and the DEC clutch knob to allow access to the motor. Remove the RJ45 connector located inside the telescope fork arm. Then remove the motor by unscrewing the 2 Allen bolts holding the motor in place.
2. Remove all grease from the motor worms, especially around the RA motor's magnetic pulse detector and the permanent magnet built into the worm shaft.
3. Remove all grease from the main DEC and RA gears, making sure to clean into the gear teeth.
4. Lightly re-grease with a Molybdenum Disulphide based grease (Castrol MS3 is great for this application if you can get it)
5. Assemble in reverse order. But before doing so, carry out the electrical adjustment above then, (a) relocate the the RA and DEC control PCB's in the vertical plane thereby gaining access to their respective backlash Allen screws. Adjust for 20thou max clearance when in final position. Note:- the DEC adjustment screw has to be replaced for a longer unit complete with a thin bolthead as this adjustment has to be carried out with a spanner....there is no room for an Allen key adjustment here.
6. A drop of Loctite must be applied after adjustment.
7. The final part of the process is to run in the gearing. Apply 12 volts to the motor wires, either at their respective plugs or to the motor direct. Allow to run for 2 to 3 hours in each direction by reversing the battery polarity to bed the teeth engagement. Remember to release the clutches.

I was given a Meade DS2130 reflector. Everything seems to work fine except the scope doesn't move in Altitude. The motor works fine and the white horizontal worm gear and vertical white gear turn...

ONLY Meade will have parts-- usually they want you to return the mount to them for repair-- call them here:

Ok, please no laughing though. I just inherited a C-8, from my Dad who used it regularly until about ten years ago. He says the only thing wrong with it is there is somthing wrong with the clock drive but...

No -- Meade does not support that scope anymore-- but if you are mechanically inclined dis-assemble the base of the drive and check all the wiring-- and it is still possible (maybe) to buy a new motor if it is actually burned out. More than likely you will find that the worm gear is not properly engaged inside and is turning but not moving the gears.

There is a DEC "fix that you can buy at here:

Complete dis-assemble instructions are available here:

Yes it is possible to adjust them.... but you will need to dis-assemble part of the telescope to get to both worm gears.

Equatorial Mount problem. Gear at latitude adjustment (not the worm gear) is busted. Need a replacement.

Only Bushnell will have this part. Contact them here:

My Meade 90mm refractor with autostar has a stripped gear, crappy little nylon gear that drives the worm gear that rotates the telescope. Can I get relacement gears or do I have to get a new drive system....

No one but Meade makes parts for this scope. Do you intend to have a custom GEAR machined??? This will be more than just sending it back to Meade; which you will need to do to get it repaired.

The worm gear could be loose inside? or the clutch has grease on it.

There is a DEC repair kit available on here:

Backlash on scope tube meade lx90

The washers are there for a reason-- there is an adjustment screw for the worm gear-- and the Dec axis works off a friction clutch when you tighten the knob on the fork arm.

Are you talking about the center bolt on the tripod that holds the telescope on the tripod-- ??? If you overtighten this it will interfere with the rotation of the telescope....and can break the motor.

Here is Jan's LX90 web site with disassembly instructions and pictures--
