Re: RA and DEC motors

 

Good for you to upgrade your system.

Some notes:

The Oldham coupler has 3 parts: the two metal ends and a plastic center part.? You want to keep that entire coupler as the new system you will need new motors and cables and Gemini, but won't have the coupler.? (If you are trading in your G-1 for a reduced price on a G-2).? You definitely need the new cables and motors for the G-2.)

The coupler metal ends...one fits the gearbox drive output shaft that's 3/16 inch diameter, the other end fits the worm's 1/4 inch shaft.??

The gearboxes you can re-use, but its probably a good idea for you to order 2 new ones.? The new gearboxes have screws to allow you to open the gearbox to clean it or re-lube it. Over a long time the plastic rear panel can crack from the weight of the motor.? It's always good to have a spare gearbox in case of trouble.? Your existing gearboxes are probably quite old.?

Have fun,
Michael

I am seeking a rectangukar type motor, just to use for testing my repairs if those older G-1 units.??

Hi Micheal,

Ive hit the jackpot tonight with all the info! Thank you for letting me know if the gearbox and motor will fit in my MI-250. It looks like the Oldman coupler is the only question mark at this point. I assume I can place it on the new motors. I went to our neighbors house, and explained to him the problem with the diode you helped me with earlier, I asked him if he had an opinion, and he said he would go ahead and get a whole new retrofit kit. As my finances have become better since last week, I will be buying a Gemini 2 retrofit kick, instead of repairing the Gemini 1. Thank you for your offer of service, however! Losmandy will be in possession of my RJ 45 motors in a few weeks.

Clear Skies,

Paul
