I recently bought a used KO Propo PDS 2413 IDS servo, the previous owner had shortened the servo lead to fit his set up. It was way too short for mine so I opened up the case to solder a longer one onto the main board.

When I removed the bottom of the case the top cover which encloses the gears came off at the same time, taking some of the gears/mounting posts with it.

Now for the embarrassing bit – I can’t work out how to get the gears back in the right order! I feel an idiot for having to ask for help on what it usually a simple task but this has really got me baffled

Could anyone post/send me a photo of the gear arrangement in their servo or similar one? Alternatively does anyone know of a site with this sort of info on it?

Many thanks and a happy new year!

The only 'cover-off' photo of any servo I could find is in the link here:

Ill go take a pic of a standard gear set-up.

that horizon link appears to be a weird servo with extra gear's....i dunno RC dad what servo is that ?


normally there are only 4 gear's in a servo.....As Rc Dad has shown some have more then 4 gear's....ive never opened a KO so i don't know the specific config.

It's a DS9411 Ultra Torque. Only pic I could find with the top down. Yes there appears to be a few extra gears there

Interesting....personally not a fan of JR but some seem to like them.

Sorry Spike, my google-fu failed me. I wasn't able to find any exploded view, diagrams, or manuals with pics of the gears for KO servos.

Thank you for your efforts

Google doens't often let me down but there doesn't appear to be any images available of this servo (or many others) with the "top off" - I can sort of understand why. I've emailed KO customer service to see if they can help.

In the mean time I've left the servo to one side, it was beginning to frustrate me and that's not a good way for me to work. I've been busy over the Christmas break so I'll have another look at it tonight.

Thanks for your help

Spike

Spike- that pic that was posted should be pretty accurate. I have used nothing but KO servos over the years. I can tell you that gear 2 goes in without the shaft, then put the shaft in. Because of the bearing.. if memory serves me.
