Ok.

I'm almost done repairing my Robonova.

But the servo that was sent back to me from Hitec is for the top right leg.

I needed it for the top left leg!

I called and told them about it, and they said that you can switch the sides in order for it to go on the other leg.

Is that true, and if so, how do you do it.

Thank you!

I imagine that requires you to unscrew the case, rotate the circuit board 180 degrees and then screw the thing back together again. Check out the thread in this forum titled "Inside HSR-8498 pictures" for what you can expect to find once you open the servo.

The only difference is that the wire comes out of the other side. Remove the bottom cover of the servo. Break out the tab on the other side of the case for new slot. Dress the servo wire wire flat across the bottom of the PCB where there are no soldered pins. Adjust grommet to fit new slot. Then replace bottom cover.

The right and left leg servos are the same just ROTATED 180 flat plane. Both servo horns face inside, Both idler horns face outside, Both servo cables are at the outside top. Check you existing servo Hi-Tec labels and you can see the orientation.

You will need to change both plates on the servo to include the triangle fixing point. The servo gear side needs the deep piece and the control board side uses the slim piece.
HTH.

:( how do you remove the circuit board without breaking it?

You don't need to remove the circuit board!!!!!!! Do what Marcus said. Just remove the plastic end pieces on each end of the servo. Then replace with the correct ones just like the original servo that was in your robot! Us the other servos in the legs as a guided!

Never mind!

I already did it!

Now I have a useless servo!

Great!

It's funny how no one is ever in the chat room when you need help.

Did you bust the board or something?

It should be a simple operation to configure the servo case.

You don't understand.

The wire is on the top right, but on the back!

I need it to be on the top right on the front.

The Hitech logo is supposed to be on the bottom left facing upward.

I understand that.

I.............

I don't understand that by switching plastic pieces in the box, that it will correct it!

There the complete opposite of what there supposed to be!

It's hard to understand without a photographic example, and I do not have a wire to transport pictures to the site right now!

I'm probably making it harder than it is, but I just don't get it!

If you cannot help, Ill understand, but something this minor to worry about is just plain rediculious!

Let me know if you can.

Thank you.

If you are swapping the same servo from on leg to the other, you do not need any of the spare parts.

The servo is simply rotated 180 degrees about its long axis.

The only physical difference is the cable comes out of the wrong side.

Fix it as I described like this

The servo will move in the opposite direction, but this is fixed in the software.

Ahhhh!

Now I see!

I was making it harder than it was!

So all I needed to do was pull the wire over the center, and slide the rubber thing down the wire in order to fit.

180 degrees is harder to understand than lay wire across circuit board.

I thought I was supposed to flip something over 180 degrees like the circuit board itself.

Anyway, Thank all of you for your help and support!
