PLEASE HELP ! I looking for a 3004 motor but with metal gears (They have to be the same size )

Hi!

I require your help regarding a problem I’m encountering.

Arcade animatronic

It uses a futuba S 3004 servo motor with plastic gears witch are striping out in about 5 months
I need the same size motor , but with metal gears

I tried to order a motor by doing a cross search using the s30004 part number and i got a really small motor.

Is there a motor size chart or diagram explaining the differences between motors?

I know im a noob at this. I work for bass pro shop in the maintenance department .
We are one of the few B.P.S. with a Arcade still working ( if i’m unable to keep it running they will tear it out for more sales floor) PLEASE HELP ME SAVE THE ARCADE

Thank you so much in advance for your help!

Hey @MadPainter

A similar servo that could fit your needs would be the following, which has metal gears:
