robbe rodeo or reely kaiman gearbox replacement

youmagine

2016-10-01: part 2 updated to leave a little more gap for the gear wheel. The original gearbox started to break down and disintegrate on the reely kaiman, so I decided to sketch out a brand new one. After several trials, this is the final outcome. Make sure to start with the diameter check to ensure the bearings fit properly and the 550 motor fits smoothly into the hole, then take some time and print. You'll need some M3x8 screws to mount the two housing halves together and M3 x 23/25 to attach the motor to the gearbox. I cut the threads using an old-fashioned tool, so the screws are tight in the thread. As long as the gear-wheels remain in perfect condition, this is a simple way to get the old toy up and running again. Add some good grease during the final assembly process. I use wheel bearing grease for best results. Have fun
