Thats a really good idea! I've got a few old 6-gears I'm going to assemble and I'll be using your mod.
You said 2.55mm wide on the brass ring? Sorry to sound dumb but what is 2.55mm in inches? You had me at 3/8 inside diameter but lost me when you went to mm!
Also, where did you find the perfect diameter brass tubing?

I've already fitted the flanged bearings and circlips in the outdrive gears. Don't fit the unflanged bearings. The outdrive hole in each of the gearbox halves is drilled out to 1/2 an inch. The brass rings have an inner diameter of 3/8 of an inch and slide over the outdrives and stop the outdrive gears from floating sideways. You only want them wide enough to let the 3/8 by 5/8 outdrive bearing seat properly and allow a minimal amount of sideways clearance. The 2/56 screw in the left gearbox half stops the outdrive bearing from working loose. The right hand bearing is held in by the motor plate. Any questions just ask.

Gearbox halves together. Note the bored out outdrive hole to clear the brass ring.

I'll be adding a Jammin Jay diff assembly soon.

The correct width is actually 3,55mm or 0,1398"
1" = 25,4mm
I made my spacers from round stock alloy
turned the outside down and bored it out

I have been thinking... which is dangerous by the way!... But why not shorten the shaft the bearing rides on? There are plenty of threads inside it for the screw that secures the bearing... Lopping off a bearing width of the shaft seems simpler then making a spacer.

You need the spacer to hold the new outer bearing in place so it will stay at the edge of the housing
the felt gasket hole is 5mm deep and the bearing is only 4mm wide

I could see a spacer if the bearing was threatening to fall inside the case, or to keep the out drive from sliding outwards due to no catch. I am just trying to simplify the setup I guess, the flanged bearing is held by the circlip but the standard shaft allows the bearing to slide in and out a bearings width due to the length of the shaft.
With the shaft cut down the bearing should not be able to slide in and out.
The outer bearing fits into the dust recession, it can't slide all the way in due to the molding on the transmission, it however could slide out which a simple screw could prevent..
Any cut spacer to my knowledge is more for preventing the outward movement of the outdrive then the outer bearing from falling out.

Okay. Just to clarify things.
- Orangemazda, 2.55mm = .100". I bought the brass tubing from the K&S stand at a hobby shop. The stock number is #136. It's 13/32 outer diameter with a wall thickness of .014". Take an outdrive with you to make sure that it fits inside the tubing.
- SnoopMax, I rechecked the brass ring width and mine are 2.55mm. I am using outdrive bearings that are 10/51 or .196" or 5mm wide. If you are using 5/32 wide bearings that would account for the 3.55mm width of yours.
- Chris, the brass ring does exactly that. It stops the outdrive from moving outwards because it butts up against the inner part of the outdrive bearing. I didn't use the button head screws inside the outdrives.
I hope this helps.

Ohh yeah that explains the difference
Didn't know you used a wider bearing

Your car really turned out awesome!
Hey, I also used your transmission build method...it worked out awesome! Thanks.

I'm glad it worked out for you. The transmission mod came from Radio Control Car Action mag. I only borrowed it.
