200x transmission unknown washer

[Solid Snake]

I am placing my new transmission from Edog into my 200x and noticed a washer on his transmission that wasn't on mine. It's not in the Honda service manual or in the Clymer manual. Goes between the 5th and 2nd gear on the main shaft.

Now, even though it doesn't show it in the drawings, I have a feeling it may be something that Honda added without updating the exploded diagrams, because a few months ago when I had my old tranny apart I had a washer left over, the same exact one that is in Edog's transmission, because I just followed the diagrams in the manuals.

Anyone know anything about this? I have a cutout pointing to where it goes. I'll have to get pics tonight, have to get some batteries for the camera.

I have mine apart right now and did not see a washer there. I thought it was a little odd myself, but there definately wasn't one there.

I'd just take a close look at it, does it help a gear mesh with another? Or does it pull it back a bit? Does it take play out of something? Shims get added to trannys quite often...

[Solid Snake]

It definitely helps, the gears there spin much more smoothly. I've heard of people "shimming" a transmission, never actually seen anyone do it. How would you know where you need shims? Just something I've always wanted to know but never figured out.

I checked a trany I bought for the shift forks and it didnt have that washer.

Gears are machined in a manner that when the fork slides one gear into another, the shift dogs or lugs fully engage into the next gear. There are only a few gears in a tranny that remain in a fixed position all the time. The other gears are forced into the fixed gears to change the ratio. Thrust washers prevent things from rubbing together and wearing out. Thats why everyone should expect to see one behind just about anything that freely spins within a transmission.

Things wear and shims get added to take up that side to side wear. They are usually very thin, like .020 or twenty thousandths.

That washer may have no purpose being there but it could have been put there because it was needed to stop something from hitting or rubbing against something else. Is it simply out of place and between gear instead of at the end of the shaft on either side where there is usually a washer?? 5th and 2nd looked like fixed gears. Sometimes parts get used from a couple of trannys and it may just be an extra or in the wrong place. If you measure the thickness, is it the exact same washer that belongs at the end of the shaft??

[Solid Snake]

No it's not the one that goes on the end of the shaft, or any of the ends for that matter. I know exactly what they look like and they are in place. This one is in the only place that it'll fit, the size of it will only allow it to slide where it is at now and is too loose to be used on other areas. I'm hoping Edog chimes in here since I got it from him and it came out of a running motor. When I got the gears, they were packaged in such a way that the shafts were never disassembled, they were wrapped and taped up. So it was definitely there.

The tranny that sold you is a 85 transmission.I may have put it in there for extra just in case you were missing one.
