transmission help

[timfost85]

I'm in the middle of reassembling my M5R1 tranny after rebuild. I'm almost ready to connect the main shaft with the input shaft, but this piece in the picture below is throwing me off. Can anyone identify it and let me know if it's supposed to be there or if it's possibly part of a broken bearing or something? I couldn't find it in any of the parts lists. Thanks for your help!



I'll update when I successfully get the shafts put together.

Looks like a ball bearing race to me.

It was near a needle bearing that feel apart...

Tim always put something in the picture to show the size of the part... a dollar bill or whatever.

Man, I am not sure what that is. Are you sure it is even from your transmission?

I am just getting my own M5OD back together, had to tear it down completely to replace the output shaft for a 4x4 conversion, including pressing the gears off and on the shaft. I didn't come across anything that looked like that at all.

It was right near the thrust bearing where the input and main shaft join. I think I'll assume it was part of the broken needle bearing and not worry about it any further...

That honestly looks like a bearing retainer for a bicycle part, like a headset bearing. (I'm a reformed professional bicycle mechanic.)

Really, it looks like it held bearing balls, not needles or rollers. It also doesn't look large enough for anything in a transmission, unless there's some small, light part of the M5R1 that I don't know about.

Does your service manual show anything like that? Is there any chance it came from something else and got mixed into your tranny parts by accident?

 

[timfost85]

Nothing in the parts list matches this. I am about positive it came out of the tranny as I distinctively remember thinking it looked unusual when I removed it off of the shaft... Honestly, if no one here had seen it, I'm going to assume it doesn't belong and we'll see how it goes back together without it.

Thanks for your input. I feel like maybe I'm not going crazy after all!

The only thing I can think of is that is may have been part of the cage for the pocket bearing. That's the one at the head of the output shaft, that rides inside the rear of the input shaft. That part is a common failure on the M5OD because of it's location it is the hardest thing for fluid to get to. It's just about the right size to be half of the cage.

I have to agree that looks identical to the bearing holder you would find in a bicycle headset. holds ball bearings

it is the end of the "cage" for the "pocket bearing" that centers the outpt shaft pilot in the input gear.
