Vibe 50 nex mystery part question

[Firefighternickn]

I bought a used vibe 50nex. I took the mainshaft and the head off, and a washer fell onto the bottom bearing block. Anyone knows where this copper washer goes? I'm thinking it might sit between the gear and the bottom bearing block

[Dave Snider]

It's a spacer that installs on top of the one way bearing and below the mainshaft bearing block. Is it flat or does ot have a lip? If it has a lip the lip installs down.

No it wasn't the mainshaft collar. The mainshaft collar was separate. That's the one with a bolt and a set screw. The part I'm referring to is just a flat small washer yellow copper in color

[Dave Snider]

I know it's not the collar, it installs on top of your one way bearing. It horizontally lines up your main gear to the pinion.

Could you please tell me if I have it in the right place then? I don't know if you can see it. It's the brass looking washer

[Dave Snider]

that looks right. sorry I was telling you wrong,In your cased and some others the spacer installs to the bottom of the one way. Most helis have that spacer in some form or another. Just make sure you have no up/down play, the main gear and pinion mesh in the same place,and the spacer installed between owb and main shaft bearing. heres a link to the manual.

Dave, Thank you for all your help. I can't for the life of me find the page with that washer on it. I have the original manual in print also, but I can't locate that part anywhere to see where it goes together.
