CB350 engine rebuild EXTRA PART?

[captainjmash]

So I recently rebuilt the top end of my CB350 Type 1 motor. At the time I was also dissembling the frame as well.
Once we were done putting the motor back together we found a part that may or may not be part of the motor?


Looked through all the schematics and can't figure out where it goes. Any thoughts?


Thanks!


Sorry for the presence of Mr. Blurry Cam

Thrust washer from your cam. A very necessary part.

Thank you very much!

Glad I asked, was about to put the motor back in the frame this weekend.... guess I have some more work to do before then.


Thanks again, you saved me from a lot of pain.

how thick are those washers (#2 in the diagram)? the one that is posted is much thicker than .1 and .2mm washers that are represented and sold in part #2 of the diagram

 

[Sonreir]

Thrust washers are 1mm and 2mm, not .1mm and .2mm.

not according to my diagram

.1 mm? That's awful thin!! lol

Can't be the camshaft thrust washer, those are paper thin. Honestly, I really don't know if that even belongs in the CB350 top end and I've built several of those motors.

whats the inside and outside diameter? looks like a frame part to me... possibly off the rear axle?
