Keyed Flat Washer Found

[GeorgeP1111]

When I removed the Oil Separator Plates on my CA77 motor, I found this keyed washer in the sump of the right cylinder. It measures 19.81mmOD x 14.13ID and the Key is 2.4mm wide. I looked thru all the drawings in the parts book but did not see anything that looks like it. It's keyed so it must come from a shaft, but which one? Look familiar to anyone?

Also, my bottom crank case has two Knock Pins, one 10x20 in front center #11 and one 10x20 in the rear center #3. The drawing for my CA77 shows two other Knock Pins # 4 and #5 (28/29 on theCB77 drawing) but I don't seem to have them or even see where they would go. Engine #CA77E-1023944. Are these other two pins not used here?

tnx

It is from the Neoprene Cam Chain guide in the middle of the cylinders.
4 at the crank and 1 on each end of the gears with the Kick Starter Shaft. ..............................lm

I found it!! It goes on the Cam Chain Guide Roller Pin. When I opened up my motor, the Guide Roller was just floating in the chain because the center part of the pin was gone. The drawing doesn't show it, but there must have been this washer between the roller and the snap ring... it does fit. Ok, that mystery answered . :-)

Anyone on the Knock Pins?

tnx

Wow... You beat me to it.

Ok, I haven't pulled the gears out yet so that's where they are hiding. I'll do that next.

Thanks
