Got a technical question for those who own a O.S .18 CV-RX engine.

Brand new O.S engine...

I've taken all the parts off the T-15 engine, flywheel etc.

Out of the box the O.S engine has a piece of round metal on it that covered the bearing (circled in red). Does this stay on the engine shaft? Or have I done this correctly and taken it off, and placed the brass cup (along with the small black plastic washer) directly over the engine shaft, covering the bearing?



Thanks. It's probably wrong, knowing me!
