Is there a way to hold the flywheel thrust washer from slipping out of alignment upon reassembly? Had put in a lightened flywheel on my 620 monster. upon start up noticed a noise coming from this area I had just worked on . Upon disassembly discovered the mangled washer. I was thinking about laying down a layer of grease then laying washer on top. Any suggestions?
That's what I do.
+1, grease on the flywheel side.
+2, grease inner side.
I also measure when correct assembled top crank-nut,
then l KNOW if washer is good or not.
Alt cover bearing failure is a heartstopping noise...

Please explain what you mean by measuring assembled top crank nut ?
I think he meant measuring from the end of the crank snout to the outer face of the nut.

Yup, w digital meter.
I made this same mistake when attempting to install my Yoyodyne light flywheel. And I used high temp grease under the thin washer. Problem is, the new aluminum flywheels' splines were a tight fit over the crank and required me to hold a 2x4 over the new flywheel and whack it to get flywheel to go onto the crank. This process dislodged the thrust washer...and required it to be reopened and redone. ( I farmed it out after messing it up- only 2nd time I've trailered my bike, upon a mess up) ;D My (super experienced) Ducati mechanic told me he made the same mistake decades ago on his 1st LW flywheel install, so I felt better . Great idea w/ the measuring- I couldn't tell it was off by looking, prior to reinstall of the alt cover.
