Don't know about a 'dust cover' but the speedo drive snaps its lugs whenever it's removed (unless you are very very careful). the lugs and drive are ceramic and just break. They revolve (or not when broken) inside a magnetic hub and send a signal to the speedo. The Yamaha replacement version (from Wemoto etc) have plastic lugs which are much more robust.

When you put the new one on, put in plenty of lithium grease, otherwise it makes a racket.
