unless i'm missing something you have 3 holes that the cover mounts to, the top one looks fine but a bolt is broken off in the hole, the lower one looks ok, the front one is torn in half, get the bolt extracted, get some JB weld, and a new chain and sprockets , use JB weld on the one that is torn and 3 new bolts, let the JB weld cure overnight before trying the clutch, just glue the bolt into the torn boss, and with a new chain n spkts you wont have to take it off for a long time, problem solved
