Yes, pull the covers, make sure the crank & timing gears are lined up, then pull the belt & crank gear.
It's hard to tell, but you/we need to see the condition of the end of the crank, preferably with a straight edge against the side to see if the crank is OK.
The crank gear "may" need to be replaced as well as the crank pulley. The 2 surfaces (at least on the newer ones) should be flat where they mate up.
I would also look to replace the crank seal while it's apart since it looks to be leaking oil.
