These are from last time I changed belt the little square is where battery sits and the black cover has to come off to get to top of pulley as well. Think 20 some screws had to be removed including 1 that mounts engine to deck of mower. Just to change a part that WILL fail the rest of mower is great now that it has gotten used again after sitting for 2+ years. Carb was a mess still had old gas in it and it gelled and stuck the float and needle. Can of gumout and brass brush fixed that.
