The AC compressor, AC bracket, alternator, belts, right side engine mount, right side engine mount bracket, belt pulley, timing belt have to be removed to gain access to timing belt crankshaft sprocket. That sprocket has five holes evenly spaced around the side of the sprocket. You will need a special tool with that 72 degree hole spacing to pull the sprocket. Typical harmonic crankshaft pulley pullers do not have that spacing.
While you are doing that level of removal and repair, you should remove the camshaft sprocket and intermediate shaft sprocket and replace those seals.
