It's super simple
REmove belts
Take out center bolt
remove pulley (sometimes a puller is needed, other times you can kinda pry it off gently. BE CAREFUL as if you pry hard you risk cracking the front cover/oil pump.
Remove the seal with a screwdriver/pick/similar tool. Wipe the area out, and then gently tap the new one in. If you can use a larger socket for a 'driver' that would help keep it even, but slightly tapping it in a circle works great too if you are in a pinch. DO NOT force it.
Reinstall it in reverse order, and you'll be good.
FWIW: Seems like you damaged the OEM seal when you put the aftermarket pulley on.
It is NOT your rear main seal...that's in the back between the trans and engine.
