In waiting for my seal and gasket set to arrive, so i can address the same issue. Mine dies not have a balancer, big bolt and a pulley with 2 threaded holes. With a harmonic balancer puller you remove pulley By pulling with bolts in threaded holes. Then the cover bolts and lastly the cover. Knock out old seal and drive in the new one. I glue gasket to cover,grease block side of gasket and loosely install cover. Push balancer/pulley on so seal will be centered and snug a few timing cover bolts, pull pulley off and finish snugging cover. Re-install pulley and tighten crank bolt. That should cover it.
