90 Dodge Spirit; Crankshaft front sprocket/oil seal - HELP!

Trying to get the sprocket off the front of the crankshaft of this
2.5L SOHC non-turbo engine. Engine is still in the car. Pulleys,
timing belt covers, oil pan, valve cover, and the center bolt are off.
Been trying a harmonic balancer puller with a breaker bar on the
center bolt,won't budge. The sprocket is behind something else, looks
like the illustrations for the DOHC engine. The manual shows a
sprocket with 4 bolt holes for the SOHC;what I am looking at, where
the main pulley mounts, is 5 bolt holes. I've tried heating it with a
torch, still won't budge. What am I missing - is there something I
need to do to take off this thing that is in front of the sprocket?

 

Which manual are you using?

VERY POOR IDEA.

 

You need the Chrysler front sprocket puller. A steering wheel/harmonic
puller won't work.

Also don't lose the keyway as it could fall off when you pull the crank
sprocket
