I'm trying to replace the front end seal of the crankshaft on a '92 Dodge Dakota with a 4cyl. OHC engine. My only problem so far is that I can't get the crankshaft sprocket off. I have a puller, but the sprocket has 5 holes so it won't align and there is nothing for it to push against (since the sprocket covers the end except for the bolt hole). I thought about partially screwing in the center bolt to push against that but that would still leave the matter of the puller not aligning. I would really appreciate any suggestions you might have. Thanks.
