Stick it in 4th gear and set the hand-brake hard. No need to remove the Valve cover. IMHO, better than holding cam gear as load is going direct through the crank. Impact gun should buzz that puppy off no problem.

 

I like using a weighted Hard Plastic mallet. If pulley is stubborn, go to Lordco or your favorite Auto supplier and get some " Freeze Spray ".  Used for shrinking rusted bolts etc. Spray the center of the crank with the stuff, crank shrinks and off pops the Pulley. Safer and faster than heating the pulley.

You might get the pulley of without removing the radiator if you used a pull bar and a socket instead of an impact wrench. I've not done that but it maybe possible?

I've used a 1/2" breaker bar with a 3 foot pipe over the end. Came off in a jiffy. Safer to remove the rad though...

 

Craftsman Tools Lifetime warranty was great for situations like that. No questions asked, but sometimes a raised eyebrow from the salesman as he looked at the snapped off swivel... and then handed you the new Tool.

Replaced the seal, and after consulting the how to modify book I removed the oil slinger. I hope that was the right choice. So far she's not leaking and I'm pretty happy. This motor certainly has a little more go!

The cranks bolt came off like butter with the impact gun... The crank pulley. That was another story. But we managed in the end with a hammer and some wood, with some help from the starter as there wasn't many good angles to get it from. Thanks for the help guys, and the incredibly quick replies!
