for those of us that don't have a torch or have access to one i have found that if you put your crank sprocket in the oven @ 300 degrees (i placed mine in my favorite cast iron pan) and let it cycle on and off three or four times it will heat enough to slip back on while doing you front 60k or for whatever reason you have the sprocket off for.

How far away from the seal does the crank sprocket sit when it is in its final position? Doesn't it rest right up against the front main RUBBER seal? I definitely would not reccomend that avenue when just cleaning everything up and a light coating of oil makes it so easy. If any of the parts are damaged, you shouldn't be re-assembling them until you fix the damage. Heat and rubber should not be mixed; at least when talking about crank seals.

I usually stick mine in front of a heater for 10 minutes.
i'm sorry i should have been very clear about this, i'm using the 60k walk through that has been provided at shophoenixproject.com and in step 25 he says
"We will now replace the timing belt sprocket. Sometimes it will slide on with no problem, but that is pretty rare. Do NOT hammer the sprocket on. You can heat it up using either a propane torch or even set it on a heater. Once it is hot enough, you will be able to slide it on with no problem, using gloves. Notice that the sprocket is not pushed on all the way, this is to let it cool so it doesn't damage the crankshaft seal. Once it is cooler slide it on all the way."
i have neither torch nor heater in my apartment parking lot. using the oven works very well and if i had a torch or a heated shop to work with i would most likely be using one of those methods.
however i'm positive that the rubber front main seal is exposed to some high temps for prolonged periods of time, and while i have not measured them, i don't think that it's going to be in danger of melting unless some ***** puts a torch to it.

300 is a bit on the warm side. Does anything on the engine aside from the exhaust manifolds even get that hot during normal operation?
that said, the sprocket lands on the shoulder of the crank snout, about 1/8" short of the seal. No physical contact, but definitely too close for comfort.
