Easy way to heat a ring gear?

[Super A]

My students are replacing the ring gear in Old Ugly, and since we got it split the job has sort of ballooned owing to worn pressure plate fingers and a bad release bearing. But I digress. What is a good way to heat the ring gear to install it? I'm a little nervous using a rosebud for fear of over-heating it, and the oven in the FACS department is too far from the shop building to heat it there.....we do however have a re-purposed electric cooktop in the building. If I can get hold of a skillet big enough, would it be possible to heat the gear hot enough on the stove? They got the old gear off today and got the flywheel nice and clean so it's time for the new gear tomorrow....

thanks,
Al

My guess is that you would not have enough heat, I always lay the fly near the ring gear and heat the gear with a torch going in a circle around it. When I think it is hot enough Using welding gloves I move the gear over top the flywheel and drop it down on.

rose bud and worry none. dont go cherry red obviously, it doesnt take a lot really, so heat in circular motion to heat evenly and a minute or so should allow it to slip on, then cool with air stream once seated.

If you're to concerned about using the rosebud, you can place it in the skillet in water and boil it. It should slip on once the temperature gets to around 200 degrees. Use a clothes hanger hook to remove it from the boiling water and handle with gloves.

It doesn't need to be red hot, I've laid them on my wood burner for an hour or so and it went on well.
Check for wear and you may rotate ring according to starter location. I really enjoy hearing of students and a project like this, a lot can be learned and used latter in life.
Enjoy!

As mentioned previously, just heat with a torch, in a circular pattern. You don't need to get it all that hot, when you see oil traces start to burn off, it's good to go. When you drop it on, you'll wonder how it can possibly stay put.

I was going to say use a toaster oven, but a hot plate and skillet sounds easier.
