Marv every old IH dealor I ever went in had a oven in the shop just for heating those pulley's. If heated in a oven it will not get hot enough to hurt the seal at all. There will be a lot less danger of breaking an other pulley. I have insalled dozens of them this way and never a problem with melted seals. Put the pulley on the oven rack and turn on oven any where between 300 and 400 degrees and heat about an hour then slide it on. You have to do it quick as the pulley cools down enough in only a minute or so and will not go on. The first one I installed, I drove it on with a hammer and block of oak, thought it worked fine until a year later while cultivating tobacco the crank just gave out. After removing it was obvious that it was broken half way across for a while. I suppose I cracked the crank with the severe hammering it took to drive the pully on. I learned this oven trick from a IH mechanic that worked on Farmalls for 47 years.
