Q: How do I remove the bearings from my RC engine?
Place your engine housing in an oven at 325°-350° for 5 to 10 minutes. When you remove it from the oven your old bearings should fall right out, if not heat the engine a little longer. We also suggest you place your bearings inside a ziploc bag and keep them in the freezer overnight. Then slip the bearings into the engine while it is still slightly warm.
