So I went out today and located a very cheap toaster oven. I used this oven to heat up my cases to install the bearings. I monitored the heat with a thermal gun, and when the case temp reached about 300-320, I pulled the case from the oven. I had my bearings laid out and ready for what case I was doing. Then after squaring the bearing up, it literally fell right in. It was pretty amazing and super easy. The only bearing that gave me a little trouble was the pilot bearing for the clutch actuator. Other than that there were no problems . It's a very effective way of installing the bearings without damaging them.
