If using a torch you need a heat gun or the heat indicating temp sticks. We need to keep an eye on the temperature when heating things and keep the torch moving rather than make red spots on the ring gear. This can change the heat treating of the ring gear too.
Cooling the flywheel will help too. Then assemble the two parts quickly.
When i was building the cnc vertical turret lathes we would install tapered roller bearings this way and some were between 12" up to 30" in diameter. The cones would go in the freezer to -20 and the roller bearing would go in an oven with spot light bulb shaped "heat lamps" to heat it. We had to move quickly when installing the cones and then the heated bearing into the machine. The lathes i worked on had 36" to 144" chucks and weighed up to 200,000lbs.
I started taking the 154 apart and got a good close look at it finally. The "PO" jimmy rigged a 10si alternator with the starter /generator being supported on the outside of the hood by a wooden block. He let the s/g fall to the outside and stuck a 10si alternator inbetween the s/g and the engine. He did reduce the wrap of the belt on the s/g pulley so i'm not sure if it had enough traction to work. I took it all off and i'm sure i'll end up with a box of extra parts. I'm finding the 10si alternators are popping up all over the place lately too. I just ordered the 105amp 1 wire upgrade kit for it too. I figure with the 105amp's and a 1,000cca battery i'll never have a shortage of 12v power.
