I am having a bugger of a time getting the new ring gear on to the flywheel on my 48 8n. First off I had to use a zip cutter to remove the old gear. I then ran out of acetylene trying to heat up the new gear and it still would not go on. I then tried to put the ring gear in the oven for 1/2 hour at 400. no go. Next I tried putting the flywheel in the freezer overnight and then brought the gear and the flywheel down to a local garage where they used their acetylene torch to no avail. The gear was almost cherry red and still it would not go. I have inspected the flywheel and noticed that there is a groove where the ring gear sits - I would guess that it is about 0.010" deep by the thickness of the ring about 1/4" or so. Has anyone seen this before? I have brought the parts down to a machine shop and asked them to measure the pieces to see if the ring will ever expand enough to fit. I may get them to turn the flywheel down so the first part of the wheel is the same diam as the area where the ring sits. Any ideas out there?
