I bought the correct replacement ring gear for my flywheel and I cannot get it to go on. Its so damn close, but no cigar. To my wife's dismay, I put the flywheel in the freezer over night and cooked the ring gear to 450 degress...no success. Is there a trick to this? I do have access to press, but am afraid to ruin something. Help!!!:CRY:
We always set the ring gear on the flywheel,then use oxy/acet. torch and heated the ring gear cheery red in four equal spaces on the ring gear,then use a ballbeen and tap the ring gear on. Usually worked quite easily and when it cooled down the ring gear was locked unto the flywhhel.
All I have is a map gas torch...I dont think Im gettin it hot enough...no where near cherry red. Ill have to get a buddy with a real torch.
We replaced a lot of them at the marinas where I worked. used the torches as HWORRELL says. Go all around the perimeter and keep heating it until you can tap it down into place. Mapp gas probably isn't hot enough.

Im just a shade tree mechanic, trying to work with what I got...:o
Thx for the quick feedback guys!
Had some trouble finding a buddy with a rosebud torch on the wknd, so I gave it one more try this morning in the oven. This time I put the ring gear on the floor of the oven, instead of the rack and let it bake for about 35-40 minutes at 450. It slid right on!:3dSMILE: Just figured Id post an update, thanks again guys.
400 degrees seems to be the magic number for just about anything that nees an interferance fit----ring gears, sleeves , bearing races in alum housings, etc
