What in the world!!!!

you are either going to have to get a strap wrench or a flywheel holder or an impact,the torque on that flywheel nut is 115 ft lbs its tight!

HOLY ft lbs Batman!!!!!!
Thanks for your help. Have you ever used a PJS 550 case? I have found a few on the web at a fair price. The only prob. is they do not use the stock stator/flywheel cover. You have to make your own. Thanks again

You will gain nothing by using a PJS crankcase,crankcases hold the crankshaft and the cylinders on a 550 thats about their only function.
 
Well I got the case apart and pulled the crank out. All of the bearrings and seals looked good except for the seal on the front crank bearring. It is the little rubber band looking seal. It had a 1/4 inch gap cut out of it. Like it had split. Case looked good. Only a few minor scratches, but nothing that s going to affect anything. No cracks in the case. Time to clean er up, replace the pistons, put er back together and run er till she pukes again.

If you need a full rebuild, I would but a 650 engine off of eBay and an adpter plate. I wouldn't put a bunch of money into a 550 engine. Just my opinion. Then again I have a nice 650 engine I am looking to put in a 550...

If I was going to do a swap I would put a 750 in it. All I need for my 550 motor is pistons and top end gaskets. Not much at all.
