Removing/Installing flywheel on 38' G.

Hello, I have a 38 G that I am restoring right now. The tractor had sat for several years and the cork gasket behind the flywheel is leaking. To get to it, I have to remove the flywheel obviously. I got the two bolts off of the flywheel already, now to get a puller on there and pull the flywheel loose. I was reading somewhere that there is a "specific" way of removing and installing the flywheel back on. I don't have a IT manual for it, but other than removing the flywheel, replacing the gasket, making sure everything is lined up the way it came off, setting end play, and tightening the bolts, am I missing something? After I read how there was the "specific way", I got a little nervous I was doing something wrong. Anyways, any input is appreciated or tips would be great. Thanks!
 
Should be a mark on the crank and one on the flywheel that you need to line up. Also there is a little pin on the back of the flywheel that you need to line up with the notch in the slinger.
 

1-800-522-7448 will have at least an operator's manual for your tractor. Don't know about the service.manual. The Duane Larson estate has field service bulletions which will contain something.
Don't use stretched fasteners or guess on the torque. That flywheel could start walking then run away.
 
V marks on crank and flywheel only on late models. So he will have machine screw into crankshaft spline that lives in extra deep slot cast into flywheel groove system. Tang on oil slinger fits into notch of flywheel which drives the slinger.

Everything covered circle k except for rolling it around until removed number one plug fires on compression stroke. Put in gear and engage clutch. Use clutch handle to move crankshaft left or right as needed, useful when setting endplay. Disengaged clutch won't move crankshaft, just belt pulley. Note any deep chamfer on any spacers behind oil slinger and be sure to place them to match large radius of crankshaft there. Not sure if you even have a spacer.
