I ran into issues taking the engine case apart with the flywheel. The fly nut was stripped and i had to drill it out. after drill the nut out I discovered the threads for the puller were to damaged to use. so i tried pulling it with a 3 jaw puller and the flywheel bent instead of popping off so I had to cut the flywheel off with angle grinder I tried to steer clear of the coils underneath but nicked them enough to have to replace those as well. :(
