How do you remove the magneto from a 79' arctic cat el tigre, do you need to use a gear puller?

You will destroy the flywheel if you use a gear puller. You must use a flywheel puller. It's a bar with a round section. A large bolt goes in the center and it has three holes that match the bolt holes in the flywheel. You insert the three 6mm bolts then tighten the large bolt and give it a tap with a hammer. Off pops the flywheel.





You can buy universal pullers from places like Dennis Kirk or any snowmobile shop. You can also build one with piece of plate steel, three small holes and a hole with a welded on nut in the center for a 1/2" bolt.
