Stuck flywheel puller tool

Hey guys I'm trying to get my flywheel off my 2014 yz450. First I can't get the fly wheel to come off I think I put the inner protection cap on to far.

So I am trying to get the tool off and now that is stuck? Maybe I put to much force trying to pull the flywheel. How am I supposed to get this darn thing off?ImageUploadedByThumper Talk1450306588.704503.jpg

You need to leave some room between the piece that threads onto the crank end and the flywheel so the puller can actually do it's job.  If the piece that threads onto the flywheel is stuck and won't come off, perhaps you cross threaded it?  It shouldn't be wedged on there.  Now if you hanked on it pretty hard with the other piece seated against the flywheel, you may have just jammed it against the flywheel.  See if you can devise another way to hold the flywheel (hint... rope in the cylinder through the plug hole) to get that piece loosened up.

Thanx for the reply I just got them both off. Unfortunately threads now a little messed up but should be useable.ImageUploadedByThumper Talk1450307843.152052.jpg

On a side note after I got the flywheel off I noticed these marks ........is this normal if not what would it be from?ImageUploadedByThumper Talk1450308087.937247.jpgImageUploadedByThumper Talk1450308112.088572.jpg

Normal.  It's from beburring the case castings at the factory.

Can someone clarify or restate what this comment is recommending? I have a flywheel puller but cant seem to get the fly wheel off, and have been pulling very hard.  where should i leave the room for the puller to work? On the small protective nut or the large threaded tube?

Thanks!

After you take the nut off, make sure you remove the washer in there before using the fly wheel puller. That could cause issue when removing.

Correct,  the nut and washer have been removed.

Ok, got the flywheel off in 30 seconds after I knew what to do! The gap between the protective nut and fly wheel is key. I wish all of the videos I watched would have said this.

This: (see pic) This tool is on an '06, but it's the same thing.  If you run the thread protection cap nut down too far, it basically becomes a flywheel retaining nut, and holds the flywheel on the crank in spite of the puller.  Leave a gap as shown.
