'78 DT175 Flywheel Removal

Any suggestions on how to remove the flywheel on the above mentioned bike. I removed the flywheel nut and tried a generic puller.

I have a 2 armed generic puller and i tried that and I had no luck. Basically snapped one of the pivot bolts of the puller while trying to torque the flywheel off. No movement on the flywheel.

Trying to remove as I have no spark and I want to check out the points, hard to tell what kind of shape they are in when the flywheel is on.




I had a '77 YZ400 that I had one heck of a time getting the flywheel off and I had the correct Yamaha puller. It pulled the threads right off of the puller body. I ended up trimming the body of the puller a little on a lathe to get to some fresh threads and shaped it a little to get the maximum thread meshing. Next, I used a welding torch (don't fry anything under the flywheel!) and gradually heated up the flywheel and quickly screwed the puller in and tried it again. After about 3 tries, it finally popped off. Check the Dennis Kirk catalog and see if they have a different STYLE of puller. Some are more effective than others.

After the (official) yamaha style puller is fully threaded and tight,give it a 'pop' with a brass hammer. It should come off..

And what size do i need the one from the link is a 27x1 with LH internal threads, will this work?

Sorry the listing is not clear, but the puller you want fits the following and more:

M27 x 1 left hand thread sounds correct to me if your bike is in standard trim.
