Fly Wheel Removal from an electric start lawn mower


I think its great that you are wanting to do some repairs on your own. I did some research and was able to find a link to help with your project. I am also adding a second link in where you can enter the model number of your mower and a parts list diagram will pop up to give you a better view of parts break down. I hope this helps while you wait for your expert response.

Great links for information. I have a manual for the mower and generally do all the work needed on any equipment around the house. But it's been so long since I worked on a mower doing this kind of work and didn't want to damage the flywheel. I did find three holes in the top of the flywheel that were pretty close to the center, about 3/4"-1" away from center. I also had a steering wheel puller in my tool box that had slots close enough to the center to be able to use it. I needed to drill the holes slightly larger to fit the metric bolts of the puller and then tapped the holes. Put the puller on and in just a few screws the flywheel popped off. The key was severely sheared off about 80-90 degrees. Off now to get parts and get this all back together before it gets dark, yeah!

Thank you for your question.

I am sorry you are having a problem with the mower. If the flywheel on your engine does not have any holes, you can use a two-jaw puller to remove it. If you do not have a two-jaw puller, you can check with your local auto parts stores. They may have the tool to loan out. Once you get the puller hook one jaw on each side of the flywheel and tighten the bolt in the center. Just turn it until it is tight and hit the end of the bolt with a hammer. This should break it loose. If you cannot get a puller, you could use a pry bar and hammer. I have found a video that shows how to do this method. Click here to watch the video. Just be advised you run the risk of damaging the engine using this method.

I hope this is helpful.

If you do not feel confident repairing this problem yourself, then you can have it repaired by a Sears technician. Here is a link that will provide the nearest drop-off locations: Sears Home Services .

Thank you for using Manage my life.
