Hell, it's not even a motorcycle. A friend has an MTD Yardmaster riding mower with a flat tire. Tubeless, but it's a sidewall cut. He can't get the wheel off. Rear wheel, left side, 1 bolt in the center. Pulled the bolt out and now it looks like the next step is to get a big hammer and start knocking the wheel off from the inside. I am just no willing to take the next step. The whole thing looks under engineered and probably won't receive the big hammer appraoch well. Any suggestions?
My MTD snowblower has a small retainer clip around the axle in addition to the bolt that holds the wheel on. I didn't see it the first time I took a wheel off. Not sure if the lawnmowers have that too. If there is no clip, I would get some penetrating oil (kroil or generic) and soak it for a few minutes. That stuff works wonders.
