Review on HONEYSEW Singer Models: Replace Your Vertical Top Shaft Gear #155819 for Models 247, 413, 416, 418, 457, 466, 477, 478 by Shantel Griffin

Putting a new part into the sewing machine from the box was a real challenge. I should have just come out and sent it back at that moment. After installation, the resistance was so high that it was clear that the engine would not run. I ended up plugging and unplugging the piece a few times, sawing off the bottom piece by piece until it fit well enough for the sewing machine to run smoothly. It's in the car now and works fine, but I don't think the installation should have gone that way. When this part is sold out (and I can't wait for that moment) I will purchase a part from another supplier to replace it. Lesson: Read reviews before you buy
