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

Doesn't really fit the 466, the steel base of the gear is about 2 or 3mm higher which means it doesn't mesh properly with the horizontal bevel gear. On the 466 there is no height adjustment for this sprocket as the base of the sprocket sits on a bearing mounted within the frame of the machine. If it's too short you can readjust it, but if it's too long the only way is to machine, the only possible adjustment is that it's a horizontal bevel gear, so I had to machine the steel base to get it right interlocks. It's fine for me because I had the tools to do it, but it's not a substitute for form/fit/function. I have no idea about other models.
