Review on Boston Gear Pitch 0 625 4 100 by James Holker

I figured the 3/4" gearing in the front would be no problem to fit it through the input/output gearing on my Parks planer substitute. Unfortunately I had to grind the back of the gearbox flush with the hub. Once completed it fit like a glove and worked like new. The price was right and the quality seems to match the original equipment. Nice that this exists.
