For your consideration is an original Cam Gear for a Waterloo Boy JD model H 1-1/2 or 2hp I’m not sure which it is, hit miss engine. The gear part number appears to be K331R. It has 50 teeth, the overall diameter is 5-1/4″, the center hole is 5/8″diameter. The gear appears in great shape to me, and the cam lobe seems fine also. It doesn’t appear to have much wear on it. It has some green paint on it. Please read the following full description so you understand the terms of the sale, this will save both of us time by not messaging me questions that are already answered.

The can Koozie is used as a back drop for a size comparison, it’s not included in the sale. I do NOT allow offers on my listings. Thank You for viewing, John Tonjes Jr.
