This is a rather hard to find original cast iron cam gear for a 1 3/4 and 2 1/4hp Associated or United hit and miss gas engine.  It is in good used condition with no cracks, breaks, or repairs of any kind.  It measures about 5 3/16 inches in diameter and has a 5/8 inch face.  It has 50 teeth, all of which are in great shape.  It has a 3/4 inch bore and is about 1 11/16 inches thick through that bore.  The cam itself has minor wear and looks to be in good, usable shape.  Please do your homework to be sure it fits your application.   If you need a gear for your engine because yours is missing, broken, or repaired here's your chance at a very nice one.  It's ready to go to work on an engine.  It would also make a great spare on the shelf.  These are extremely tough to find in the wild or even at swap meets so don't miss your chance on it.  It would surely beat making one! The pictures tell the story.  You'll like it.  I can be reached at 262 573 193 1 if you'd like to talk about it.   Good Luck.
