There have been a lot of reproductions over the years and a lot of failures. A lot of debate on this forum too.  A big article was done once on the development of some good ones but I think they were all sold.  There was one on eBay recently but the quality of the casting looks awful.  Never used one myself, always prefer a good used one.

Jack: You should go to   Search   at the top of the page and type in Cam Idler Gear. It will show you the persons name who reproduced the gears in 2009. From reading the articles brought up in search. the key to duplicating the original Cadillac gear is using the correct formula for making the bronze with the correct hardness. As you might already know, there was a cam gear made in the late 80s that looked great but made from the wrong bronze. These gears failed because of soft bronze. I would think there are still some of those bad gears out there and I don`t know how you tell the difference. What is the problem with your cam gear?   Bill
