This primary saved the day. After 2 full days of research I found out that the 02 660 primary WILL WORK on my 01 grizzly 600. Alot of people are still running the 600 machines, and we all know parts are hard to find and some are unavailable. I could have spent $80.00 for weights another $30 for sliders but my sheave was worse down and in bad shape. This complete primary clutch I purchased for $65 dollars and my machine runs like a brand new machine. I also purchased the 660 belt as its shorter and I wanted top end speed and power because I trail ride and dont do mudding. When I do go mudding I throw a 600 belt on and lose top speed and gain power. I hope this review helps someone who went threw the same problem I did and saves them research.
