We have just purchased a used Case combine and are installing a Crary system on it. We had one on our MF platform for a number of years and never had any problems.
I purchased one for my 17.5 ft, 1020 bean head. I love it! It is easy to maintain and parts are free for one year. My brother has 1 1_2" cut CIH for his 1020, and he has to constantly remove shims to keep it tight.
