I have a transmission that came in parts and I noticed it has a Watts clutch setup. The disk appear to be fairly new as the ink stamping on them is still visible on the fiber disk.I have been searching for the instruction for them here on the forum and the internet but not having any luck. The fiber disk are all alike except one is thinner than the others and I want to make sure it is in the proper location. Any help would be appreciated.
Thanks Mark, exactly what I was looking for and the videos will make this a much easier job.
Are Watts still being made/sold?
Check with R.V. Anderson.
RV is making the '25 & earlier ones. Last I heard, he had not yet begun to make the late '25-'27 ones.
BTW Glenn, those instructions posted above are a bit generic. There are different instructions for the '09-'25, and the late '25-'27 Watts clutches. I'm sure that RV would be glad to send you the proper instructions for your clutch. Or I can look at them when I'm at my shop tomorrow if I know which years of clutch you have.
I just watched the video posted above, by Mike Bender and Bill Howell. It gives a good explanation of how to install the Watts clutch. The only discrepancy I saw was that Mike installed the cotter pin in the clutch drum bolt in a way which would prevent its tightening up, rather than loosening. Other than that, it's very informative.
I wonder about what it says in #7, put disk with lining on top or outside? I would think it would be better to have a steel disk between the clutch ring and lined disk. Or is there a mechanical reason to put per the instructions?
Mark - there's indeed a mechanical reason for putting the lined disc on top closest to the clutch push ring. If you put a steel disc on top you'll get a torque between the clutch push ring and the driven plate - the holes in the driven plate will be worn oblong after some use and eventually it will be unusable since the adjustment screws in the three levers won't touch the pins in the push ring.
The fiber disc is driving through the brake drum and the driven plate and thus the push ring is connected to the brake drum. The steel discs are connected to the engine through the clutch center, so that's why there'll be torque between the push ring and the driven plate with the disks in the wrong order.
I was thinking more along the line of the larger outer disk to give the clutch ring more surface to grab as narrow as it is.
Never mind, I forgot the clutch ring does not spin, so it only needs to press down.
