This is probably for R V Anderson, I have a Watts clutch pack in all three of my cars and I have a question on the height of the collar that the fingers push against, the Ford clutch is 13/16" but the Watts is a little thicker, I have the modified push ring but the finger adjusting screws are screwed all the way in, I have probably 4000 miles on this one and I may have it adjusted too tight! Any ideas? Thanks

Rick

Rick -- The 13/16" measurement should work with the Watts clutch. This handy tool makes it easy to gauge, even in the car.

You haven't adjusted too tight if you still have a free neutral, I think?
I modified the push ring and adjusted to the recommended 13/16" initially, but the clutch slipped terribly with my high compression (5.8:1) engine. Had to adjust the screws half a turn at time a couple of times after that and now it slips only uphill with a fully loaded pickup when I give it full throttle. May have to adjust more, when out of adjustment there's a risk the Watts needs replacing - if the spring is strong enough, so make sure it isn't a weak spring that causes the need to screw in the adjusting screws so much?

Roger brings up a good point. The Watts clutches RV sells come with a stronger-than-stock spring to help prevent slipping. If using a stock spring, it might not be strong enough.

The 13/16" measurement is a starting point. Often they will need some adjustment from that point, and after some use they will need an adjustment as a matter of course. When I drove my '15 Touring to the Centennial, it had a newly-rebuilt engine and a new Watts clutch with less than 100 miles on the rebuild. Fifty miles into the trip, the clutch began slipping to the point that the car wouldn't pull itself. I stopped and adjusted the clutch, and it made the rest of the 1,800-mile trip just fine after that.

OK, thanks I pulled the engine and checked the disc's they seem to be OK, the spring is good maybe I was overthinking the problem, I have a Z head, .250 cam and a Scat crank with no magnets and a Pertronix ignition, it runs great I was just concerned about the adjustment.

I figured out my problem, the ends of the fingers are worn down causing the adjustment screws to go in all the way for proper adjustment, I have some fingers that are in almost unused condition so I will use them.
