I am sick of my slipping clutch, I am most likely going to buy a Newby clutch but I thought I would check to see if it were possible to adapt a UCE clutch to fit as Newby's are expensive.

Any ideas?

Hi Charles, you would at least have to change the hub to fit the splined gearbox shaft. To do this there are various methods, depending on the measurements. I don't know if they changed the clutch sprocket in any way or if it will fit with the old chain.

I guess you would have to have both to compare.

Have you tried the Barnett clutch discs, stiffer springs, and ATF Type F in the primary case?

I have heard that Newby clutches are a little cheaper if purchased from Newby's directly.

Hi Tom, I tried stiffer springs this worked to a degree but made operating the clutch lever impossible, I use ATF F, not going to worry about Barnett discs as others have tried them and they haven't worked.

Thanks Adrian, I have been in touch with Bob, you save $100 by dealing with him direct which is good.

Andreas the clutch sprocket on simple observation looks very similar.  What are the various methods for changing the hub?

Hi Charles,
if the diametre is smaller, you could just rebore and broach it. Maybe eroding would be a way, too. If this doesn't work, you might bore it even bigger and weld in a fitting pice. Another possibility would be to change the shaft, but I guess that would be the most difficult way.

P.S.: If you have an original 59/60 Chief wiring harness in you possession, I could very much need some info, too ;)

Thanks for ideas Andreas, someone on the Interceptor site was pretty skeptical a UCE clutch would help as numerous UCE owners have trouble with them which I had not heard about.

I don't have any insights regarding your wiring issues other than I used to have a wiring diagram for a Chief and I just can't find it anywhere.  Pretty sure I got it from a member here but I just can't recall as it was some time back.  Sorry not much help.
