Mitchell, I don't think there is a commercially avaliable Nylock nut in that size to replace, you are stuck with using the Ferrari ring-nut.

I had to cut mine off as well, I made the socket and did the same thing as you, the tabs sheared right off. So I made another one, this time I TIG-welded a sleeve around the socket to bridge the tabs so they wouldn't break off. It worked, but the nut was so seized, the tabs just rounded off the cut-outs on the ring-nut.... Then, out came the Dremel tool and a chisle....

I guess I should have given more details. I would use an air chissel to loosen the nuts and when replacing with new Ferrari ones, the socket should hold out with a torque wrench. I would use the correct nuts, if they ever came off, major damage and an upsidedown smile.

Paul

The SnapOn radio antenna socket does not work, the puny little protrusions sheared off under the amount of torque required.

So, I cut off the nuts with dremmel tools and air cutter. For torquing it back on, I will need to modify a air wrench socket. Hopefully, that steel will be good enough to withstand the torque.

What about using a lock nut with a nylon sleeve at the end? Anybody ever did that?

Brian, the point of this whole excercise if to tinker with our toys and tools in the garage. If I were a professional mechanic, I would shell out the $75 for the socket. The way it is now, I rather tinker with a $7 socket to make it work.

It amazes me the value we place on our own time, I know that it would take me a while to locate then modify a socket, which would be at best adequate. Or, I could buy and use the right tool for the job, save my knuckles as well probably.

I bought a snapon socket for antenna mast nuts. The tool number is S6183 and it looks like it will fit. I havent removed the crank damper yet so I cant put it directly on the nut.

Whatever kind of socket you use please be sure to replace and properly torque the nut when you go back. All kinds of problems can ensue if you don't.

I am not paying $75 for a socket, I will make my own. Does anyone know what size socket I should start with?

I am getting to the point where the main timing belt lower pulley (not on the cam shaft) have to come off. I notice those funny 4-prong nuts holding those blasted pulleys on. Do I have to make one of those special sockets? If so, what is the size of the socket I have to start with?
