Serious clutch finger wear
Anyone have any ideas on this? I had 57,000 miles on an SBC and when the engine went, found the fingers worn bad. Replaced the clutch cover and throwout bearing. It now has 16,000 miles on it and while it does not need a new cover, the fingers are wearing like before.
I do not ride the clutch. What can cause this? Will a spring on the pedal help. The pedal lays on the cylinder. Has anyone had this problem? In the current form the fingers will wear out in 60 to 80,000 and need a new clutch. It's a shame, the grind marks still on the surfaces, but the fingers wearing off.

Just thought of something, is there a difference in the 1999 to 2001 slave cylinder, or more correctly the master and slave? It is a 2001, 1 3/8 shaft six speed in a 1999 with the 1999 cylinders.
The last two throwout bearings were supplied by SBC. I also know that they are stock Dodge bearings.

Where does the clutch engage at compared to the stock engaugement point? If it's earlier in the pedal travel, it's feasible that the clutch isn't disengaging far enough and causing wear. Or, if it's disengaging too far into the travel, it would make sense that it's always got pressure on from the throwout bearing. I'd give Peter a call and see if he's heard of anyone else with this issue?
Another thing, I don't remember seeing an adjustment anywhere for the clutch. Is it even possible to adjust it?

I may not have anything to contribute to this thread, but, H_I_D ! STAY AWAY FROM MY TRUCK!. lol
You have the worst luck I have ever heard of,, except one of my customers. I swear, I bet you are the type of person that could buy gold, and it would loose value.
Brandon,
It isn't really possible to adjust the clutch, although you can, (So I've been told).
Hope you get it fixed H_I_D. I have no comments. Teach me something.. (again)

Ok I won't have any way of knowing for many thousands of miles but... I spent a couple of hours looking at this and that, no way to really measure it out of the truck. I took a chance and ground about 1/8 inch off the slave cylinder rod. If it was riding because it was too long that should take care of it. There should be plenty of throw for the clutch, I guess I will know after a while. I went back to the LUK clutch that was on the five speed and it had the same problem and would have worn out. Thanks for the input.

Haulin in Dixie: I'm having the same problem. The originals fingers were extremely worn, and now the factory replacement ones are wearing too.
I want to rectify this problem , as I'm putting the expensive Southbend in as we speak.
I called Southbend, and they figure it's the hydraulics. They say, when you release the clutch, the pressure plate fingers push the bearing back, and then there is a 'bleed off' hole in the master cylinder to relieve the hydraulic pressure. They figure that hole is plugged , and leaving too much pressure against the bearing.
They also say, that the bearing will always ride against the fingers. That's just the way hydraulic clutches operate. But at the same time, with basically little pressure, about a pound or so. With the kind of wear I'm getting, and by the sounds of it, you too, the master cylinder is keeping too much pressure against the bearing.
This all, of course, is if pilot and release bearings, fork, etc.,etc. are in good shape.

Interesting concept and probably is the problem. I had the front brakes on my goldwing start dragging and that was the problem with it. Should be able to poke it through. On the wing I put a little bigger hole in it, never gave any more problem.

and also.....inspect your vibration dampner as they can go bad ( as YOU probly know) all thoe I do not know if it would affect the other end of your eng.
2- The for fork can be installed backwards.
3 When I had all the troubles with mine, (oil cooling jets).I found the t.o. bng worn concave from the fingers....so.....
.....what would happen if a thrust bng. was real loose ?????. Lots of end play and bumping and riding on the fork??
B4 I took mine apart it had lots of end play-(thrust gone).
