SBC Con.O going in....

[DIESELMAN]

My 'old' factory clutch came out today, and the new SBC Con. O is in. Seems the flywheel had a noticeable ripple to the surface, but not from wear, the new grind is nice, I'll tow with it by Saturday to see. The 'old' clutch otherwise looked new, but slipped under load (200-400RPM 6th gear, 65MPH, pulling 7400 lbs), the new clutch seated quickly and does not.



This is what comes to mind, could the undulations in the flywheel surface, only a few thousandths, but noticeable to the touch, have caused the slippage under load? The waviness is NOT wear.



Since the SBC clutch is a LUK's clutch , what makes them different? The pedal feel is identical, the appearance of the friction material is identical, only the rivets appear that they may be different and the metallic in the clutch face appears to have more copper, maybe.



So, SBC, is this Con. O in fact a LUK clutch for an extra couple hundred dollars, or what are the real differences? How is the increased plate loading achieved?



BTW, this transmission is one big mother!

It's ALL in the rivets.

Did you put the box on too? No, the clutch is definitely different than a stock Luk.



My pedal actually feels lighter than stock.

Hey Fred - Box is in, if the pedal is lighter, I don't notice it, but it was pretty light before, and I've never been bothered by clutch pressure on anything.



Box is in, but I have sprung a minor leak at the fuel pump high pressure output fitting, right at the union nut, enough to wet the side of the engine. I haven't tightened it yet, can't get a wrench on it,,,, must have been the EZ on 4 that caused it



The clutch is smooth a silk now, I'll be in Phoenix Saturday to grab my Desert Fox that I'm using for the Alaska run, I'm setting up a shop in the back end of it, expect 11,500 to 13,000 lbs. I'll know then how well it works, I don't anticipate any trouble.



BTW, send me an invoice/receipt.

I tries the LUK and the CON O works better
