Southbend clutch!!

Con OFE

I installed a Con OFE in my 06. It does rattle at idle with the clutch disengaged. I doesn't do it all time and is mostly when the truck is cold. The fact that mines not the only one that does it makes it acceptable to me. The clutch works great. With the upgraded hydraulics the pedal pressure is the same as stock. The clutch grabs a little on start but isn't to bad. Live with the noise, the Con OFE is worth it. Jeff

Had a 3250 sprung hub 12cb DD clutch installed and the noise from the G-56, particularly in 4th and 5th at low rpms and minimal throttle were not good. Called Peter @ SB and he advised over filling the transmission a quart, which helped some, but not much. Ordered a Fluidampr which I'll install next week, but in the interim I got rid of about half of the harmonic noises just by adding some Lucas fuel conditioner to the fuel. It apparently smoothed out the engine to the point that the noises from the G-56 are much reduced. My wife even noticed the difference and commented on it. It's really pretty acceptable now and a pint of Lucas to a tank, (8 oz to 25 gallons after the initial pint) is pretty cheap to still have the benefits of a clutch that you don't "walk through" just by depressing the accelerator pedal a little...

Very good information. Thank you.

rattling OFE and G-56?

Yours is the first report of rattling I've read with the G-56 and OFE. What could be rattling with a single disc? Peter?

Wow, this is an old thread. haven't been on here much lately, but good to see the old threads still kicked around. I've run my DD set-up pulling a 10K trailer from Alaska to Illinois, no problems. No slipping, ran awesome.

Mine is the rattling G-56 and Con OFE. I didn't think I was unique. It doesn't do it all the time. I have no idea what causes it. I have been told that it's nothing to worry about so I don't worry.

I'll report on the Sprung disc in a week or so.



I had the solid Dual disc. Very noisy. I loved it. Sounded like a big rig, especially when shutting down,, WOOT. hehehe. However, it did get old after hours of idling. Had to shut the truck off more often than usual However, he groan the drivetrain made at 1,400rpm with 25Pounds of boost would make you weep tears of torquey joy...



Update to come.
