    Clutch options

    I don't feel centerforce clutches are bad but these trucks do not have RPM which is needed to make the centrifugal weights do their job. Peter

    Defective LUK Throwout Bearing

    IdIoit is exactly right. All the throwout bearing manufacturers in the US have either closed or moved out of the country. I tried to get a bearing manufacturer out of Chicago to make us a T/O bearing for our most popular number. We use around 18,000 per year of one number so I offered to pay up...

    Powerstroke swap with 6.9 clutch

    The T19 4sp transmission has a 1 1/16" input shaft. If you bolt that up to a powerstroke my bet is it won't last a week. The ZF 5 transmission uses a 1 1/4" input shaft. Also the T19 is an 11" clutch whereas the power with the dual mass flywheel uses a 12 1/4" clutch. If it has the after market...

    New clutch kit, flywheel, rear seal

    It looks like the wrong clutch fork. The fork in the pic looks like it is for a the later 87 with the ZF5. The prongs would be to wide for the throwout bearing. Peter

    Trans noise after rebuild (new clutch and bearings)

    Some designed discs can create a gear roll over sound but the Luk usually does not. You could have a pilot bearing failing or failed which you would want to address ASAP. You may also want to do a diagnostic check to make sure your injectors are firing properly. Peter

    Performance clutch for the 6.9

    We can trade you out from the factory 11" clutch to a 12" clutch which in it's self is a good upgrade but better yet would be to go with Kevlar clutch material. southbendclutch.com Peter

    Clutch Alignment Tool

    Some of the clutch companies use a disc design that does not have what is called a free travel spring assembly in the clutch disc. The result will be excessive idol noise commonly known as gear rollover. This sound can also be exaggerated if there are any injectors not firing properly. The DMF...

    "new" ZF - Bad Vibration at idle - Very Concerned

    I would check your injectors to see if they are all firing. A bad injector or two will cause the vibration as well, Peter

    clutch failure x3?

    I feel the problem is the brass bushing you are using. We tried them back in the early 90's with terrible results. Bore the flywheel out and put a ball bearing in. PB 6303 2RS will do the trick but pay the extra and buy a high quality bearing. Peter

    LUK SMFW disc issues...

    For that reason right there is why we automatically put a 13" clutch on ours. The 12 1/4" have a tendency to come apart like that. \Peter

    clutch failure x3?

    Any wear with the pilot bushing or front bearing will accelerate the problem with the springs in the clutch disc. I am not worried about competitors or trying to sell a clutch but this is a common problem we see with the part store clutches. Heck, even in our books they call for the same clutch...

    clutch failure x3?

    The problem that you are having is the clutch disc is designed for a gas motor. The clutch disc for the diesel needs to be what is called a two stage hub to protect the diesel pulses from the clutch springs. The center of the disc actually floats and has a non-resistant rotation to the hub. With...

    clutches

    Our solid flywheel package is redrilled to except a 13" clutch as we are not fans of the 12 1/4" kits. Our kits come with everything included as well as our Kevlar bushing. Anything you buy over the phone if it ia out of your state does not have sales tax unless that company has a store front in...

    Another one bites the dust.....

    Believe you me we thought about what you suggested but the problem didn't rear its ugly head for a while. The other problem is that we would never be able to obtain a list as we sell on so many levels. warehouses who sell to dealers who sell to stores who sell to retail. There would be no way to...

    Another one bites the dust.....

    Just came across this. The clutch you have pictured was a a batch of disc that started showing up in mid 07 where the process of tempering the springs was done incorrectly by the manufacture. Unfortunately it was to the tune of 3500 pieces which is months of sales. That hurt!! Not quite sure as...

    Okay, I think I am losing my clutch.....

    Excuse me!!!!! Where do you get this information? If Kevlar is used at South Bend Clutch it is 100% Kevlar made by Tribco Inc. out of Cleveland Ohio. Owner Dave Bortz, Clutchtex and Braketex. We actually helped the company financially to get started some 25+ years ago. We use Kevlar primarily...
