I have about 7k on my Con OFE, and yes there is some rattle at IDLE w/ the transmission in Neutral. I had babied my stock clutch for 8+ months while I decided which clutch i wanted, and from what Manufacture. i would put the same one in again. Everything i read on here told me that it would would have a rattle, and might even be a little grabby backing up. I put in the hydralic upgrade in at the same time, so that the wife would be able to drive it if I ever let her!... Scott
 
smitty, I would ask Peter if he would be willing to ship one of the replacement discs that are quieter. If so, I will talk to him and see if we can work something out on labor and get you taken care of.

I will have to drive out to you. I would like for you to listen to it. Does your DD make alot of noise? U have the same transmission I do.
 
I can understand your feelings/thoughts. I went with a SouthBend b/c all I hear and read is how great a clutch it is and produced by people that know what is needed with a Diesel Clutch.



I do understand how SouthBend felt the need to change their Disc design due to some failing and those customers not being to happy after spending close to 1k for a clutch that is suppose to hold up.



I also realize that many people on this site are pushing their trucks to a level that is WAY past what many of our rigs will ever see! My truck is souly modded to make my towing experience more enjoyable and more powerful. My truck will never see the drag strip or sled pulling! I never row through gears empty and power shift or anything along those lines. As many can see with my mods my drivetrain will never see high HP/trq either.



I just feel when knowing all that, and calling SouthBend and asking which clutch I should go with, perhaps they should give a little more info or ask a few more questions for us who are not fimiliar with their product.



Since my truck will only see such conditions I really wish I would of went with the old Disc design and then all this Neutral noise would not be present. A diesel is not meant to be quiet but as we know the Common Rail has come a long way from the older 2nd gen 24v's! I mean when I let the pedal out I get looks from people near by that have that "something is broke" look on the face. Other then the noise and starter spacer issue I am happy with the clutch. I just think SouthBend should ask you up front if you mind such noise and give u the option to pick the disc. :confused:



Sorry for your dislike, Feel free to call and we will get you taken care of. Simple as that. Some vehicles produce more of a torsional spike and will create more noise then other vehicles.

hmm, personally from an outside person looking in, I personally feel it to be very distasteful of a manufacturer to come into a thread where someone is having problems and swoop in like a couple vultures. There is an old saying some should learn to live by, "It's not what you do during a sale that matters, it's what you do when a problem arises. "

Now, if South Bend had blown Smitty off and told him to pound sand and that they were not going to take care of him, that would be one thing. However, you guys have not even given them a chance to take care of the customer to see if the situation can be rectified. South Bend has obviously mentioned that they have a different style disc available. I would personally try it out first Smitty so you can personally experience the South Bend customer service. I think in the end you will be happy

Now for this fine piece of "Clutch Engineering". Personally I would like to try out one of these Zooms. Maybe you guys would like to try to build one for 1100-1200 HP diesel applications. If so, I'll beat and thrash on it for you to see how well it holds up. I'll be in N. C in October for a dyno competition if you would like to see it first hand...
 
Gary from Perfection offered to look at the truck... they have some great engineering people... . Peter to my best knowledge has no engineering background... . just sort of does what he wants and makes a lot of money from it... grew up in his dad's business... BTW- his dad was one of the nicest guys in our industry... . I'm sorry he is no longer with us. .



Jim, this is getting old. In the last few years you have taken the opportunity of these forums to publicly insult me. I am sure I could pull up at least 10 posts from you. All of this stems from a meeting we had some 15 years ago. You wanted my company with a few other companies to go into a joint venture with you. You didn't like the questions I presented and thought I was rude for asking them. Well, the outcome of the meeting was none of us decided to join you on your clutch venture and you ended up taking a bath. I guess my questions and concerns were not too far off and I didn't need an engineering degree for that. I feel that working at South Bend Clutch from the age of 15 would give me a better understanding of clutches then any school could offer. Come to think of it, I don't think there is a college that offers clutches 101. By the way, I did go to school for computer programing and transportation law and economics. Did not help much with building a good clutch though. Please stop the insults and run your business and I will do the same.



By the way, you are right. My father was an awesome man and was very respected in the industry for his clutch knowledge. He went to work for his father-in-law building clutches in his teens. And had a High School education.

WOW seems someone is a little jealous! I do not know peter personally but professionally I do. Never met the guy in person. I sell a lot of clutches and mostly Southbend. One of those reasons is peter, he is very knowledgeable and willing to help with any problem that my customers are having. I deal with alot of manufactures and Southbend's customer service is by far superior.

I was taught that every vehicle was a system... and if you tipped the scales because of something you changed you had to give up someplace else in the system... every vehicle is that system and its a give an take... Often this can mean really bad results... you make a change to improve one issue and two other areas fail to meet minimum standards for some other reason...

Actually Peter I do have 2 degrees from a college, one is an AA degree and the other is a BA degree in Automotive and Diesel Technology. In addition I have extended training provided by Dana Spicer before Eaton bought them in HD Clutch Applications. And have studied a publication by SAE, Manual Transmission Clutch Systems.

We have stayed out of the business your in because I don't have the engineering I need to do it right... I'd have to throw ideas and product out into the industry and take chances... I'm not willing to do that... READ ""when you screw up... you PI** to many nice people off""

I'm sorry you've taken personal offense that I liked your father and his contribution to this industry... . he had a lot of respect with his peers... .

Jeff - I mostly deal with clutches from class 8 trucks and with the increase in HP to over 600 HP and 2250 Ft lbs of torque our portion of the industry has it's hands full... We're working with a product that was first designed over 30 years ago... when a big engine had 375 HP... I do understand HP, and torque and the formula of what it takes to hold it... . we both rebuild and now manufacture new our own design... .

With this post I've decided to refrain from posting about any of the performance clutch issues... ...
 
Smitty,



Thanks for contacting me, the offer of assistance stands as we discussed.



Mr. Mills,



If my schedule permits, I would like to meet you and see your truck on a dyno in NC, please send me the date and location. I would also like to send you an invitation to our South East Diesel Jamboree on 11/15/08, the details are on the local and regional forum. At this time Perfection does not have a system for the power output that your truck has, we have never claimed that our single plate system will hold at those levels. The issue that Smitty3500 has relates to gear noise which is a challenging issue any time you change the torsion damper design.



Best regards,



Gary Croyle
 
I would like to say a few things ... ...



I am sorry this thread has brought up some differences. That is a fact of life though.



I made this thread just as "info" on my experience with the SouthBend Clutch kit. Every truck re-acts different to product change. I just wanted others to know, not to use the starter spacer since it does not state to Not use it in certian trucks. I would hate for someone else to ruin and starter and possible flywheel! Do you know how much even remaned starters are for these trucks?! $$$





I am very happy that so many wanted to help me in such a situation. It proves that many good people are out there in this market.



I have nothing negative to say about Peter or anyone. Just that instructions need to be a tad more specific and problems like these can be avoided.



I feel enough info has been given on my part about my experince.



Thanks to All.

To all clutch manufacture's. (no matter who it is)



I was told that a stock Dodge NV5600 flywheel has a slight taper to them and can not be resurfaced, if replacing a stock pressure plate/disc due to the the other components as well, having the taper to match it, and needs replacing instead if there are any issues with them. Is there any truth to this?



I have two CTD's with different manual transmissions and because I keep mine stock it can become a problem for me when its time to replace my clutch. I have always resurfaced my flywheels when changing a clutch.
 
RVTRKN,



I'll try to measure one for you, but it will be tomorrow, I have seen the FSM reference that you are referring to.

The taper in the flywheel runs 2-3 thousands from the factory and is there for smoothness of engagement with the rag/OEM type of clutch material. Most flywheel grinders are set up with the same taper. Grinding is preferred over lathing simply because you do not need to cut under the hot spots. The hot spots are slightly swollen areas on the surface of the flywheel and the process of grinding levels off the high spots. When going with a high performance type of clutch where metal friction facings are used, it is preferred to have as flat of a surface as possible. This will allow a full contact of the friction surface to the flywheel and pressure plate. If there is a taper with this type of friction material it will be more difficult to break in or seat the clutch. It will have to wear or cut into the outside edge if the surface until it will make full contact.

I think I will chime in on this thread.



If you are another manufacturer... ... ... do not post in this thread. If you would like to discuss your product with individuals (ie. free product etc)

keep it to pm's.

If there are questions about other clutches or issues, start another thread.



Any questions, check the site guidelines: Turbo Diesel Register: The Number One Resource For Dodge Cummins Turbo Diesel Owners! - Website Guidelines"



Lets keep this professional.

Any questions, please feel free to pm me. :)



Thank you,

Brandon Parks

This is an interesting post, because I just had my starter and flywheel ring gear replaced. Here's what happened. Installed the SBC Con OFE about 2 months ago, and all of a sudden, when starting the truck, the starter began making a horrible noise. I only started it 3 times after the noise started before I pulled the starter off and inspected. What I found was teeth BROKEN off of the bendix AND the ring gear. I have a SBC flywheel, and am contemplating going back to the stock. Something has to be different about the SBC, because my stock ring gear looks new, and after less than 100 starts my SBC ring gear is trashed. My kit did not come with the spacer that I keep hearing about so one was not installed. Ideas on the problem? I'm worried my new starter/ring gear is going to get torn up now.
 
Just as a general note, I just installed a fluidampr on my 07 with G56 and a SB DD3250 clutch, and all semblance of idle or low rpm loaded gear rattle is totally gone... (Still makes a racket while the clutch is depressed in neutral, but I accept that its part of the DD design). I'm slowly relearning the fact that I have a newly re-usable RPM band again... I highly recommend this as an addition to the engine for anyone who has removed the DMF stock clutch. It really does feel like a completely different truck now.

The G-56 I drove w/sbc's 3250 was silent with the clutch pedal depressed in neutral. The only minor clatter I heard was w/the clutch pedal out.
