for just talking about a product you like?

 

Yea, some dude ripped me up good. Made me feel stupid....

 

he must not of liked that brand. i guess, i still have a re-serfaced friction disk in mine with whatever clutch it had when i bought it, thats all that was wrong with it when i got it, 75$ fix plus some time.

 

I am kind of looking down that road myself. I work at a company called Orbitform, we build all kinds of riveting equipment. We sold southbend one of our milford riveters not to long ago. We have built automated clutch riveting systems for eaton, asin, and and bunch of other companies. Our lab guys have done low volumn production on a lot of clutches so if the sachs is not destroyed I am going to try to reface it. I have search some old posts about refacing the sachs, anyone else tried it?

I am not sure why someone would have burned you about valeo, they make some of southbends friction materials and are a huge OEM supplier.

 

I've got a valair clutch and like it so far. The clutch was in the truck when I bought it so I'm not sure which one it is, but it holds what I throw at it. And they are pretty good priced also.

Thanks, that's great info.
I will probably be kicked off the site tomorrow because I sort of inferred that Lary Ellis (CEO of DTR) was bagging on valair because SB is an advertiser on this site, and he was just trying to protect the relationship!

 

Ooops. I'm mixing up Valeo and Valair.

 

So I just toughed based with this company,
http://www.tribco.com/about.html

Going to see what their reccomendations are, they have created clutchtex material which sounds very good, kevlar fiber in a polyamid composite. It says they reface and disks, we will see.

 

We have been working with Tribco and their Kevlar for 35 years now. We actually helped them with the testing in the clutch industry before it was released. They have Clutchtex and Braketex. It is an awesome product and we use it a lot in the semi, agricultural, passenger car markets.. However, It worked well in the diesel pickups until the power/torque began to rise. It has its limitations in torque capacity and requires a lot of plate load. It however is quite expensive and in your situation, I would think to reline your old disc, if it is in decent shape would be a better option for the dollars. The Sach disc once unlined will look like swiss cheese. Not alot of area to punch for buttons. There are also fins on the OE disc that create a cushion called marcel. This helps with the engagement of the clutch. Kevlar, if over slipped will burn and turn to ash but the property of the material will help with engagement where the marcelled fin is not present. We have relined Sach disc's as well as new ones and we can put any style of buttons on them. Feel free to give us a call.

Peter,
I have heard on this site and others that your single disk feramic won't clamp down "no lift" shifts, but the 13" Valair will. I need a clutch that can handle occasional speed shifting at 35PSI with 350HP and 800lb/ft (currently, about 100 more HP with water/Meth).
Is this info accurate?
Thanks,
Mark

 

Okay I have a new mission, I have in my hands a complete set of Eaton fuller super button ceramic facings from a 14" clutch with four facings per side. I actually have a dozen facings almost all eaton facings have a standard design & rivet hole mounting pattern. Super buttons can be seen here:

So here is the mission. Disassemble the sachs clutch, remove the facing mounting plate, reverse engineer the Eaton design down to 13". Have a new facing mounting plate waterjet cut to mount four of the eaton super buttons with a Sach center hub hole pattern. Rivet the Sachs center section back together with the new friction mounting plate, switch to internally dampened dual springs. Once the center hub is installed the rivet the Eaton super buttons on and give it a try. Only cost is my time. Pressure plate loads are similar, who knows what will happen!
