[Fot] LUK clutches

[Joe Boruch]

I have also been using Tilton and Quartermaster clutches for over 10 years.  I tried the single disc version for a couple of seasons, but found cracks in the friction disc, so I went back to the double disc this year.  The single disc is rated for over 200 ft-lbs of torque.  My car should be in the 170 ft-lb range, but I guess that was too much? (I am sure that 9 inch slicks don't help the situation either)  If someone has a low hp TR3/4 I have a very nice single disc Tilton clutch unit that I do not need any more.  Joe(B)

My experience with the Tilton has been the same as Johns, no problems.  It came with the car and is probably the original setup from when Jack Wheeler had it.  Don

I’ve been using a Tilton setup for over 20 years with no problems. It is a dual disk that came as a package set with the flywheel. The pressure plates and flywheel have little #1s stamped on them for proper assembly. Very nice, probably the nicest thing on my car. I replace the disks every 5 or 6 years if they need it or not. Even when I switched to a 240z trans. all I had to do was change to 9 spline disks.

FoT, 

No surprise, but in the past few years the low volume stuff has been farmed out to low cost suppliers.  Including LuK.  My clutch friends say that this business has changed consderable. You wont know what you are getting, regardless of the label. 

One of the businesses I got involved with John Deere was remanufactured clutch components. It doesnt make me an expert on the design of clutches, but it gave me some good insight in the business side. 

Rebuilding a good old unit is preferable and the materials are frequently superior. Same goes for discs.  I just provided one for a TR3 and ot had apparently superior friction materials and all of the springs replaced.   

But now there may be a forthcoming shortage of these materials. ..... 

Henry,  If you still have that core, I'll see what I can do. It may end up being better than new and far less expensive. Nothing will happen until this winter, but I am sure that is OK with you.

There have been at least 3 LuK clutch pressure plate failures in racers 
that I can document this year. All were about 5 years of racing use. 
Look at the 3 metal straps that hold the part that engages the friction 
disk to the outer shell. Mine broke at the rivet and would not 
disengage. Leo's developed a nasty vibration. Tony's started slipping. 

Also George's Borg and Beck failed, throwing a little chunk that could 
not escape the bellhousing until it made a hole big enough to escape. 
Scratch that gearbox case... 

There have been way too many gearbox pulls in the paddock this season 
because of clutches... Also having a new clutch kit ready to go in the 
race spares is a very good idea.
