Throw out bearing always makes contact?

[mpanten]

In case anyone is interested here is what I found out. This comes from Mike Forte himself not me so it should count for something.

The throw out bearing initial specs are clearence before start up with the slave fully extended. According to Mike the rod on the slave will not fully extend back to the full length (at least on his model) after the clutch is engaged and release. In other words if you press the clutch, the length the rod exteneds out of the slave will change.

If you can reach up and move the rod farther by pushing or pulling on the fork then it is working properly. The extra air gap/movement in the slave is there to allow the fingers of the pressure plate to expand. In other word the slave and throwout will return to it's preffered or so to speak natural position.

I hope I explained correctly and Mike or Brent if you are reading this please correct me if I am wrong.

If anyone is interested, there is a nice outline of the differences between "continuous contact" TOBs and "non-continuous contact" TOBs in the book Light and heavy vehicle technology by Nunney. You will see that they are two completely different animals. Here's a link that I think will work, and you should go to page 274 and start there. http://books.google.com/books?id=eL6...page&q&f=false

If I read that right, both systems are just fine.

Both are just fine. But they are two entirely different systems, with entirely different components. It is imperative that you know what system you have in your car. I know what system I have in my car (non-continuous) but I don't know what you, or someone else, has in their car. Once you know what system you have, only then can you determine whether it is set up correctly and functioning properly. So, the correct answer to the question "should my TOB be in continuous contact" is "it depends."

I'm really not trying to be difficult, but if we had the actual part numbers that would help track down what car set up they were made for. Absent that, you'll have to track down the guy that actually installed the parts and ask him whether the setup is for a continuous contact system. They're two different systems, like hydraulic and solid lifters. They both do the same thing, but they're different and you adjust them differently.

EDIT -- In other words, if you do have a continuous contact system, you should NOT install a fork return spring -- it would defeat the purpose of the whole design.
