Fl60 clutch- SINGLE OR DUAL?

How do I identify if it is a single or double disc?

Each is a different adjustment.

 

My truck is a 1997 Freightliner fl60 with a 5.9 Cummins and eaton fuller 6 speed transmission fs5306.

Here's what's happening.

I bought the truck and the previous owner has me very dubious of anything that he has done.

He told me that he replaced the clutch maybe a few years ago something like that.

The clutch comes out all the way at the end when you let the pedal out. When I first brought the truck home it was hard to pull out because it wanted to jump and lurch.

Under the truck looking at it I cannot determine whether it is a single disc or double disc. I'm not sure there's any way to determine that sitting under the truck looking at it.

I adjusted the clutch for the 3/4 inch for the single disc. To refresh anyone's memory this is done the opposite of the big trucks it does not have a clutch brake.

Now, that adjustment is correct, for a single disc anyway, but the forks have no play. They're supposed to have 1/8 of an inch, and they have no play. I have not measured the complete travel of the release bearing as of yet, but it feels like it's binding. Now I have to go through everything else because maybe something else is binding but that's the situation.

The throwout bearing took insane amounts of grease. It's quiet I don't hear it whining or carrying on or anything else.

I unthreaded the top part of the linkage where I can get to it near the engine, and it's just about all the way to the end. There's about zero room for adjustment, but I think on the other end you can adjust that?

It may be slightly better how it feels but it's still right at the end when you let it out.

If I can't identify whether it's a single or double disc, given those circumstances that I've described, do I have the wrong adjustment?

Should I adjust it to the inch and 3/4 for The Duel Disk and see if that's the correct adjustment? Will that make the pedal come down lower to the floor and maybe set it so that those Forks are in the right spot/ better spot with play?

Since I can't have any faith in what the previous owner has done, it would be really helpful if I know exactly what adjustment I need. Then I can determine what else needs to be done from there.

I appreciate the help.
