Sorry It took so long, I was looking to see if your transmission was synchronized or non synchronized. In which, your case, it is synchronized.


If you have a partner to help with the adjustment, it is alot easier, otherwise, you will need something to press the pedal all the way to the floor so you can do the adjustment.


Freightliner requires 1.5" of pedal travel in the clutch pedal after you adjust the clutch. If your measurements on the clutch look good, but you do not have 1.5" of free travel at the pedal, then you will have to adjust the clutch linkage. If you bought this truck used, hopefully the previous owners are smart and adjusted it the correct way.
