clutch adj.

It's kind of hard on volvo because the service window is so small. If u bump the engine u will see the bolt come up u need a big screwdriver to get the clutch in the right place so u can adjust it u can do this by turning the flywheel from the bottom the adjust bolt needs to be a little bit passed bottom corner of the clutch fork for easy access then someone has to press the clutch as u take a 5/8 wrench put it on the bolt at the same time you have to push the bolt in with the screwdriver using the pressure place as a prying point turn clock wise u have to alternate the ends on the ends on the wrench you do this until you have about 1/2 inch to 3/4 space between the pedal and the floor. That's the best I can explain it.

 

When you bump the key and the bolt goes up all the time the clutch is not installed properly , the bolt bust point same direction as counterbalance on the crank shaft
Most Volvo truck use Eaton fuller transmission and it do not mater if it is in Volvo or other make it is the same transmission maker
