How to properly adjust Eaton clutch with hydraulic linkage

As with any clutch adjustment, you always do the internal adjustment first. So this depends what type of clutch you have, but generally you adjust for that 1/2" clearance between the release bearing and clutch brake. The hydraulic portion should never have to be touched. If the free play isn't right, there is normally some kind of adjustment between the clutch pedal and master cylinder for this.
Here is a link to Eaton's service information.

Your " freeplay" on a hydraulic linkage is almost non-existant. A good indicator that the clutch is out of adjust is the clutch brake starts to go away from the floor. Also note when your engagment moves to the top of the pedal travel. Any adjustment on the hydraulic side would vary by OEM and often there is no need or way to adjust. Heavy is spot on and do the 1/2" first and run it.

 

I just use a long 1/2" extension to test. No need (also no way) to really adjust pedal in hydraulic system. If you are down to only 5/16 after 4 months, someone is a pretty good driver!

 

A really good simple gap tool for bearing to clutch brake is a hacksaw blade. Most standard hacksaw blades are about 1/2 wide. Then you can turn it sideways and hold it so it is flat between the brake and bearing while someone holds the clutch pedal all the way down to see if the bearing is squeezing against the clutch brake.

 

Where's the OEM location on the semi and how do you adjust I have a Volvo 2007 with 475 Cummins and a 18 speed Eaton transmission with a hydraulic clutch if you can respond back to me as soon as possible I would really appreciate it thank you.
