Clutch Adjustment on 2006 Peterbilt

If you're by yourself set the brakes, get a bar or something that will hold the clutch pedal to the floor. Tools needed are a large flat blade screwdriver or small prybar to roll the engine over at the bell-housing access port at the bottom of the bell-housing. Roll the engine over until you see the adjuster on the clutch. If it's an easy pedal by Spicer there will be a yellow tab with a bolt head on it. 3/4" wrench or socket will fit that. Push that adjuster in and rotate clockwise until you have the desired freeplay, generally 1.5 to 2" of freeplay is good. Be sure that adjuster pops back out once your clutch is adjusted. Hope this helps.

 

That would be a 5/8 wrench or socket.

 

And you should get an 1/2inch extension bar to measure the space between the 'forks' and the relaese bearing, this must be 1/2inch, then adjust your freeplay which should 1 1/2inch on the pedal.
