how to adjust clutch in my freightliner

my truck has a cummins m11 and a 14709ll trans could someone tell me how to adjust the clutch in it please.. i took it to the shop and they said they didnt have time and i need it done so ill try it my self if theres no special tools needed..thanks mike

truck is a 1997 freightliner fld

 

thanks i had read that 1 but didnt know what clutch adjustment to use cause some say use a bar ..but thanks again mike

 

i just got from under the truck and its a bit diff. from what most are saying...turn the adj. bolt clockwise and the cluth goes away turn it couterclock and it adj. fine..also the bolt is held in place with 2 flat metal straps the 1 on the top comes off and the bottom 1 stays on and you turn the bolt ...i took both bolts off and looked at them and the bottom bolt has the big adjuster bolt coming throught the top and you cant take the adjuster bolt off the metal, but you can take the whole assm. out and it has a small gear on it..anyway does this sound right or is this something thats not right????? the clutch feels better then it did but may have to go under and adjust just a little more cause i turned it the other way first and had nothing at all....thanks for all the help too guys paying 50.00 to adjust a bolt i can do helps keep the cost down ..mike
