Removeinner wing nut and filtering element. Clean the filterbowl and all other components using 40 psi pressure.Apply a small amount of grease to the seal. Thenrefit the element. Reassemble all components.The alternator fitted to the 700 Series engine isdriven by a drive belt of a specific design. Use onlya Perkins POWERPART drive belt. If this is notdone, an early failure of the belt may occur.Press down the belt with the thumb at the center ofthe longest free length and check the deflection.With moderate thumb pressure – 45N (10 lbs.) thecorrect deflection of the belt is 10mm (3/8 in.). Toadjust the belt tension loosen the pivot fasteners (3)of the alternator and loosen the setscrew (2) of theadjustment link. Change the position of the alternatorto give the correct tension. Tighten the pivotfasteners of the alternator and the setscrew of theadjustment link. Check the belt tension again toensure that it is still correct. If a new belt is fitted,the belt tension must be checked again after the first25 hours of operation.82 TX51-19M-1-SM 01-29-0257.4400.0100
