ALTERNATOR BELT TENSION
-The belt tensioner is designed to work within the travel limits of the boom between
the two fixed end-stops 3.
-Visually check the travel of the boom. If the pivoting boom stop 4 touches one of
the two fixed end-stops 3, check the condition of the alternator bracket, the belt
tensioner and the return pulley.
-Check the length of the alternator belt and change if necessary (see: 3 - MAINTENANCE:
H - OCCASIONAL MAINTENANCE).
-Do not check the automatic tensioner spring tension if the alternator belt tension
is correct. In case of doubts, contact your dealer.
AUTOMATIC TENSIONER SPRING TENSION (IF NECESSARY)
-Place a 1/2" socket wrench in the square of the automatic tensioner 5 to slacken
the belt and remove it.
-Release the force and remove the socket wrench.
-Make a mark A on the pivoting arm, measure a distance of 21 mm (0.8 in) from this
point and make another mark B on the fixed part of the tensioner.
-Place a torque wrench, with the centres of the pulley and the tensioner aligned and
turn the tensioner until marks A and B are aligned. The torque should be 20 N.m.
-If necessary replace the automatic belt tensioner.
-Refit the alternator belt (see: 3 - MAINTENANCE: H - OCCASIONAL MAINTENANCE).
