## What is wrong

ON CERTAIN TRUCKS EQUIPPED WITH A SAF HOLLAND SIMPLEX FIFTH WHEEL, THE LEVER ARM PIVOT BOLT MAY HAVE BEEN OVER TIGHTENED.  AN OVER TIGHTENED PIVOT BOLT CAN DISTORT THE PIVOT BOLT SPACER SLEEVE, WHICH MAY PREVENT THE FIFTH WHEEL LATCH JAW FROM CLOSING AND LATCHING SECURELY AROUND THE TRAILER KING PIN.


## What can happen

THERE IS A POSSIBILITY THAT THE PIVOT BOLT CAN BECOME LOOSE WITHOUT THE DRIVER'S KNOWLEDGE.  WHEN THIS OCCURS, THE DRIVER   COULD DRIVE AWAY AND THE TRAILER COULD BECOME DISENGAGED, INCREASING THE RISK OF A CRASH.


## The remedy

DEALERS WILL REPLACE THE PIVOT BOLT AND SLEEVE WITH A HEX HEAD SHOULDER BOLT AND WASHER FREE OF CHARGE.  THE RECALL BEGAN ON JANUARY 28, 2008.  OWNERS MAY CONTACT MACK TRUCKS AT 1\-800\-528\-6586.
