ragman069 Posted August 22, 2007 Share Posted August 22, 2007 I WAS BACKING UP A 10-12% GRADE THIS SUMMER IN A '67 DM-800 10 WHEEL DUMP. THE TRUCK WAS GROSSING ABOUT 75,000#. ALL OF A SUDDEN, A LOUD BANG, AND THE WHOLE DRIVELINE JUMPED. I STOPPED MOVING. THE TRANNY (QUAD BOX) WAS PULLED, AND THE REVERSE IDLER GEAR LOST ABOUT A QUARTER OF ITS' TEETH. IS THIS THE WEAK LINK IN THIS TRANNY? DOES ANYONE SELL INDIVIDUAL PARTS AND GEARS FOR THE QUAD BOX? THE LOCAL MACK DEALER IN RI CAN'T SEEM TO BE OF ANY ASSISTANCE.
