1997–2000 Oshkosh S Series Recall: VEHICLE DESCRIPTION: FRONT DISCHARGE CONCRETE CARRIERS WITH 6- OR 8-WHEEL…

The defect

VEHICLE DESCRIPTION: FRONT DISCHARGE CONCRETE CARRIERS WITH 6- OR 8-WHEEL DRIVE DESIGNED TO OPERATE OFF-ROAD IN DIFFICULT SOILS AND TERRAIN THAT ARE BEYOND THE CAPABILITY OF CONVENTIONAL REAR DISCHARGE CONCRETE TRUCKS. THE FRAME RAIL FLANGE IMPINGED ON THE HEAD OF ONE OR MORE LOCKBOLTS WHICH ATTACH THE ANGLE IRON REAR PEDESTAL SUPPORT BRACKET TO THE FRAME.

The risk

BOLT HEAD IMPINGMENT CAN CAUSE THE PEDESTAL BOLT RETNETION SYSTEM TO LOSE THE SPECIFIED CLAMP LOAD CAUSING THE CONCRETE DRUM TO SEPARATE FROM THE TRUCK CHASSIS, INCREASING THE RISK OF SERIOUS INJURY OR DEATH.

The fix — what to do

OWNERS HAVE BEEN ADVISED TO IMMEDIATELY CHECK ALL BOLTS ON THE REAR PEDESTALS. IF ANY ONE HORIZONTAL LOCKBOLT IS LOOSE OR MISSING, TO IMMEDIATELY REPLACE THE LOOSE LOCKBOLT. OSHKOSH IS PROVIDING REPLACEMENT KITS WITH INSTRUCTIONS AND HAS AUTHORIZED LABOR REIMBURSEMENT. OWNERS WERE CALLED BEGINNING DECEMBER 10, 2000, TO ADVISE THEM OF THIS PROBLEM. AN OWNER NOTIFICATION LETTER WAS SENT TO EACH CUSTOMER ON DECEMBER 15, 2001, TO CUSTOMERS WHO HAD NOT REPLIED TO THE INITIAL COMMUNICATION. OWNERS SHOULD CONTACT OSHKOSH AT 1-920-235-9151.

ALSO CONTACT THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION'S AUTO SAFETY HOTLINE AT 1-888-DASH-2-DOT (1-888-327-4236).
