NCAP overall
3 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
CLAMP WHICH SECURES THE FUEL FILLER HOSE TO THE BODY IS MISSING.
Consequence
HOSE COULD SAG ONTO REAR SPRING WEARING A HOLE IN THEHOSE; THIS COULD ALLOW FUEL TO SPILL ONTO GROUND WHILE FILLING OR DRIVINGTRUCK.
Remedy
INSTALL MISSING CLAMP AND REPLACE FILLER HOSE IF IT HAS BEEN RUBBED BY SPRING.
Defect
THE REINFORCING PLATES WERE OMITTED FROM THE TRAILER PIN BOX ASSEMBLY, WHICH IS USED TO HOLD THE FIFTH WHEEL ASSEMBLY TO THE TRAILER. CONSEQUENCE OF DEFECT: A FATIQUE FAILURE OFF THE PIN BOX ALLOW THE FIFTH WHEEL ASSEMBLY TO SEPARATE FROM THE TRAILER. THEREFORE, THE TRAILER WILL FALL OFF THE TOWING TRUCK AND ROLL UNCONTROLLED ON THE ROADWAY. THIS MAY CAUSE AN ACCIDENT.
Remedy
REPLACE THE PIN BOX ASSEMBLY IF REINFORCEMENT PLATES ARE MISSING.
Defect
THE ROUTING OF BRAKE LINES BROUGHT THE LINE CLOSE TO AN AREA USED TO FASTEN THE SEAT SOCKET SUPPORT STRUCTURE TO THE CHASSIS. THE FASTENING OF SEAT SUPPORT IS DONE WITH BOLTS AND WHEN THE BOLTS ARE TIGHTENED THE FREE END OF THE BOLTS PINCHES ONE OF THE BRAKE LINES AGAINST THE CHASSIS FRAME RAIL. THIS CAUSES A REDUCTION IN THE BRAKE LINE WHICH REDUCES THE VOLUME OF FLUID PASSING THROUGH THE LINE. CONSEQUENCE OF DEFECT: THE REDUCED VOLUME OF FLUID AFFECTS THE EFFICIENCY OF THE BRAKE SYSTEM. ALSO THE BRAKE LINE MAY CRACK CAUSING LOSS OF FLUID LINE . IN EITHER CASE, A LONGER STOPPING DISTANCE WOULD BE REQUIRED WHEN MAXIMUM BRAKE EFFICIENCY IS NEEDED. OPERATION OF A VEHICLE WITH DAMAGED BRAKES COULD LEAD TO A VEHICLE CRASH.
Remedy
INSPECT AND REPLACE THE AFFECTED BRAKE LINE WITH A NEW PART.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 3 recalls should be verified as completed.
Yes — NHTSA lists 3 recall campaigns affecting the 1983 Grumman Kurbmaster. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
