Defect SummaryThe splined steering shaft may not be sufficiently engaged as designed due to inaccurate drilling of the holes in the frame to which the cab front mount member is bolted. under certain conditions the steering shaft may disengage. consequence of defect: a jarring impact might cause disengament of the splined shaft resulting in loss of steering control and possibly an accident.
Consequence Summary
Corrective SummaryReplace shafts which measure under the minimum engagement dimensions with longer shaft.
NotesSystem: steering shaft. vehicle description: fire trucks.

Defect SummaryThe floorboard opening and the steering column seal bracket may not allow sufficient clearance for the shaft to turn freely in the center of the bracket/seal. the pinch bolt in the column yoke may bind or lock the column against the bracket, allowing little or no wheel return.
Consequence Summary
Corrective SummaryDealer will enlarge the hole in the floorboard to provide clearance for the steering column u-joint pinch bolt. a new bracket and clamp will also be installed without charge to owner.
NotesVehicle description: truck fire chassis equipped with sgp48 steering gear.system: steering; u-joint, floorboard.consequences of defect: if the steering assembly locks in place, loss ofvehicle control, without warning, and an accident could result.

Defect SummaryOn the involved vehicles the floorboard opening and the steering column seal bracket do not have sufficient clearance to allow the shaft to turn freely. this causes the pinch bolt to bind or lock against the seal bracket.
Consequence Summary
Corrective SummaryThe hole in the floorboard will be enlarged to allow sufficient clearance of the steering column u-joint pinch bolt, and a new bracket and lamp will be installed at no charge to owner.
NotesVehicle description: fire fighting equipment chassis equipped with sgp48steering gears.system: steering; steering column shaft u-joint clearances.consequences of defect: there will be little or no wheel return; loss ofsteering control without prior warning could result in an accident.
