NHTSA recall 94E015000 · Equipment
Trailer hitches › Fifth wheel assembly
The defect
Two brackets which hold the air reservoir are welded to the sideplate of the non-structural tailframe of the convertor dolly. A fatigue crack can begin in the sideplate and eventually allow the bracket to break, causing the air reservoir to be supported by the remaining bracket. This bracket can crack and eventually break, leaving the reservoir supported by hoses and tubing.
The risk
Without adequate support, the air reservoir will fallfrom the dolly and become a road hazard.
The remedy
A structural lower flange will be welded to the bottom of the tailframe sideplates. The PR-3 pressure protection valve on the air reservoir will be relocated to clear the new flange.
