FL938 – Steering Gear Incorrectly Assembled – 2021-2022 Freightliner (FCCC) MT45, 2022-2023 Western Star 4900 & Freightliner Cascadia

12. Remove the steering gear.

NOTICE

The head side of bolts needs to be inboard, inside the rail flange.

13. Install the washer (23-09114-004) on the new bolt (23-11757-350), then install the bolts into the three holes
in the rail.

14. Install the new steering gear (RHS MD83PB3Y) on the bolts in the rail. Install the washer (23-09114-004) first, and then install the nut (23-13833-112). Tighten the fasteners hand tight.

15. Use a 1-1/8 inch socket and wrench to tighten the fasteners that attach the steering gear to the rail. Tighten the fasteners 221 lbf·ft (300 N·m).

16. Install the hydraulic hose fittings in the gear, oriented as shown in Fig. 8. Tighten the hose fittings 45 lbf·ft (61 N·m).

17. Install the hose on the fittings, and tighten them hand tight.

18. While holding the small part of the fittings using a 3/4-inch wrench, use a 7/8-inch wrench to tighten the hose fittings. Tighten the hose fittings 45 lbf·ft (61 N·m).

Install the steering linkage on top of the gear. See Fig. 10.

Box 4090 Portland, OR 97208-4090 800.547.0712 Phone Daimler Trucks North America LLC Juillet 2022 FL938 Avis de rappel intermédiaire Transports Canada nº 2022-300 Objet : Boîtier de direction Bendix Le présent avis vous est envoyé conformément aux exigences de la Loi sur la sécurité automobile. La présente a pour but de vous informer que votre véhicule est susceptible d’avoir un défaut qui pourrait porter atteinte à la sécurité humaine. Au nom de sa division Freightliner Trucks Division et de sa filiale en propriété exclusive Freightliner Trucks Division, Daimler Truck North America LLC (DTNA) a déterminé qu’une défectuosité liée à la sécurité des véhicules à moteur existe sur certains véhicules Freightliner Cascadia et Freightliner Custom Chassis modèles MT45 et MT45G des années modèles 2022 à 2023 équipés d’un boîtier de direction Bendix. Sur certains véhicules, un nombre insuffisant de billes circulantes dans le boîtier de direction pourrait provoquer une torsion du roulement lorsque des charges sont appliquées. Dans certains cas, les billes peuvent s’aligner du même côté de l’arbre de vis sans fin du roulement et des charges concentrées peuvent provoquer la rupture des pièces internes du roulement, entraînant une perte de direction, ce qui pourrait augmenter le risque d’accident. Ceci est le premier de deux avis que vous recevrez à ce sujet. Le but de cette lettre est de vous informer d’un rappel à venir pour corriger le problème mentionné ci-dessus. Daimler Trucks prépare actuellement la fourniture des pièces de remplacement. Aucune action n’est nécessaire pour l’instant. Le deuxième avis vous informera quand la solution définitive pour y remédier sera disponible. Lorsque vous recevez le deuxième avis, veuillez communiquer avec votre concessionnaire autorisé Daimler Trucks North America, afin de prendre les dispositions nécessaires pour le rappel de votre véhicule. Si vous n’êtes pas le propriétaire du ou des véhicules dont les numéros d’identification apparaissent sur l’avis de rappel, veuillez retourner l’avis au Service des campagnes de garanties avec tous les renseignements dont vous disposez qui pourraient nous aider à identifier le propriétaire actuel. Le loueur est également tenu par la loi fédérale de faire parvenir cet avis au locataire dans les 10 jours. Si vous êtes un fabricant secondaire, la loi fédérale exige que vous fassiez suivre cet avis à vos distributeurs et détaillants dans les cinq jours ouvrables. Si vous avez des questions sur cet avis de rappel, veuillez communiquer avec le Service des campagnes de garantie au 1-800-547-0712 de 7 h 00 à 16 h 00, heure du Pacifique, du lundi au vendredi ou par courriel à DTNA.Warranty.Campaigns@Daimlertruck.com.
