Roadmaster recalls certain Blackhawk All Terrain, Falcon 2, Falcon All Terrain, Falcon 3HD, Liberty, Sterling, and Nighthawk tow bars. The tow bar may detach due to a loose roll pin in the T-Bolt assembly.
>In tow bars subject to this notice, the T-bolt (See Figure 1) assembly consists of a large bolt and nut secured by a roll pin. Not all tow bars, even of the same model, have a roll pin and roll pin hole. If the roll pin is missing, damaged, or partially backed out of its hole (more than 1/16 inch above the hole), vibration and repeated loading may allow the T-bolt to disassemble. This could result in separation of the tow bar from the hitch receiver, potentially causing the towed vehicle to separate from the motorhome and increasing the risk of crash.
The condition addressed by this recall develops gradually and can be identified through visual inspection. The roll pin does not become dislodged suddenly. Rather, if affected, the roll pin may slowly migrate from its installed position over many hundreds or thousands of miles of towing due to vibration and repeated loading.
