OTTAWA, Ont. — Transport Canada has issued four separate recall notices regarding trailers impacting 12,989 units in service today.
The largest number of wagons involved are Trailmobile O models manufactured between 2000 and 2003. The federal watchdog says 9,345 of these trailers are equipped with Sealco spring brake control valves (part number 110800, manufactured between Sept. 1, 1997 and Apr. 1 2000).
These valves are subject to a corrosion failure of the snap ring, which then interferes with the guide pin. Such a failure will cause an unintentional, potentially catastrophic application of the spring brakes. To address the problem, Sealco will provide a prevention kit to impacted fleets.
As well, some 2,747 units made by Lode King Industries have been saddled with the same problem. If you’re currently running 1999-2000 Lode King platform trailers, grain trailers, step deck trailers or container chassis — be prepared to do a little extra preventive maintenance very soon.
The same problem has also forced notices to go to the owners of 409 Arne’s Trailers manufactured by Arne’s Welding between 1999 and 2000.
In a completely unrelated notice, Transport Canada’s recall department is also issuing warning about 488 Manac-made semi-trailer built between 2000 and 2001.
Certain trailers manufactured between August 2000 and May 2001 and equipped with Bendix SR-2, SR-4 or SR-5 trailer spring brake valves are the units in question.
The molded rubber face of the inlet/exhaust valve (I/E valve) can separate from the valve’s metal insert. Air can be trapped causing the rubber to balloon and block the exhaust passage of the trailer spring brake circuit. This condition can result in the affected vehicles being unable to apply the trailer parking/emergency spring brakes in the event of a trailer supply line failure.
Unintended rollaway could occur, possibly resulting in personal injury or death to the vehicle occupant or any bystanders. The fix is simple enough — Bendix says it will supply customers with a repair kit and a labor allowance.
