ON CERTAIN DUMP TRAILERS EQUIPPED WITH SEALCO SPRING BRAKE CONTROL VALVE ASSEMBLIES INCORPORATED IN ARVINMERITOR AXLES, PART NOS. 110700 AND 110800, THERE IS A RECESSED AREA ON TOP OF THE VALVE IN WHICH A BRASS GUIDE PIN FITS DOWN INSIDE THE BODY OF THE VALVE AND IS HELD IN PLACE BY A STEEL SNAP RING. THE RECESSED AREA ALLOWS ACCUMULATION OF WATER, DIRT, AND/OR CHEMICALS TO BUILD UP BEHIND THE SNAP RING TO THE POINT WHERE IT WILL NO LONGER CONTAIN THE GUIDE PIN RESULTING IN A FAILURE OF THE AIR VALVE.
FAILURE OF THE VALVE IN AN EMPTY OR LIGHTLY LOADED TRAILER WHILE THE VEHICLE IS IN MOTION COULD RESULT IN A HARD APPLICATION OF THE SPRING BRAKES, POSSIBLY LOCKING UP THE TRAILER WHEELS AND RESULTING IN A VEHICLE CRASH.
DEALERS WILL INSTALL THE BRAKE VALVE. OWNER NOTIFICATION BEGAN APRIL 25, 2004. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT HALE AT 610-395-7868 OR SEALCO AT 602-253-1007.
