2000–2004 Mac Trailer recall: equipment

⚠️ What's wrong

On certain frame and frameless dump trailers, the 8-INCH five stage telescopic cylinder commonly referred to as a "super dump", with use the packing nut on the fourth stage retaining the plunger CAN loosen, backing off the fourth stage. This condition, if not remedied, CAN continue until the packing nut backs completely off the stage. If this occurs, there is nothing to retain the fifth stage (plunger) in the assembly.

💥 The risk

When the cylinder is extended to its maximum stroke, the fifth stage CAN separate from the cylinder assembly causing loss of control over the Trailer, allowing the Trailer to free fall, possibly causing serious injury or death.

🔧 The fix

Parker hannifin will provide a field modification kit #375 1805 206 to secure the packing nut in position free of charge. Owners who do not receive the free remedy within a reasonable time should contact parker hannifin at 1-888-231-7461 or mac Trailer at 330-823-9190.
