On tuesday, july 19 of 2011, I observed that the 5TH wheel bolts on abf unit number 19223 were loose enough to be turned by hand. The bolts are not being interfered with by the huck rivets below them. The nuts are prevailing torque lock nuts and are not loose on the bolts. The bolts have stretched…
On tuesday, july 19 of 2011, I observed that the 5TH wheel bolts on abf unit number 19223 were loose enough to be turned by hand. The bolts are not being interfered with by the huck rivets below them. The nuts are prevailing torque lock nuts and are not loose on the bolts. The bolts have stretched under load. I was going to show the unit to the director of maintenance, who happened to be in our shop that day. Unfortunately, unit 19223 was sent out before I could show him. I did, however, make a video of me turning the loose bolt by hand. This IS only one of hundreds of abf macks from 2009 and 2010 that have 5TH wheel bolts that are yielding under load.

Some of the 2008, many of the 2009, and almost all of the 2010 model mack trucks used by abf freight system were built and delivered with weak bolts holding the 5TH wheel coupler to the frame. on 27 sept 2010, unit 19212 was in the shop for routine repairs. A mechanic noticed that all of the…
Some of the 2008, many of the 2009, and almost all of the 2010 model mack trucks used by abf freight system were built and delivered with weak bolts holding the 5TH wheel coupler to the frame. on 27 sept 2010, unit 19212 was in the shop for routine repairs. A mechanic noticed that all of the bolts on the right side were loose enough to rattle in their holes and that the coupler was sliding around on the frame. The manager instructed us to tighten the bolts and not to replace any unless they stretched. All of the bolts stretched. All were replaced. *Tr

My coworker was changing the oil on a 2009 mack and I happened to notice that the 5TH wheel plate was shifting around on the frame. I applied a box end wrench to the mount bolts and discovered that all ten of the fasteners holding the 5TH wheel to the frame could be turned easily using one hand.…
My coworker was changing the oil on a 2009 mack and I happened to notice that the 5TH wheel plate was shifting around on the frame. I applied a box end wrench to the mount bolts and discovered that all ten of the fasteners holding the 5TH wheel to the frame could be turned easily using one hand. That IS not my idea of being securely attached! No action was taken on this truck because it was time to go home and if the boss doesn't care and mack doesn't care what can I do except complain to the federal government that mack IS using substandard bolts in the assembly of their trucks! the 5TH wheels are loose. management doesn't want to know! be very afraid on the highways my fellow americans, you are more likely to die from a truck accident than you are from a terrorist attack! *Tr
Defect investigations
NHTSA’s Office of Defects Investigation opened these reviews into vehicles including this one.
- Failing 5th wheel attachment bolts
On October 3rd 2010 the Office of Defects Investigation (ODI) received two complaints on 2009 - 2010 Mack CXU612 and CXU trucks for failing bolts that clamp the 5th wheel to the frame of the truck. On January 19, 2011 ODI opened this Preliminary Evaluation.During the course of the investigation ODI took possession of…
On October 3rd 2010 the Office of Defects Investigation (ODI) received two complaints on 2009 - 2010 Mack CXU612 and CXU trucks for failing bolts that clamp the 5th wheel to the frame of the truck. On January 19, 2011 ODI opened this Preliminary Evaluation.During the course of the investigation ODI took possession of fasteners from the field.These fasteners, taken off subject complaint vehicles, exhibited 'hourglass like stretching' indicating plastic deformation.This same source supplied ODI with new fasteners (for the subject vehicle) that were recently purchased and never used.The bolts supplied by the manufacturer are M16 x 2 Class 10.9 bolts.Per SAE J1199, these bolts should have a proof load 130 kN (~29,000 lbf) and tensile strength of 163 kN (~36,600 lbf).These bolts are not designed to be torque to yield.ODI took possession of these field samples and sent them to (VRTC) Vehicle Research and Testing Center for testing.Some of the new and used fasteners from the field were tested to the SAE J1199 standard and all passed.Other tests at VRTC indicated that the stretched bolts were likely the result of over torque during installation or maintenance.VRTC tested other methods to pre-tension the bolts and found that load indicating washers and turn-of-the-nut method both gave better clamping load control than a torque wrench.In February 2011 Mack started to perform field inspections associated with this investigation in an attempt to understand the cause of the bolt failures.During these inspections, Mack discovered that there was an interference with the bolts used to secure the fifth wheel to the frame.This interference can prevent the bolts from being torqued to specification.If this occurs, the bolt(s) may fail and in extreme cases may result in the fifth wheel coming loose causing the trainer to separate from the tractor.Mack has issued a voluntary Safety Recall 11V-209 for (failure of fifth wheel mounting bolts). However, claims in the field suggest the manufactured supplied fasteners are inferior and stretch regardless of interference.ODI will continue to monitor this issue and follow the completion progress.If failures continue, ODI may open another investigation to investigate future failures.Mack Truck's recall action resolves the issues raised by this investigation and, therefore, this investigation is closed.
