Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
SIL-3203
Altec has learned that there could be a missing spacer on the Huckbolt installed on the curb side shear plate on certain AT37 and AT41 aerial units. This could cause premature wear on the bolt and shear plate and increase the risk of damage to the frame rail.
PUN-3183
Altec has developed an optional latch guard for certain AT37/41/48-M/ME/P/PE/S/SE, including JEMS, aerial devices built from October 2018 to May 2024 with a custom option for automatic lower boom rest. This guard provides additional clearance between the moving portion of the automatic boom latch and the operator.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
