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 3041
Altec has learned that when the coolant-style oil heater on certain AH75B/85B100B aerial devices built from April 2021 to August 2022 is active, the operator has to turn off the engine in order to disengage the power take-off (PTO). Replacement of a wiring harness in the pedestal is required to resolve this issue.
SIL-3026
Altec has learned that certain DRM 12 and DRM 12he chippers built from 2014 to 2022 could develop fatigue cracks in the upper pivot housing weldment. If not addressed, these cracks can lead to damage of the chipper. The customer should inspect the upper pivot housing weldment on the affected chippers. Complete this no later than 30 days from the receipt of the notice.
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.
