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-3160
Altec has learned that the pole setter boss was not welded to specification on certain HD35A-22 units built from September 2008 to April 2024. This can lead to cracks in the pole setter tube outer weldment.
SIL 3077
Altec has learned that the Samlex inverter default threshold on certain units built from August 2022 to April 2023 may not be able to accommodate the 110 power accessories at the platform. This can result in the operator being unable to use the accessories during normal operation until the inverter charges the battery above the threshold.
SIL 3039
Altec has learned that the hydraulic ball valve on the hydraulic reservoir return line of HD35A pressure diggers built from September 2014 to November 2022 may not get returned to the open position after being turned to the closed position for maintenance. If the unit is started while the ball valve is in the closed position, the ball valve may become over pressurized and separate, emptying the hydraulic system.
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.
