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.
CSR-3320
Service Bulletin/Repair Instructions
Altec Industries, Inc. has been notified of a condition affecting certain International HV, HX, eMV, CV, LT, RH, LoneStar, and MV Series trucks equipped with Altec equipment. Outdated Body Control Module (BCM) software may generate erroneous fault codes after the vehicle has been inactive for two to three days.
SIL-3273
Service Bulletin/Repair Instructions
Altec has received notification from Parker Chelsea, the manufacturer, of an issue with some of their 281 and 890 Series PTOs. An unintended restriction in lubrication flow may produce elevated back pressure in cold-start scenarios, leading to partial engagement of the clutch. Once the vehicle reaches normal operating temperature, the clutch drag will abate. In extreme cases, repeated cold starts may result in clutch disk damage and failure to engage when activated.
SIL-3243
Service Bulletin/Repair Instructions
Altec has learned that hydraulic hoses on certain DM-E and DH derricks, built between 2021 and 2025, can come into contact with the cord reel, causing the reel to stick. This can cause the pole guide to become inoperable.
SIL-3209
Service Bulletin/Repair Instructions
Altec has learned that the velocity fuse, part of the HOP plumbing on the lower boom lift cylinder, may close and fail to open due to air in the circuit during normal operation on certain D3000H, DT65H, and DT85H series derricks built from July 2022 to May 2025. This can prevent the hydraulic overload protection system from operating properly to prevent a structural overload of the boom.
SIL-3214
Service Bulletin/Repair Instructions
Altec has learned that the king pin towing capacity placard might not be installed on certain DL derricks built from August 2005 to October 2024. This could lead to unintentional overloading which could result in cracks or deformations to the king pin assembly. Altec has had no reports of this issue occuring. This area should be inspected regularly as outlined in the Welds and Fasteners subsections in Section 4 of the unit’s Maintenance and Parts Manual.
