Bulletin Summary
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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
