Quick answer

Altec has learned that output drive sleeve on certain HD35A pressure diggers built from May 2020 to January 2021 may fail suddenly during use, generating a large quantity of debris in the auger transmission gearbox. If the unit is not shut down immediately, if this failure occurs, this debris can contaminate other components throughout the hydraulic system, causing major additional damage. The customer should contact Altec Shop Service within 30 days of receiving this notice to schedule the output drive sleeve to be replaced as soon as this can be performed at an Altec facility. While awaiting the repair, advise all unit operators that if they hear any loud grinding or other unusual noises from the auger transmission gearbox or notice the kelly bar has suddenly started drifting, they must stow the unit immediately and take it out of service.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
