A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

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.
