Service bulletin SIL 841
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 on certain derricks built from 2008 to 2020 the diameter of the wire winch rope installed may exceed the maximum allowable diameter specified by the ANSI A10.31 derrick standard based on the winch drum diameter. Use of an oversized wire winch rope can lead to improper rope spooling on the winch drum and premature rope wear.
