Service bulletin SIL 805

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 certain TS20-4P units built from 2019 to 2021 have fairlead rollers that do not consistently rotate freely. This operation can cause damage to the ropes. Altec requires that the levelwind fairleads be replaced within 60 days of receiving this notice.
