Service bulletin Upgrade_Letter

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

This field service bulletin informs vehicle owners and aftermarket part purchasers that Gillig will be sending them parts and service instructions to upgrade the electric power steering pump systems on certain BAE Hybrid Low Floor buses. The bulletin details how a new pump-motor "swing unit" will be provided so that fleets can iteratively upgrade one bus at a time by replacing and shipping the existing unit (and units in parts inventory) to an Eaton-authorized service center for upgrade.
