## 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.
