Additional Notes

  • The Terex PPM AC55 mobile truck crane carries an 18-liter tank capacity for the hydraulic steering system, which represents the total fluid volume held in the reservoir rather than a full system overhaul fill.
  • A 2000-hour change interval applies to the AC55 hydraulic steering system under normal use conditions, a figure typical of heavy equipment operating on structured maintenance schedules tied to machine hours rather than calendar time.
  • The AC55 hydraulic steering system also accommodates biodegradable oil as an alternative fluid type, with the tank capacity and 2000-hour change interval remaining identical to the conventional fluid specification.
