Printed under Link-Belt Book No. 9-44510LX, this 610-page Link-Belt 290 LX shop manual PDF is the factory text for the 290 LX crawler excavator, organized in nine sections from general data and standard torques through the upperstructure. Upperstructure hydraulics fill well over a third of the book: removal and teardown of the main and pilot pumps, main control valve, swing motor, hydraulic swivel and attachment cylinders, plus the pressure settings you verify before condemning a component. Large-format hydraulic and electrical schematics trace each circuit, while undercarriage and drive train chapters cover track removal, idler service, and travel and swing reduction gear rebuilds. Refill the hydraulic reservoir with 31.7 gallons (63.4 for the full circuit) and torque the travel motor and reduction gear assembly to 664 to 774 lb-ft. Out on site, nobody else is there to ask. Bookmarked and text-searchable, it lets you confirm which assembly you're replacing before ordering, so the part is right the first time.
