Written for both the 210 X2 and 240 X2 hydraulic excavators, this 550-page Link-Belt 210 X2, 240 X2 shop manual PDF runs from engine consumables through the undercarriage, swing body, pump and valves, attachment and cab. Roughly a third of the book goes to the lower mechanism: travel motor removal and full teardown, plus take-up, carrier and track roller rebuilds. Where the two models part ways, the swing motor and swing reduction gear get separate disassembly procedures for each, while hydraulic schematics and a regulator operation section show how the pump answers your pilot control circuit. Hold travel motor drain pressure to 0.2 MPa in normal use, and torque the relief valve assembly to 373 ± 20 N•m when it goes back in. Guess that figure and you pay for a second teardown. Bookmarked, text-searchable pages put the right procedure in front of you quickly, so your excavator is digging again by the next shift.
