Part of the Case Repair Manuals.
Looking for a Case CX290B repair manual PDF you can actually trust? This 488-page factory book (OEM #87637610 NA) covers the complete crawler excavator, from engine and pump control through swing, travel, boom, arm, and bucket hydraulics. Inside: full electric circuit diagrams with connector wiring layouts, large fold-out hydraulic and electrical schematics, and step-by-step pressure measurement, adjustment, and air bleed procedures. You also get error code lists, troubleshooting charts that run all the way to the air conditioning system, and torque data for standard and special fasteners. Set the main relief pressure to 34.3 MPa, and fit a true 6 micron return filter instead of whatever the parts counter hands you. Chasing an electrical fault without a diagram is a long afternoon. Bookmarked and keyword-searchable; pull the schematic up on your tablet at the machine and get back to digging.
