Part of the Case Operator Manuals.
This 674-page Case WX210, WX240 Hydraulic Excavator Service Manual (OEM #9-91270) puts the complete PCS pump control system, CAN bus electronics, and drive unit rebuild procedures in your hands. Open it up and you get full electrical circuit diagrams down to individual connector pin assignments (X33A through X33P), hydraulic schematics covering every cylinder circuit from boom regeneration to slewing and grab rotation, and a fault code section for both the PCS unit and central unit. It's grounded in real numbers too: the coolant temperature sensor torques to 20-30 Nm on a ½-inch x 14 PTF thread, and the B10.1 speed sensor coil should read 450 Ω ± 20 Ω at 20°C. No more chasing an intermittent CAN fault with a test light and hope. Bookmarked by section so you jump straight from wiring to hydraulics to repair instructions, then pull it up on your tablet and get back under the machine.
