Part of the Case Repair Manuals.
Need the factory service data for your Case CK25 or CK28? This 288-page Crawler Excavator Service Manual (OEM #Lep 7-37912GB) walks through every system on both machines, from engine tear-down to upperstructure hydraulics. Inside: wiring schematics for the alternator and starter circuits, hydraulic schematics covering the main pump, swing motor, and full pilot circuit, and a dedicated troubleshooting section for chasing electrical and hydraulic faults. Torque tables run across every assembly. Fill the CK25 engine with 4 litres of oil (5.3 for the CK28) and torque M10 Grade 7 fasteners to 48.0-55.9 Nm before you close anything up. Your machine is down. Get the factory number on the first try, not a forum guess. Opens on any device; bookmarked for instant section jumps.
