Part of the JCB Repair Manuals.
When your compact excavator goes down, this 453-page JCB 8025ZTS, 8026CTS, JS30, 8029CTS, 8030ZTS, 8035ZTS service manual PDF (OEM #9803/9410-08) gives you the factory procedures to tear down and rebuild the machines. You get complete hydraulic schematics tracing fluid through the control valve, detailed electrical circuits with full harness routing data, and step-by-step fault finding for the servo hand controllers. Open to the engine section to find exact valve clearances and firing orders, or jump into the track and running gear teardowns. Lock down the track gearbox mounting bolts at exactly 98 Nm, then confirm your 1/4-inch BSP adaptors are tightened to 18.0 Nm before testing the hydraulics. Stop wasting shop hours trying to guess pump pressures. Grab this digital download, pull it up on your tablet right next to the undercarriage, and get the job done right.
