This Kubota Workshop Manual covers the U17, U17-3 and U17-3α compact excavators, publication number 97899-61970, built around the D902-BH-1 and D902-E3-BH-2 diesel engines. It is a 740 page manual with a searchable text layer.
The manual is organized into General, Machine Body, Engine, Hydraulic System and Electrical System, each split into a mechanism section that explains how the system works and a service section with troubleshooting, testing, specifications, and disassembly and reassembly steps. It also covers the Kubota Intelligent Control System (KICS) and the digital meter.
With this PDF you can diagnose hydraulic and electrical faults, rebuild the pump or control valve, service the engine, and set up the undercarriage correctly, using the manual's own torque tables and service limits. Download it once and read it on any device, or print the pages you need at the bench.
