Part of the Kubota Repair Manuals.
This is the factory Kubota workshop manual for the KH series compact excavators, covering the KH-36, KH-41, KH-51, KH-66, KH-91, KH-101, KH-151, and KH-191. Across 334 pages it documents the whole machine in five sections: general service data, the machine body and undercarriage, the hydraulic system, the electrical system, and the diesel engines (Z620-KW, D950-BH1, D950-BH2, D1402-BH4, V1902-BH3, and V1902-BH4).
Inside you get troubleshooting charts, specifications, tightening torque values, and step by step disassembly and reassembly procedures for the front attachment, swivel reduction gear, travel gear, pumps, control and relief valves, cylinders, motors, and full circuit diagrams. Whether you are rebuilding a tired hydraulic pump, servicing worn track rollers, or chasing a starting fault, this PDF puts the same reference Kubota technicians rely on on your bench.
