This is the Kubota Workshop Manual for the B2630HSD, B3030HSD, and B3030HSDC compact tractors, publication 9Y011-13494. Across 498 pages it documents these three models and their Kubota diesel engines, the D1105 and V1505 series.
You get mechanism descriptions, troubleshooting, servicing specifications, and tightening torques for the engine, transmission, front and rear axles, brakes, power steering, the hydraulic system, the electrical system with wiring diagrams, and the cab with its air conditioning. Fluid capacities, valve clearances, and torque values are given with page references.
This is the reference an owner or independent mechanic needs to chase hard steering, a shutdown with clicking, or weak hydraulics after winter storage, and to carry out the repair with factory procedures rather than booking dealer time.
