Part of the Kubota Repair Manuals.
This Kubota workshop manual covers the RTV-X900 and RTV-X1120D utility vehicles built from 2013 to 2021, running the Kubota D902 and D1105 diesel engines. Across 488 pages it follows the factory service documentation (publication 9Y111-26171), organized system by system.
You get full engine work, the hydrostatic transmission, front and rear axles, brakes, hydraulic power steering, the hydraulic lift system, and complete wiring diagrams for both models. The General section carries product identification, lubricants, and tightening torques, and verified capacities include an 18.0 L hydraulic tank, a 7.0 L transmission case, and a 6.1 L cooling system.
This is the reference owners and independent mechanics need to diagnose, service, and rebuild the RTV-X900 and RTV-X1120D correctly, with the torque values and procedures Kubota specifies.
