Part of the Kubota Repair Manuals.
This is the factory Kubota Workshop Manual for the RTV1100 utility vehicle, a 521-page service document (publication 9Y121-00111) built around the D1105-E2-UV and D1105-E3-UV diesel engines. It also covers the RTV1100C and includes a dedicated New RTV1100 section at the back.
The manual is split into General, Mechanism, and Servicing, with full chapters for the Engine, Transmission, Rear Axle, Brakes, Front Axle, Steering, Hydraulic System, Electrical System, and the air conditioning covered under Others. Each section carries servicing specifications, tightening torques, and disassembly and assembly steps.
With it an owner or independent shop can rebuild the hydrostatic transmission, set steering and hydraulic relief pressures, service the cab air conditioner, and trace any electrical circuit from the wiring diagram. It is a searchable PDF download with a text layer, ready for a laptop, tablet, or phone in the workshop.

Kubota RTV1100 Common Problems This Manual Covers
HST transmission weak or noisy
As an RTV1100 accumulates hours the hydrostatic transmission can lose drive, creep, or whine. The Transmission section covers the hydrostatic unit, range gear shift and front wheel drive sections, transmission case, and differential so you can check wear and function.
Manual Section: 2 Transmission p. 138Cargo bed hydraulics slow or weak
A bed that lifts slowly or will not hold points to the hydraulic pump, control valve, or relief valve setting. The Hydraulic System section covers the circuit, pump, cylinder, control valve, and relief valve setting pressure.
Manual Section: 7 Hydraulic System p. 305Heavy or wandering steering
Hard steering or poor return traces to the steering controller, cylinder, or relief valve. The Steering section gives the hydraulic circuit, controller, cylinder, pump, and the relief valve operating pressure for correct setup.
Manual Section: 6 Steering p. 284Engine overheating or hard start
Overheating or hard starting on the D1105 engine points to the cooling or fuel system. The Engine section covers the engine body, lubricating, cooling, and fuel systems plus the cylinder head and valve with servicing specifications.
Manual Section: 1 Engine p. 80No start or dead battery
A no crank or no charge condition is usually in the starting or charging circuit rather than the engine. The Electrical System section carries the wiring diagram, starting system, charging system, and gauges for step by step diagnosis.
Manual Section: 8 Electrical System p. 325Air conditioning not cooling
Poor cab cooling points to the compressor, condenser, receiver, or magnet clutch. The Others section covers the compressor, condenser, receiver, air conditioner unit, and system control, including the magnet clutch air gap spec.
Manual Section: 9 Others p. 384Frequently Asked Questions
