Part of the Kubota Repair Manuals.
This Kubota Shop Manual covers the D1005-E4B, D1105-E4B, D1305-E4B, and V1505-E4B diesel engines under Kubota publication 9Y111-07840. It gives owners and independent mechanics the factory service information for these engines, from routine maintenance through full disassembly and rebuild.
The 128-page manual is organized into Information, General, Mechanism, and Servicing. You get engine specifications, a complete maintenance check list by service hour, troubleshooting tables, servicing specifications, tightening torques, and the checking, disassembling, and assembling procedures for the engine.
With documented figures such as valve clearance, injection pressure, cylinder head and connecting rod torque, and oil capacity for each model, this PDF lets you work to Kubota specification whether you are adjusting valves, chasing a no-start, or overhauling a high-hour engine.

Kubota D1005-E4B, D1105-E4B, D1305-E4B, V1505-E4B Common Problems This Manual Covers
Hard starting or no start
A Kubota diesel that will not fire often has a fuel delivery fault, air in the lines, or a weak glow system. The troubleshooting tables walk you through the checks in order before you condemn the injection pump.
Manual Section: Servicing p. 59Loss of power under load
Low output usually traces to a clogged fuel filter or nozzle, a dirty air cleaner, or air in the fuel system. The servicing section covers the fuel and injection tests to isolate the cause.
Manual Section: Servicing p. 59Excessive smoke or oil in exhaust
Oil burning and heavy smoke point to worn or chipped piston rings or excessive valve stem clearance. The servicing specifications and allowable limits tell you when a part is out of tolerance.
Manual Section: Servicing p. 59Rough running after overdue filters
Skipped fuel filter changes leave the engine starved and running rough. The maintenance check list gives the service intervals, including the fuel filter element replacement, to keep fuel flow clean.
Manual Section: General p. 18Hard cold starting and weak glow
Cold-start trouble often comes down to failing glow plugs. The servicing section provides the glow plug resistance value so you can test each plug rather than guessing.
Manual Section: Servicing p. 59Fan belt slip and overheating
A loose or worn fan belt lets the alternator and water pump underperform, causing overheating and weak charging. The maintenance section lists the correct belt deflection to set tension properly.
Manual Section: General p. 18Frequently Asked Questions
