Part of the Kubota Repair Manuals.
OEM #9Y111-01039. This 217-page workshop manual PDF covers all four Kubota variants: V2607-DI-E3B, V2607-DI-T-E3B, V3007-DI-T-E3B, and V3307-DI-T-E3B. Detailed disassembly and assembly procedures walk through the cylinder head, crankshaft, pistons, injection pump, and turbocharger. Exploded-view diagrams sit alongside tightening torque tables for both general and special-use fasteners, a troubleshooting section, servicing clearances, and the full maintenance checklist (daily checks through every 3000 hours). Cylinder head mounting screws torque to 147 to 156 N·m; first-stage injection pressure should read 18.64 to 19.61 MPa on the V3007 and V3307 variants. Oil capacity differs by model: 10.2 L for the V2607 engines, 11.2 L for the V3007 and V3307. Multi-level bookmarks let you jump to any system on a tablet or phone at the bench.

Kubota V2607–V3307 Series Common Problems This Manual Covers
Kubota V2607-DI-E3B hard starting, rough running, and heavy black smoke with injector misfire
Perform a leak-back test on each injector before condemning the pump. Replace any nozzle that fails its spray pattern check, then torque the nozzle holder clamp screws to 24 to 27 N·m (page 122). Confirm cylinder compression reaches 3.92 MPa at 250 rpm per page 108 before reassembly.
Manual Section: Fuel System Checks p. 108Diesel particulate filter plugging with frequent regens and soot loading warnings under light load
Inspect upstream for overfueling first: a dripping injector dumps raw fuel into the exhaust and loads the filter fast. Verify each injector spray pattern, swap the fuel filter cartridge on the 500 hour interval shown on page 25, and check the air cleaner for restriction. Address the injector fault before cleaning or replacing the DPF.
Manual Section: Abnormal Exhaust Smoke p. 25Coolant mixing into the engine oil with coolant loss and milky residue on the dipstick
Pressure-test the cooling system, then pull the head once coolant intrusion is confirmed. Replace the head gasket and torque the head screws in three stages following the tightening sequence on page 152. Reset valve clearance to 0.13 to 0.17 mm with the engine cold afterward, as shown on page 37.
Manual Section: Engine Overheating p. 37Hard starting in cold weather with weak crank and white smoke before the engine catches
Measure glow plug resistance with a meter; each should read about 0.95 Ω per page 120. Replace any plug reading open. Verify battery voltage and clean the terminals, then set fan belt deflection to 10.0 to 12.0 mm so the alternator holds charge. Confirm fuel reaches the injection pump with no air in the lines.
Manual Section: Engine Starting Issues p. 120Low oil pressure warning at idle with bearing knock once the engine warms up
Verify the oil level and correct SAE grade before anything else; aerated or diluted oil drops pressure fast. Top up (10.2 L capacity on V2607 models, 11.2 L on V3007/V3307), run the engine, and recheck pressure. If it stays low, inspect the oil pump and relief valve for wear. Maintain the 500 hour oil change interval per page 25.
Manual Section: Lubrication System Problems p. 25Frequently Asked Questions
What are the replacement specifications for fuel injectors?
On V2607-DI-E3B and V2607-DI-T-E3B engines, first-stage injection pressure is 18.64 to 20.10 MPa (2703 to 2915 psi). The V3007-DI-T-E3B and V3307-DI-T-E3B spec is 18.64 to 19.61 MPa (2703 to 2844 psi). Valve seat tightness requires no fuel leak at 16.67 MPa (2418 psi). If readings fall outside these ranges, replace or repair the injection nozzle assembly. p. 133
What are the replacement specifications for fuel filter elements?
Intervals depend on filter type. Cartridge-type fuel filters get replaced every 500 hours. Element-type filters should be cleaned every 250 hours. The manual specifies cleaning only for the element type, not a replacement interval. p. 25
What is the cylinder head bolt torque for Kubota V2607 engines?
On V2607-DI-E3B and V2607-DI-T-E3B engines, cylinder head mounting screws torque to 147 to 156 N·m (page 123). The nozzle holder clamp screws torque to 24 to 27 N·m on all variants (page 122). p. 123
What is the engine oil capacity and oil change interval for these Kubota engines?
Oil capacity is 10.2 L (2.69 U.S.gals) for V2607-DI-E3B and V2607-DI-T-E3B engines (page 8), and 11.2 L for V3007-DI-T-E3B and V3307-DI-T-E3B (page 29). Change the oil at 50 hours initially, then every 500 hours (page 25). p. 8
What format is this manual in?
It's a 217-page searchable PDF, available for immediate download. Open it on any device, phone, tablet, or laptop. No shipping, no waiting.
Am I able to print pages from this manual?
