Three common-rail variants, one OEM source: this Workshop Manual (OEM #9Y111-06740) runs 210 pages on returning the V2607-CR-E4B, V2607-CR-TE4B, and V3307-CR-TE4B Tier 4 engines to factory spec. Factory wiring diagrams cover the ECU harness, the injector harness, and full system routing; hydraulic schematics map the common rail fuel circuit. The maintenance schedule runs in tiers, from the first 50-hour service out to the 3,000-hour interval. Fifty pages walk teardown and reassembly of the cylinder head, gear train, piston, EGR system, supply pump, rail, and injectors, backed by troubleshooting charts for the Engine Control System and aftertreatment devices. Torque the oil drain plug to 45-53 N·m, and confirm 10.2L in a V2607 or 11.2L in the V3307 before startup. Bookmarked sections drop you straight onto the procedure.

Kubota V2607-CR-E4B, V2607-CR-TE4B, V3307-CR-TE4B Common Problems This Manual Covers
Kubota V2607-CR-E4B cranks normally but won't fire, no fuel reaching injection lines
Check the fuel filter and replace it if it has exceeded 500 hours of service (page 32). Bleed air from the supply pump inlet and inspect fuel hoses for kinks. If flow is absent at the injection line, suspect a failed supply pump. Retorque any disturbed injection pipe nuts to 30 to 40 N·m (page 123) after line work.
Manual Section: Engine No-StartHard start in cold weather, engine cranks but won't fire without extended cranking
Test each glow plug for resistance: a healthy plug reads approximately 0.95 Ω. Replace any reading open circuit or significantly higher. Torque new plugs to 7.7 to 9.3 N·m (page 123). Also test battery voltage under cranking load; a discharged battery won't spin fast enough to fire even with perfectly functional glow plugs.
Manual Section: Engine No-StartHeavy black or dark gray exhaust smoke under load, power feels noticeably flat
Remove and inspect the air cleaner element; a clogged filter is the most common cause of black smoke on these engines. If the air path is clear, verify fuel grade against the specifications on page 9 and check for an overloaded condition. A defective injector or blocked DPF filter comp will also cause black exhaust; work through each cause before pulling injectors.
Manual Section: Exhaust Gas Black or Dark GrayOil pressure warning illuminates at idle, oil level is confirmed full and correct grade
Verify oil capacity for your engine: 10.2 L (2.69 U.S.gals) for V2607 variants or 11.2 L (2.96 U.S.gals) for the V3307 (page 9). If level is correct and idle pressure stays below 50 kPa (7 psi) (page 120), shut down immediately. Inspect the oil strainer for sludge and test the relief valve for sticking before assuming internal bearing wear.
Manual Section: Oil Pressure LowEngine temperature climbs into the red zone after 30 minutes of normal operation
Measure fan belt tension: spec is 10 to 12 mm deflection at 98 N (22 lbf) applied load (page 121). A slack belt won't drive the water pump at full speed. Inspect radiator fins for debris blockage, verify coolant level is adequate, and test the radiator cap seal. If all those pass, suspect a blocked coolant passage or failing head gasket.
Manual Section: Engine OverheatedRough idle and erratic RPM, engine surges under no load at low speed
Inspect the air cleaner element and replace the fuel filter cartridge at the 500-hour interval (page 32). Check cold valve clearance; spec is 0.13 to 0.17 mm (0.0052 to 0.0066 in.) (page 115). Worn injectors and a sticking supply pump both produce surging; work through the troubleshooting procedures before pulling any injectors.
Manual Section: Engine Revolution Not SmoothFrequently Asked Questions
What are the recommended service intervals?
The maintenance check list groups tasks by interval. Daily items include engine oil, fuel, and coolant level checks. Engine oil changes and oil filter cartridge replacement fall at every 500 hours or 1 year, whichever comes first. Fuel hoses and clamps get replaced every 2 years.
What fluids and capacities does this machine require?
Run Diesel Fuel No. 2-D S15 with Class CJ-4 oil per API classification. Oil capacity is 10.2 L (2.69 U.S.gals) on the V2607-CR-E4B and V2607-CR-TE4B, and 11.2 L (2.96 U.S.gals) on the V3307-CR-TE4B. The cooling system uses a pressurized radiator and forced circulation via the water pump, filled with clean, soft water and anti-freeze (L.L.C.).
How to troubleshoot engine won't start?
No-start traces back to a few common causes: no fuel, or air or water in the fuel system. Fixes are filling the tank, bleeding the air, or changing/repairing the fuel system (page G-14). A defective fuel pump (replace, page 1-S48) or a clogged injector (replace, page G-20, 1-S41) can also be at fault.
What torque specifications are listed?
General torques cover screws, bolts, and nuts: M6 (7.9 to 9.3 N·m), M8 (18 to 20 N·m), M10 (40 to 45 N·m), and M12 (63 to 72 N·m). Component-specific values are listed too, including glow plugs (7.7 to 9.3 N·m) and injection pipe retaining nuts (30 to 40 N·m).
