Kubota L3240–L5740 Series Common Problems This Manual Covers
Kubota L3240 engine cranks but won't fire, no exhaust smoke on cold start p. 95
Check that the fuel shutoff valve is open, then bleed air from the injection pump; trapped air is the most common cause after running dry. Verify compression is within 3.6 to 4.0 MPa (page 100). If compression checks out, measure valve clearance cold: spec is 0.18 to 0.22 mm. Full no-start diagnosis is in the Engine section at page 95.
Manual Section: EngineHydraulic three-point hitch won't lift under load, arms drop slowly at rest p. 403
Inspect the hydraulic oil filter and replace it if past the 400-hour service interval (page 33). Check that the position control linkage moves freely and isn't binding at any pivot. Verify the relief valve isn't stuck open; low system pressure starves the lift cylinder. Inspect the hydraulic piston O-ring for bypass. Lift system diagnosis starts at page 403.
Manual Section: Hydraulic SystemClutch pedal grabs or drags through full stroke, transmission grinds and won't disengage at stops p. 39
Measure clutch pedal free travel: spec is 20 to 30 mm (page 39). Adjust at the clevis on the clutch rod if out of range. Inspect the friction disc for oil contamination; a rear main seal leak causes drag even at correct pedal height. Check the release bearing for wear. Clutch section starts at page 179.
Manual Section: ClutchTransmission grinds between gears, pops out of third gear on hills p. 207
Check transmission fluid level first; low fluid causes bearing noise and gear skip-out. Fluid change interval is every 400 hours (page 33). Inspect the shift linkage for rust or binding play at the pivot pins; seized pivots force partial gear engagement. Look for worn synchronizer rings or excess gear backlash. Full internal specs are in the Transmission section at page 207.
Manual Section: TransmissionBrake pedal goes to floor, tractor pulls left under hard braking p. 342
Measure brake pedal free travel: spec is 15 to 20 mm (page 39). Unequal adjustment between left and right pedals causes pulling under braking. Inspect the brake disc for wear and the cam plate for warping or rust. If both pedals feel spongy together, check the hydraulic circuit for leaks. Brake adjustment and disassembly are covered at page 342.
Manual Section: BrakesFront wheels shimmy and vibrate above 10 mph, steering wheel shakes at speed p. 358
Check front tire pressure; spec for 7-16, 4PR tires is 180 kPa (page 84). Inspect toe-in and tighten loose tie-rod jam nuts. Grab each front wheel at 9 and 3 o'clock and rock it: excessive play points to worn king pins or hub bearings. On 4WD models, check the propeller shaft for cracks. Front axle service begins at page 358.
Manual Section: Front AxleFrequently Asked Questions
What are the recommended service intervals?
The manual provides a detailed maintenance schedule. For example, engine oil should be changed every 200 hours, and the engine oil filter replaced every 200 hours. Initial 50-hour checks include replacing the engine oil filter and checking wheel bolt torque.
What fluids and capacities does this machine require?
The manual specifies various fluids and their capacities. For the L3240 model, the fuel tank capacity is 44 L (11.6 U.S.gals, 9.68 Imp.gals) using Diesel fuel No. 1 or No. 2-D. The engine crankcase (with filter) requires 5.7 L (6.0 U.S.qts, 5.0 Imp.qts) of API service classification CF or better engine oil.
How to troubleshoot engine won't start?
If the engine does not start, several probable causes and solutions are listed. These include checking for no fuel (replenish fuel, see page G-7), air in the fuel system (bleed, see page G-41), or a clogged fuel pipe (clean). If the injection pipe retaining nut is loose, it should be tightened (see page 1-S46).
What are the hydraulic system specifications?
The hydraulic system specifications include details for both power steering and three-point hitch pumps. For power steering, the delivery at no pressure is above 18.6 L/min. (4.91 U.S.gals/min., 4.09 Imp.gals/min.) for L3240/L3540/L4240/L5740 models. The Check and High Pressure Relief Valve setting pressure is 34.0 to 37.5 MPa (347 to 382 kgf/cm², 4940 to 5430 psi).
