Kubota M4900, M5700, M5700HD Common Problems This Manual Covers
Kubota M4900, M5700, and M5700HD rough idle, low power, and loud engine knocking under heavy load. p. 22
Remove the valve cover and measure the cold engine valve clearance. Adjust the clearance to 0.18 to 0.22 mm as shown on page 22. Inspect the feeler gauge for slight drag. Torque the locknuts and replace the gasket before reassembly.
Manual Section: Engine TroubleshootingPTO shaft stops rotating under heavy load or PTO clutch slips during operation. p. 175
Connect a pressure gauge to the test port to measure the PTO clutch valve relief pressure. Verify the reading falls between 2.45 and 2.55 MPa as specified on page 175. Adjust the shims in the relief valve if the pressure is out of spec.
Manual Section: Clutch TroubleshootingCabin air conditioning blows warm air or noisy compressor squeals upon engagement. p. 454
Inspect the air conditioner drive belt for glazing or excessive wear. Press the center of the belt and measure the deflection. Adjust the tensioner bracket on page 454 until the belt tension deflection measures exactly 10 to 12 mm. Replace the belt if frayed.
Manual Section: Cabin Air Conditioning TroubleshootingExcessive or unusual noise from the rear housing and loud clanking while turning. p. 242
Jack up the rear end and inspect the wheel hubs for play. Tighten the rear wheel mounting nuts to 260 to 304 N-m as detailed on page 33. If noise persists, check the rear axle nut torque on page 242 and verify it holds at 539 to 637 N-m.
Manual Section: Rear Axle TroubleshootingTractor gears clash during operation, hard shifting, or clutch drags when depressed. p. 32
Measure the travel distance at the pedal pad. Loosen the locknut on the clutch rod and turn the turnbuckle to set the clutch pedal free play to 35 to 45 mm. Secure the locknut and test shift engagement per the procedure on page 32.
Manual Section: Clutch TroubleshootingFrequently Asked Questions
What are the recommended service intervals?
The manual provides a detailed service interval table for various components. For instance, engine oil should be changed initially at 50 hours and then every 200 hours. The hydraulic oil filter should be replaced every 200 hours, and the fan belt tension should be adjusted every 200 hours. Daily checks include tire pressure, fluid levels, and brake function.
What fluids and capacities does this machine require?
The machine requires Diesel fuel No.1 or No.2, with a capacity of 65 L (17.2 U.S. gals). The engine crankcase needs 8.0 L (8.5 U.S. qts) of API Service Classification CC or CD engine oil. The transmission case requires 40.0 L (42.3 U.S. qts) of KUBOTA SUPER UDT fluid. The coolant capacity for the radiator is 7.3 L (7.7 U.S. qts) of fresh clean water with anti-freeze.
How to troubleshoot engine won't start?
If the engine won't start, common causes include no fuel (replenish fuel, see page G-29), air in the fuel system (bleed the system, see page G-29), or improper valve timing (correct or replace timing gear, see page 1-S32). Other issues could be a clogged fuel pipe or filter, excessively high viscosity oil, or a malfunctioning injection pump.
What are the hydraulic system specifications?
The hydraulic system has a pump-up capacity of 41.6 L (44.0 U.S.qts., 36.6 Imp.qts.)/min. The system pressure is 19.1 MPa (195 kgf/cm², 2773 psi). The maximum lifting force at the lower link end is 1900 kg (4200 lbs.).
