Diesel starts and stalls immediately: Fuel filter plugged. Filter maintenance required. Fuel injection pump malfunctioning. Install a new pump or rebuild. Clogged air filter. Change air filter element.

Engine overheated: Dirty radiator core or faulty radiator cap. Change cap or clean radiator. Low coolant level. Add coolant and check the components of cooling system. Fan belt is loose or defective. Change the fan belt. Engine oil level is insufficient. Fill up the oil to required level.

Low engine power: Dirty or faulty injection nozzles. Check and replace nozzles if required. Fuel hoses or lines are dirty. Clean fuel system lines and hoses. Restricted intake air. Install new air filter element. Leaking cylinder head gasket. Gasket should be replaced.

Engine knocks or noises: Engine is not fully warmed up. Normalize the temperature by warming up the engine. Low engine oil level. Add oil to the engine crankcase. Fuel injection pump timing is wrong. Adjust according to specifications. Broken or worn pistons. Replace the pistons. Connecting rod is misaligned or worn. Need to align or replace the connecting rod.

Engine stalls while idling: Incorrect low idle speed adjustment. Correct the settings. The valve clearance is not adjusted. Adjust valve clearance. Defective fuel injection pump. Repair or replace injection pump.

Insufficient oil pressure: Low crankcase oil level. Add oil to the engine crankcase. Oil pump failure. Inspect and change as required. Oil filter clogging. Service or replace engine oil filter.

Transmission makes excessive noise: Damaged gears or incorrect backlash. Change worn gears or adjust backlash correctly. Shift forks are bent or worn out. Change the shift forks. Shaft splines are worn or stuck. Change the shaft. Transmission oil level is low. Add oil to the transmission housing. Worn or broken bearings. Install new bearings. Transmission fluid contamination. Transmission fluid change required.

Difficult to shift gears: Gear shift linkage is worn or rusty. Shift linkage need to be replaced. Clutch is faulty or misadjusted. Adjust or change the clutch. Shift forks are bent or worn out. Install new shift forks. Gearshift mechanism malfunction. Identify and replace failed parts.

Transmission oil pressure is low: Transmission oil level is low. Need to add transmission oil. Clogged transmission fluid filter (if equipped). Clean or change transmission fluid filter. Defective relief valve. Install a new valve.

Transmission oil leaks: Seals or gaskets are worn. Install new components. Transmission oil level is exceeded. Correct the oil volume.

Massey Ferguson 263 Hydraulics Troubleshooting

Hydraulic system is overheated: Hydraulic oil type is wrong. Correct type of oil must be used. Hydraulic fluid contamination. Change hydraulic fluid. Air in hydraulic pipes. Bleed hydraulic pipes. Faulty main relief valve. Relief valve replacement required.

Insufficient hydraulic oil pressure: Insufficient hydraulic oil. Check and refill the hydraulic oil. Hydraulic oil filter is clogged. Service or replace the hydraulic filter. Leaking hydraulic pipes. Identify leaks in the system and repair it. Hydraulic spool valve is not set properly. Set the spool valve properly. Damaged hydraulic pump. Install a new hydraulic fluid pump. Broken hydraulic cylinder. Replace or repair hydraulic cylinder.

3-point hitch fails to lift or lifts slowly: Hydraulic pump malfunction. Repair or replace hydraulic fluid pump. Main relief valve malfunctioning. Relief valve must be changed. Defective hydraulic spool valve block. Repair or replace hydraulic valve. Defective hydraulic cylinder. Replace or repair hydraulic cylinder. Hydraulic fluid is insufficient. Fill the system to proper hydraulic fluid level. Clogged hydraulic fluid filter element. Hydraulic filter maintenance required. Excessive loading on the hitch. Reduce hitch load.

3-point hitch can't drop or drops too slowly: Hydraulic cylinder failure. Change or repair hydraulic cylinder. Hydraulic control valve block is out of adjustment. Control valve needs to be adjusted. Hitch rock shaft is worn. Replace the shaft. The hitch has not been adjusted. Adjust three-point hitch as required.

Hitch drop or lift is jerky: Contaminated hydraulic fluid. Change hydraulic fluid. Defective hydraulic pump. Change or repair hydraulic fluid pump. Air in hydraulic system. Bleed air from hydraulic system. Damaged hydraulic control valve. Repair or replace the valve. Faulty hydraulic cylinder. Repair or replace hydraulic cylinder.
