Massey Ferguson 65 Diesel Engine Troubleshooting

Diesel hard to start or doesn't start: Clogged fuel filter. Change filter element. Air trapped in fuel system. Bleed air. Fuel injection nozzles are faulty or clogged. Change fuel injection nozzles. Faulty fuel injection pump. Install a new pump or rebuild.

Engine stops unexpectedly during operation: Fuel injection pump timing is wrong. Set the fuel pump timing correctly. Fuel filter plugging. Clean the filter or install new filter element. Engine is cold. Warm up engine as required.

Diesel starts and stops: Clogged fuel filter. Change the filter element. Fuel injection pump malfunctioning. Replace injection pump or repair it. Clogged air cleaner. Service air cleaner.

Engine is overheated: Dirty radiator core or faulty radiator cap. Clean radiator or change cap. Low coolant level. Fill the cooling system and check components for leaks or other faults. Fan belt slipping or worn. Replace the fan belt. Engine oil level is insufficient. Fill up the oil to required level.

Reduced engine power: Clogged injection nozzle. Check and replace nozzles if required. Fuel lines or hoses are dirty. Clean fuel system hoses and lines. Clogged air filter. Change air filter element. Cylinder-head gasket is broken. Gasket should be replaced.

Abnormal engine noise or knocking: Coolant temperature is low. Warm up the engine. Lack of engine oil. Check and refill engine oil. Fuel injection pump timing is not adjusted. Adjust as recommended. Pistons are broken or worn. Pistons need to be replaced. Connecting rod is worn or not aligned. Need to change or align the connecting rod.

Engine stalls at low idle speed: Low idle speed set incorrectly. Adjust low idling as recommended. Valve clearance is not correct. Have it adjusted. Fuel injection pump is not working correctly. Change or repair the pump.

Oil pressure too low: Not enough oil in the engine. Need to add oil. Defective oil pump. Replace as required. Clogged oil filter. Replace or service engine oil filter.

Transmission makes excessive noise: Defective gears or improper backlash. Adjust backlash correctly or replace the gears. Shift forks are bent or worn out. Replace the shift forks. Worn or stuck shaft splines. Replace the shaft. Transmission fluid insufficient. Checking transmission fluid level and add if necessary. Worn or damaged bearings. Change the bearings. Transmission fluid contamination. Change the fluid.

Gears are hard to shift: Rusty or worn gear shift linkage. Install a new gear shift linkage. Malfunction or incorrect clutch adjustment. Clutch adjustment or replacement required. Damaged or worn gear shift forks. Replace the shift forks. Gearshift mechanism malfunction. Identify and replace failed parts.

Transmission oil pressure is low: Lack of transmission oil supply. Check and refill the transmission oil. Transmission fluid filter is clogged (if fitted). Replace or service transmission fluid filter. Defective relief valve. Replace valve as required.

Transmission fluid leaking: Worn seals or gaskets. Change defective gaskets or seal. Transmission oil level is high. Correct the oil volume.

Massey Ferguson 65 Hydraulics Troubleshooting

Excessive hydraulic system heat: Improper hydraulic fluid type. Use the proper type of hydraulic fluid. Hydraulic fluid contamination. Change hydraulic fluid. Air in hydraulic pipes. Bleed hydraulic pipes. Main relief valve is faulty. Install a new relief valve.

Low hydraulic oil pressure: Hydraulic fluid level low. Fill up the hydraulic fluid. Dirty hydraulic oil filter element. Install a new hydraulic filter element. Hydraulic piping is leaking. Inspect hydraulic system for leaks and repair it. Incorrect adjusted hydraulic spool valve. Adjust the spool valve correctly. Faulty hydraulic pump. Repair or replace hydraulic fluid pump. Hydraulic cylinder malfunction. Repair or change hydraulic cylinder.

3-point hitch won't lift or lifts slowly: Hydraulic pump is faulty. Change or repair hydraulic fluid pump. Damaged main relief valve. Install a new relief valve. Faulty hydraulic spool valve. Change or repair hydraulic valve. Hydraulic cylinder not working. Replace or repair hydraulic cylinder. Hydraulic oil level low. Need to add oil. Dirty hydraulic oil filter element. Install a new hydraulic filter element. Excessive loading on the hitch. Reduce loading.

Hitch cannot be dropped or dropping is too slow: Hydraulic cylinder malfunction. Repair or install a new hydraulic cylinder. Hydraulic control valve block is out of adjustment. Control valve needs to be adjusted. Hitch rock shaft is damaged. Install a new shaft. Hitch is out of adjustment. The hitch must be adjusted.

Jerky lifting or lowering of three-point hitch: Hydraulic oil is contaminated. Fill up with fresh hydraulic oil. Defective hydraulic pump. Change or repair hydraulic fluid pump. There is air in the hydraulic system. Bleed hydraulic system. Faulty hydraulic spool valve. Repair or replace hydraulic valve. Damaged hydraulic cylinder. Repair or change hydraulic cylinder.
