SECTION 8. TROUBLESHOOTING
ENGINE STARTS DIFFICULT
Possible Cause
Remedy
Increased fuel thickness or
viscosity.
-
Check fuel tank and fuel filter.
-
Remove water, dust and other dirt.
-
As the filter is used to clean the entire fuel, replace the filter if there is
water or foreign matter on it.
Air or water penetration into
the fuel system
-
The fuel pump will not function properly if there is air in the fuel filter or
injector pipes.
-
Check if the fuel tank cap is loose to ensure proper fuel pumping
pressure.
-
To remove all the air from the fuel system, follow the procedures
described in the manual.
Soot accumulation on the
injection nozzle hole
-
This occurs when the fuel is contaminated with water or dirt. Clean the
injection nozzle without damaging the hole.
-
Check if the injection nozzle functions properly; if not, replace the
injection nozzle.
Valve clearance out of range
-
Adjust the valve clearance
Valve leakage
-
Tighten the valve.
Incorrect fuel injection timing
-
Adjust the injection timing.
Engine oil thickens in cold
weather, slowing down the
engine operation.
-
Replace the oil with an oil type suitable for the weather conditions.
Low compression pressure
-
It is caused by bad valve adjustment or when the piston, piston ring or
liners are over worn.
-
Replace wearing parts with new parts.
Empty battery
-
Recharge the battery
-
Use a pressure reducing device.
-
Remove and recharge the battery when the tractor Is not in use,
especially during winter, and reconnect it when you will use the tractor.
Moving parts overheat
-
Check the engine lubrication system.
-
Check the engine filter for congestion; replace it if congested.
-
Check the crank shaft end play.
-
Check injection timing.
Injection pump wear
-
Avoid using low quality fuel; this may cause pump wear. Use diesel fuel
number 2 only.
-
Check fuel injection pump elements and intake valve and replace these
parts if necessary.
