Rev. “F” 5-2-15
5-2.6.2 When output is insufficient
5-2.6.3 When engine suddenly stops
NOTE: When the engine has suddenly stopped, decompress the engine by the decomp and
turn the engine lightly by pulling on the fan belt. If the engine turns easily without
abnormalities, the cause of the trouble is usually lack of fuel or bad nozzle.
5-2.6.4 When color of exhaust is especially bad
Cause Possible Solution
Clean orifice and needle valve, being very careful not to damage
the nozzle orifice.
Check nozzle to see if good. If not, replace with new parts.
Bad valve and excessive wear of rings, pistons and liners cause
insufficient compression. Replace with new parts.
Grind valves.
Fuel is insufficient. Check fuel system.
Check lubricating oil system.
Check to see if lubricating oil filter is working properly.
Filter element deposited with impurities would cause poor
lubrication. Change element.
Check the clearance of bearing are within factory specs.
Check injection timing.
Valve clearance is wrong.
Adjust to proper valve clearance of 0.145 to 0.185mm (0.0057 to
0.0072 in.) with engine cold.
Air cleaner is dirty Clean the element every 100 hours of operation.
Fuel injection pressure is wrong. Adjust to proper pressure. 13.7 Mpa (140kgf/cm
2
, 1991psi)
Do not use poor quality fuel as it will cause wear of the
pump. Only use no. 2-D diesel fuel.
Check the fuel injection pump element and delivery valve
assembly and replace as necessary.
Carbon stuck around orifice of
nozzle piece
Compression is insufficient.
Leaking valves.
Overheating of moving parts
Injection pump wear
Cause Possible Solution
Check the fuel tank and refill the fuel, if necessary.
also check the fuel system for air or leaks.
Bad nozzle If necessary, replace with a new nozzle.
Check amount of engine oil with oil level gauge.
Check lubricating oil system.
At every other oil change, oil filter cartridge should be replaced.
Check to see if the engine bearing clearance is within factory
specs.
Moving parts are overheated due
to shortage of lubrication oil or
improper lubrication.
Lack of fuel
Cause Possible Solution
Fuel governing device bad Contact dealer for repairs.
Fuel is of extremely poor quality.
Select good quality fuel. Use No. 2-D diesel fuel only.
Nozzle is bad. If necessary, replace with new nozzle.
Combustion is incomplete.
Cause is poor atomization, improper injection timing, etc.
Because of trouble in injection system or in poor valve
adjustment, or compression leakage, poor compression,
etc. Check for the cause.
