2.8L series high-end diesel engines are manufactured by JAC. With the disadvantages of compact structure, high

power, little vibration, low noise and low price, it is an ideal power for 0.5-4 ton series light truck and all kinds of variants
or mechanisms.

Being used, diesel engine will run abnormally due to reasons of parts wearing, tightening parts loosening, clearance

change, oil going bad. If it is found starting difficultly, power falling, oil consumption adding, please do regular mainte

nance of cleaning, checking, lubricating, adjusting or replacing parts according to the technical state and working time
or vehicle traveled distance.

Please read this manual before using 2.8L series diesel engine and operate it strictly with the manual so as to make
