FAQ 

Q1：What signs show the engine needs to be replaced?
A1：Serious power drop during shoveling, excessive blue/black exhaust smoke, continuous abnormal knocking noise inside engine, oil and water channel serious leakage, cylinder pressure can not recover after overhaul. If overhaul cannot fix these core faults, replacing the complete engine assembly is the most practical solution.

Q2：What attention points for engine installation?
A2：Clean fuel tank, hydraulic pipeline and cooling circuit before installation. Replace new filters. Check engine mounting rubber pads, align connection interfaces, fill lubricating oil and coolant, then complete commissioning step by step. After installation, strictly follow the running-in specification, avoid full-load operation within the running-in period.

Q3：Power is still insufficient after replacing the engine, what to inspect?
A3：Check air filter clogging, fuel filter, fuel pump pressure, turbocharger status, exhaust blockage and transmission system. Insufficient power may not only be caused by engine failure. Loader hydraulic system and drive axle wear can also lead to the illusion of weak power.

Q4：What is the running-in requirement for this new engine assembly?
A4：Within the first 50 working hours, avoid long-time full-load shoveling work. Regularly check oil level, coolant and engine abnormal noise. Change engine oil and oil filter after running-in to remove tiny metal debris produced during initial operation.

Q5：How to maintain the engine to extend service life?
A5：Use qualified diesel and engine oil, replace filters according to working hours. Check air filter frequently at dusty sites. Inspect cooling system regularly to prevent overheating. Avoid frequent sudden heavy load impact as much as possible.
