If your Lombardini Engine starts but then stops, possible solutions include: * Clogged pipes * Clogged fuel filter * Air inside fuel circuit * Clogged tank breather hole * Faulty fuel pump * Injector jammed * Jammed injection pump delivery valve * Wrong injector setting * Excessive plunger blow-by * Jammed injection pump delivery control * Wrong injection pump setting
Why is my Lombardini 15 LD 400 Engine not accelerating properly?
If your Lombardini Engine has no acceleration, consider these potential causes: * Clogged fuel filter * Air inside fuel circuit * Clogged tank breather hole * Faulty fuel pump * Injector jammed * Jammed injection pump delivery valve * Wrong injector setting * Excessive plunger blow-by * Jammed injection pump delivery control * Wrong injection pump setting
How to fix non-uniform speed on a Lombardini 15 LD 400?
If your Lombardini Engine is running at a non-uniform speed, check for: * Clogged fuel filter * Air inside fuel circuit * Clogged tank breather hole * Faulty fuel pump * Injector jammed * Jammed injection pump delivery valve * Wrong injector setting * Excessive plunger blow-by * Jammed injection pump delivery control * Wrong injection pump setting
What causes black smoke from a Lombardini Engine?
If you see black smoke coming from your Lombardini Engine, it could be due to advanced injection or an incorrect governor linkage adjustment, or a broken or loose governor spring.
Why is my Lombardini 15 LD 400 producing white smoke?
If your Lombardini Engine is emitting white smoke, it might be due to delayed injection.
What causes too low oil pressure in a Lombardini 15 LD 400?
If the oil pressure is too low in your Lombardini Engine, check for: * Oil level too high * Jammed pressure relief valve * Worn oil pump * Air inside oil suction pipe * Faulty pressure gauge or switch * Clogged oil suction pipe
What causes excessive oil consumption in a Lombardini 15 LD 400 Engine?
