How to troubleshoot a Lombardini Engine that does not start?
If your Lombardini Engine doesn't start, consider checking for the following: * Clogged pipes * Clogged fuel filter * Air inside the fuel circuit * Clogged tank breather hole * Faulty fuel pump * Jammed injector * Jammed injection pump delivery valve * Wrong injector setting * Excessive plunger blow-by * Jammed injection pump delivery control * Wrong injection pump setting
What to do if my Lombardini Engine starts but stops?
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 315 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 315 Engine?
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 15 LD 315 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 315 Engine 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 315 Engine?
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 315?
Excessive oil consumption in a Lombardini Engine can be attributed to: * Worn or jammed piston rings * Worn or scored cylinders * Worn valve guides * Worn bearings
Why are oil and fuel dripping from the exhaust of my Lombardini 15 LD 315?
If you notice oil and fuel dripping from the exhaust of your Lombardini Engine, this could be caused by worn or jammed piston rings, or worn or scored cylinders.
