When the engine runs for 1200~1500 hours, take apart the oil sump, disassemble the
main bearing shells, thrust plate, connecting rod bearing shells, crankshaft bearing shells
and check their wear conditions. Replace the one that wears out and clean the oil sump
at the same time. Then assemble them altogether.

If anyone or more is replaced, such as crankshaft, piston, piston ring, cylinder sleeve,
connecting rod, connecting rod bearing shell, main bearing shell, crankshaft thrust plate,
camshaft, camshaft bushing, tappet, cylinder block etc., diesel engine can run properly
only after the break-in period. Engine cannot run with heavy load and at high speed just
after replacement lest the components be destroyed and engine lifespan be reduced.
