The engine overhaul was started from the replacement of main bearings, conrod's bearings and bushings, pistons with rings. New injectors and a regenerated high pressure pump were installed in the fuel system. The engine cooling system received a renew water pump and a new thermostat. A new oil pump is now responsible for correct oil pressure, while a new oil cooler takes care of its correct temperature. The engine block was reconditioned including the camshaft bearing shells replacement - on this occasion the camshaft and tappets were replaced with new ones.
Due to the specific structure of the cylinder head, it was necessary to perform a major overhaul in terms of replacing the injector sleeves, planning, leak test, replacing valves with guides, springs, tappets and valve seats.
In addition, the following elements were regenerated: crankshaft, connecting rods, turbocharger and starter.
Finally, the engine was assembled with a new set of seals, gaskets and filters.
After engine assembly the unit was tested on our test bench for runing and proper work.
