In our workshop, a Caterpillar 3306 DI engine, originating from a crusher, has been rebuilt.
Due to the borderline wear of the engine block, crankshaft and several connecting rods, we started the repair by preparing the appropriate spare parts. After assembling the main components, we started the repair, which included, among other things, replacing the main bearings, connecting rod bearings and bushings, as well as cylinder liners and pistons with rings. Camshaft bearings, due to wear marks, were replaced - at the same time providing appropriate working conditions for the new camshaft. The timing system, in addition to the new camshaft, received new pushrod cups and a set of timing gear bearings. In the fuel system, new injectors were installed, and the injection pump was regenerated. The engine cooling system received a new water pump and thermostat. The worn oil pump was also replaced with a new one. The cylinder head required repair, which after a leak test and full machining was equipped with a full set of new guides, springs and valves.
In addition, the following were regenerated: crankshaft, connecting rods, turbocharger, alternator and starter.
Finally, the engine was assembled on a new set of seals, gaskets and filters.
After the repair, the engine was checked and initially run-in on the engine dynamometer in our workshop.
At the customer's request, we also implemented a fully automatic system that will prevent engine damage due to low oil pressure or overheating.
