Valve lifter for Kobelco 7055

The valve lifter, part number 2420T5454D1, serves as a component within the engine valve train of the Kobelco 7055 crane. Its primary function involves transmitting the mechanical movement from the camshaft lobes to the intake and exhaust valves. By maintaining this synchronized motion, the lifter ensures that the valves open and close at the precise intervals required for the intake of the air-fuel mixture and the expulsion of exhaust gases during the combustion cycle.

This component is engineered for fitment in the Kobelco 7055 crane engine. Proper operation of the valve lifter is necessary to maintain the timing and mechanical efficiency of the valve train assembly. Regular inspection of these components helps in identifying wear or surface irregularities that could otherwise affect the synchronization of the engine's valve timing.

In internal combustion engines, valve lifters act as the interface between the camshaft and the rest of the valve train, such as pushrods or rocker arms. Their movement translates the rotational energy of the camshaft into the linear motion needed to cycle the valves. Consistent performance of these parts is required to manage the valve lift and duration, which directly influences engine power output and fuel efficiency.
