Applicable Models & Applications
These pistons suit Hitachi engines, sized to the bore grade so compression, ring position and oil control match the block. Suitable for the corresponding machine model and configuration — please verify the machine model, serial number and part number match before ordering.
Maintenance & Replacement
Pair pistons with fresh rings and liners during overhaul, and set ring end gaps and side clearance to spec; inspect for slap, scuffing or a cocked ring when performance drops. Early signs it may need attention: A cold piston slap that lessens as the engine warms; Increased blow-by and blue smoke when ring lands or grooves wear; A penetrating, heavy knock that worsens under load with a scored skirt.
Installation Essentials
Work on a clean machine with the engine off and the relevant system drained or depressurised as required, and confirm the part number against your machine model and serial number before ordering. Clean the ring grooves to remove carbon and measure end gaps before assembly. After installation, run the machine and check for leaks, unusual noise or abnormal travel before returning it to service, and retighten where the manual calls for it after the first hours of operation.
