Cylinder heads are always under heavy stress. It is commonly observed that after certain hours of operation, cylinder head valves, valve guide and valve seats loose their original profile and get worn out because of continuous running of the diesel engine. It is important that the cylinder heads are subject to periodic inspection.
RA Power Solutions undertakes complete inspection of all the moving and stationery parts of cylinder heads. In case the wear and tear of valve seats and valves is not excessive, it is recommended to go for the lapping. We have in-house valve lapping equipment and with the help of experienced technicians the valve seats and valve profile is maintained to the original. In case the wear and tear or damage to the valve seat is on higher side the replacement of cylinder head valve seat and valve is recommended.
All the cylinder heads received at our works are subject to chemical cleaning, short blasting and crack detection by MPI procedure. In case of pressure drop or crack in cylinder head we suggest and undertake repairs by cold method i.e. metal stitching and metal locking, This is the proven method of repair of crack in cylinder heads as it is a cold process of repair and no heat is generated.
