Cylinder Heads

Large bore engine cylinder heads are blasted clean and pressure tested. Magnaflux test is performed. When necessary, combustion chamber is cropped off, mating faces are machined and a new chamber is installed.

On heads with different configurations, cracks are gouged out. Preheating of head is carried out and welding of gouged area is done with submerged arc welding at constant temperature. Heads are then stress relieved and all landing faces are machined. On small engines we also bore out pockets to insert exhaust and inlet valve seats.

All our work is approved by classification societies and performed to manufacturers' specifications.
