Cylinder Head Welding For 4 Stroke Engines

of
MaK REParts

Cylinder heads for 4 stroke engines have a complex design. The inlet air, exhaust gas, fuel injection passages and cooling water passages are incorporated. These are normally manufactured from spheroidal graphite or nodular cast iron. Although not as strong as cast steel, it is easier to cast and maintain reasonable strength under load. Cast iron is the most difficult to repair when it fractures all the common metals.

Poor cooling can cause damage to cylinder heads, leading to thermal fatigue. Deposits form in the cooling chambers, and cracks may form between the valve pockets and/or the cooling water chambers. Caterpillar Motoren does not recommend welding as a repair option for cylinder heads due to the high mechanical stress in the areas and the risk of subsequent failure.

The REParts™ program allows you to exchange your old cylinder heads for new or used ones at a competitive price.
