A tie rod is a long strong rod with bolts or tie bolts at both ends. This rod holds the three major engine components i.e. Cylinder block or entablature, “A” frame, and crankcase in compression and transmits the firing load to the bedplate. It is typically made of a strong and durable material such as steel, and it has threads on both ends to allow for adjustable lengths.


The tie rods are fitted through the above-mentioned components and are hydraulically tightened so that the whole engine can be held in compression. In addition, the tie rod also helps to distribute loads evenly across the engine, which can help to prevent damage and prolong its lifespan.
