The main gas load from the cylinder cover are transmitted to the bed plate through these tie -bolts.
2 -such tie bolts are fitted to each transverse girder and they pass through the cylinder block where locking nuts are hydraulically tightened.These are also called stay bolts.
These keep the cylinder block frame and bed plates in compensation.
Tie bolts centres should be as close as possible to crankshaft Centre to reduce bending stress on the transverse girder and to prevent unbalanced loads being transferred to the welds.
