Abstract
A cylinder block for an internal combustion engine which, in use, supports a rotary crankshaft 40, the block having pairs of opposed lock width surfaces 37 formed thereon for forming an interference fit with respective co-operating lock width surfaces 38 on the crankshaft bearing caps 34 which in use are secured to respective bearing cap support surfaces 36 also formed on the block 31. The lock width surfaces 37, 38 are spaced from the respective bearing cap support surfaces 36 so as to improve stress cracking resistance of the block 31.
