-----Cylinder Block Assembly
The cylinder block is the largest part of the excavator engine. The upper part of the block carries the cylinders and pistons, and the lower part forms the crankcase which supports the crankshaft.Cylinder blocks are made of cast iron or of aluminium alloy.
The excavator engine block contains cylindrically bored holes for the pistons. This is where the crankshaft spins, and the pistons move up and down in the cylinder bores, fired by the fuel combusting. On some engine designs, it also holds the camshaft.
