1. Struktur crankshtle
The crankshaft is generally composed of a front end, a main shaft neck, a crank, a counterweight, a connecting rod journal and a rear end. A crank is composed of a connecting rod journal and its left and right principal journals. The number of crank of a crankshaft depends on the number and arrangement of cylinders. The crankshaft of a single cylinder engine has only one crank; The number of crank of the crankshaft of an in-line engine is equal to the number of cylinders; The number of cranks in the crankshaft of a V engine is equal to half the number of cylinders. Aci pungkur payuneun cengkéhna dilengkepan pulna, gear, sareng sajabana, anu dianggo pikeun nyetir pompa cai sareng mékanisme klak. The spindle neck of the crankshaft is installed in the main bearing seat of the cylinder body and is used to support the crankshaft. The connecting rod journal is used to install the connecting rod, and the crank connects the main shaft journal with the connecting rod journal. In order to balance the centrifugal force when the crankshaft rotates, a balance block is provided on the crankshaft. A connecting flange is provided at the rear end of the crankshaft to connect the flywheel to the crankshaft by bolts. To lubricate the connecting rod journal, a lubricating passage is drilled from the main shaft journal to the connecting rod journal.

In order to prevent the rotation of the thrust pad, the thrust pad has a bulge stuck in the groove. Some thrust pads use 4 pieces to form two positive circular limits, and some use 2 pieces of limits. The side with anti-friction metal should face towards the crankshaft.
