The number of main bearings is primarily determined by the overall load factor and maximum engine speed. [1] Increasing the number of bearings in an engine will generally increase the size and cost of the engine, but also reduces bending stress and deflection caused by the distance from the crank pins to the nearest bearings. Most engines have ...
The 1ND-TV (1.4 D-4D) is a compact inline-four cylinder turbocharged diesel engine used in various markets including Japanese, Indian and European markets. It was introduced into European market in 2002 with the Yaris XP10 and XP20 Yaris Verso. [1] [2] it was Toyota's first
A crankpin or crank pin, also known as a rod bearing journal, [1] is a mechanical device in an engine which connects the crankshaft to the connecting rod for each cylinder. It has a cylindrical surface, to allow the crankpin to rotate relative to the "big end" of the connecting rod.

For instance, .001 of an inch worn off of the engine's main bearings can cause up to a 20% loss in oil pressure. [6] Simply replacing worn bearings may fix this problem, but in older engines with a lot of wear not much can be done besides completely overhauling the engine. Particles in the oil can also cause serious problems with oil pressure.
A cross-bolted bearing is a bearing, usually a crankshaft main bearing of a piston engine, reinforced with additional transverse bolts.Most bearing caps are retained by two bolts, one on each side of the bearing journal, and parallel to the cylinder axis (or, on vee engines, parallel to an axis bisecting the vee angle).
A sealed deep groove ball bearing. In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, [1] is a bearing which carries a load by placing rolling elements (such as balls, cylinders, or cones) between two concentric, grooved rings called races.
