oliver 1850 hydraulic pump made in china

Nusbaum Farms LLC Bellfountain, ORGot the hyd pump out of the 1850 today and it is in need of replacement as we suspected. There are three possible different pumps for that tractor, A&I sells one but it is impossible to tell which one using an old Oliver parts book. So I called the dealer and got the number crossed over to a White number. Here"s the pricing from different locations:

The historical region now known as China experienced a history involving mechanics, hydraulics and mathematics applied to horology, metallurgy, astronomy, agriculture, engineering, music theory, craftsmanship, naval architecture and warfare. Use of the plow during the Neolithic period Longshan culture (c. 3000–c. 2000 BC) allowed for high agricultural production yields and rise of Chinese civilization during the Shang Dynasty (c. 1600–c. 1050 BC).multiple-tube seed drill and the heavy moldboard iron plow enabled China to sustain a much larger population through improvements in agricultural output.

For the purposes of this list, inventions are regarded as technological firsts developed in China, and as such does not include foreign technologies which the Chinese acquired through contact, such as the windmill from the Middle East or the telescope from early modern Europe. It also does not include technologies developed elsewhere and later invented separately by the Chinese, such as the odometer, water wheel, and chain pump. Scientific, mathematical or natural discoveries made by the Chinese, changes in minor concepts of design or style and artistic innovations do not appear on the list.

Philon of Byzantium (3rd or 2nd century BC)chain drive and windlass used in the operation of a polybolos (a repeating ballista),chain pumps which had been known in China since at least the Han Dynasty (202 BC – 220 AD) when they were mentioned by the Han dynasty philosopher Wang Chong (27 – c. 100 AD),clock tower built at Kaifeng in 1090 by the Song Chinese politician, mathematician and astronomer Su Song (1020–1101).

Escapement, hydraulic-powered (use in clock tower): The escapement mechanism was first described for a mechanical washstand by the Greek Philon of Byzantium who also indicated that it was already used for clocks.Yi Xing (683–727) of the Tang Dynasty (618–907) for his water-powered celestial globe in the tradition of the Han dynasty polymath and inventor Zhang Heng (78–139), and could be found in later Chinese clockworks such as the clock towers developed by the military engineer Zhang Sixun (fl. late 10th century) and polymath inventor Su Song (1020–1101).striking clock.pendulum resting and releasing its hooks on a small rotating gear wheel, the early Chinese escapement employed the use of gravity and hydraulics.waterwheel (which acted like a gear wheel) would be filled one by one with siphoned water from a clepsydra tank.

air conditioning, the Han Dynasty craftsman and mechanical engineer Ding Huan (fl. 180 AD) invented a manually operated rotary fan with seven wheels that measured 3 m (10 ft) in diameter; in the 8th century, during the Tang Dynasty (618–907), the Chinese applied hydraulic power to rotate the fan wheels for air conditioning, while the rotary fan became even more common during the Song Dynasty (960–1279).Georg Agricola (1494–1555).

archaeological site in Anatolia (Kaman-Kalehoyuk) and is about 4,000 years old.East Africa, dating back to 1400 BC.Falcata were produced in the Iberian Peninsula, while Noric steel was used by the Roman military.cast iron from the late Spring and Autumn period (722–481 BC), produced steel by the 2nd century BC through a process of decarburization, i.e. using bellows to pump large amounts of oxygen on to molten cast iron.Liu An (179–122 BC). For steel, they used both quenching (i.e. rapid cooling) and tempering (i.e. slow cooling) methods of heat treatment. Much later, the American inventor William Kelly (1811–1888) brought four Chinese metallurgists to Eddyville, Kentucky in 1845, whose expertise in steelmaking influenced his ideas about air injection to reduce carbon content of iron; his invention anticipated the Bessemer process of English inventor Henry Bessemer (1813–1898).

pestle and mortar to pound and decorticate grain, which was superseded by the treadle-operated tilt hammer (employing a simple lever and fulcrum) perhaps during the Zhou Dynasty (1122–256 BC) but first described in a Han Dynasty (202 BC – 220 AD) dictionary of 40 BC and soon after by the Han dynasty philosopher and writer Yang Xiong (53 BC – 18 AD) in his hydraulic power, which the Han dynasty philosopher and writer Huan Tan (43 BC – 28 AD) mentioned in his Xinlun of 20 AD, although he also described trip hammers powered by the labor of horses, oxen, donkeys, and mules.waterwheels were made in subsequent Chinese dynasties and in Medieval Europe by the 12th century.Pliny, Roman Empire by the 1st century AD.
