3418517 4910522 3000791 3811994 3043911 3811995 Diesel Engine Connecting Rod For K19 KTA19 QSK19

Connecting rod (also called a con-rod) is a critical link between the piston and the crankshaft. Its primary function is to transmit the massive combustion force from the piston to the crankshaft, converting the reciprocating linear motion of the piston into the rotational motion of the crankshaft to deliver engine power. This connecting rod 3418517 4910522 3000791 3811994 3043911 3811995 is engineered for maximum durability and precise fitment in K19 KTA19 QSK19 engines. Manufactured to meet or exceed OEM standards, it ensures optimal engine performance and a long service life under heavy-duty conditions.

Whether for full engine rebuilds or quick replacements, DDP Engine provides you with the most reliable parts at unbeatable wholesale prices.

Application:
K19: Refers to an early 19L inline six-cylinder engine with a mechanical fuel system (PT pump), commonly found in heavy-duty trucks, construction machinery (such as mining trucks and bulldozers), stationary/mobile generator sets, and marine propulsion systems from the 1980s to the 2000s. It was primarily designed for non-electronic, high-torque operation.

KTA19: A turbocharged and aftercooled version of the K19, still mechanically controlled, with a power output ranging from approximately 450 to 650 horsepower. It was mainly used in mining machinery, port cranes, large construction vehicles, and medium-sized vessels, emphasizing durability and low-speed torque. Some export and off-road equipment still use it. QSK19: An electronically controlled high-pressure common rail (QSK = Quantum Series K) 19L engine, meeting Euro III/IV emission standards and above, with a power range of approximately 500–900 hp (369–669 kW). It is widely used in modern heavy-duty tractors, off-road mobile machinery (such as large excavators and drilling rigs), emergency power stations, and railway locomotive auxiliary power, meeting mainstream emission and intelligent control requirements since 2000.
