The Connecting Rod (Con Rod Arm) – Part 751-10033 is a precision-engineered engine component that connects the piston to the crankshaft in internal combustion engines. It plays a critical role in converting the up-and-down motion of the piston into the rotational motion of the crankshaft — enabling the engine to produce power smoothly and efficiently.
This con rod arm is typically manufactured from durable alloy steel and designed to withstand high tensile and compressive forces inside diesel engines. It is an essential spare part for engine rebuilds, overhauls and maintenance.
Where It Is Used
The 751-10033 Connecting Rod is commonly used in:
-
Lister Petter diesel engines such as the LPW series
-
Industrial diesel engines on generators and heavy equipment
-
Fuel-powered machinery in agriculture, construction and manufacturing
-
Engine rebuilds where the con rod is worn or damaged during long service life
Key Features
-
Durable construction: Made from tough alloy steel for long service life under heavy load
-
Precision-engineered: Ensures exact fit and alignment with piston pin and crankshaft
-
Essential motion conversion: Transfers piston force to crankshaft to generate rotational power
-
High stress tolerance: Designed to withstand high compression and tensile forces inside combustion engines
-

Function in the Engine
The connecting rod links the piston to the crankshaft. During engine operation, it transfers the linear movement of the piston into rotational movement that ultimately powers the generator, vehicle or machine. This motion conversion is fundamental to internal combustion engine operation.
