Review PORSCHE 928s 4.7l Engine Motor Oil Pump Gear Set fits 928 1983–1984

The Porsche 928 1071157 motor oil pump gear set LM03, manufactured for the 1983 and 1984 Porsche 928 models, is an essential component of the engine's lubrication system. This gear set is specifically designed to fit the 4.7L engine and is an important replacement for worn-out or failed parts.

The LM03 oil pump gear set consists of multiple components, including the oil pump gear, the crankshaft gear, and the related bearing assemblies. These parts work together to transfer engine rotational energy to the oil pump, thereby pressurizing the engine oil and ensuring that critical engine components are adequately lubricated.

The oil pump gear is a key component of this set, as it directly engages the crankshaft gear to transmit engine power to the oil pump. It is made of high-strength materials, such as steel, to withstand the harsh operating conditions of the engine. The gear teeth are precision-machined to ensure a positive engagement with the crankshaft gear and to maintain the required oil flow rate.

The crankshaft gear, on the other hand, is designed to mesh with the oil pump gear to transmit engine power. It is manufactured to exacting standards to maintain the required gear ratio and to ensure that the oil pump receives the necessary power to perform its function effectively.

The bearing assemblies within the LM03 oil pump gear set are designed to support the loads generated by the oil pump components as they rotate. They are made of high-quality materials, such as bronze or steel, to provide the necessary strength and durability. The bearings are also designed with sufficient clearance to allow for smooth operation and to prevent excessive wear.

In summary, the Porsche 928 1071157 LM03 oil pump gear set is an essential component of the engine's lubrication system. It consists of the oil pump gear, the crankshaft gear, and the related bearing assemblies, all of which work together to transfer engine power to the oil pump and ensure that critical engine components are adequately lubricated. This gear set is specifically designed for the 1983 and 1984 Porsche 928 models with the 4.7L engine and is an important replacement for worn-out or failed parts.
