DESCRIPTION

The 3675219RX Alternator 34SI 12V N 135A Pad Mtg by Cummins is a specialized component designed for use in commercial trucks. Its purpose is to generate electrical power, charge the vehicle’s battery, and supply electricity to the truck’s various electrical systems. This part is significant in the operation of commercial trucks as it ensures that the electrical systems function correctly and efficiently, contributing to the overall performance and reliability of the vehicle 1.

Function and Operation

This Cummins part operates by converting mechanical energy from the engine into electrical energy. This is achieved through a rotor spinning inside a stator, generating an alternating current (AC) that is then converted into direct current (DC) by a rectifier. The DC power is used to charge the truck’s battery and power the electrical systems, such as lights, instruments, and other accessories. The alternator plays a role in maintaining the battery’s charge and ensuring that the electrical systems have a consistent power supply 2.

Key Features

The Alternator 34SI 12V N 135A Pad Mtg boasts several key features that enhance its performance and suitability for commercial trucks. It has a 135A output capacity, which provides ample power for the truck’s electrical systems. The 12V voltage rating is standard for most commercial vehicles, ensuring compatibility with the truck’s electrical system. Additionally, the pad mounting design allows for easy installation and integration with the truck’s engine compartment.

Benefits

Using this part offers several benefits. It contributes to improved electrical system performance by providing a stable and sufficient power supply. The enhanced reliability of the alternator ensures that the truck’s electrical systems operate consistently, reducing the likelihood of unexpected failures. Increased efficiency is another advantage, as the alternator is designed to operate effectively under the demanding conditions typical of commercial truck use 3.
