Perkins Alternator Pulley - OEM Number: T432243

The Perkins Alternator Pulley (OEM T432243) is a direct replacement drive component designed for use on Perkins diesel engine alternator assemblies. It is mounted to the alternator shaft and works in conjunction with the engine drive belt to transmit rotational force, enabling the alternator to generate electrical power for the machine’s charging system.

Manufactured to OEM specifications, this pulley is engineered for strength, balance, and reliable belt engagement under continuous engine operation. It ensures correct belt alignment and smooth power transfer, helping to maintain efficient alternator performance and reduce belt wear.

FUNCTION AND OPERATION

• Transfers engine drive belt motion to the alternator
• Enables alternator rotation and electrical power generation
• Maintains correct belt tracking and alignment
• Reduces belt slip and wear under load
• Supports stable charging system performance
