20R-3603: Cat® Reman 24 Volt Alternator

Description: Cat Reman alternators such as 20R-3603 are designed to energize the battery to power your machine. There are two types: Brush-Type Design uses one-piece brushes for less maintenance, with constant-pressure springs for even brush wear; and our Brushless Design has fewer moving parts, tighter air gap tolerances and quality sealing for longer life in harsh environments (dirt, dust, heat or cold) compared with Brush-Type. Electronic voltage regulators and a high-efficiency cooling system are built in. We replace all gaskets and seals, starter O-rings, seals, and boots with new. Cat Reman alternators are quiet, compact, and lightweight, designed to be part of a balanced electrical system. Each unit includes all critical engineering updates, and is rigorously tested against original specifications, so you know you’re getting genuine Caterpillar reliability. Attributes: • You're buying less downtime and lower repair bills, helping you reduce owning and operating costs. • Cat Reman alternators provide like new performance and reliability at fraction-of-new costs while reducing the impact on the environment compared to buying new. • All Cat Reman products come with a same-as-new Caterpillar Limited Warranty. 1 • Cat Reman offers off-the-shelf availability. 2 1 Warranty can vary by model and application; limitations may apply.
