Description for part number 0R-9940
Cat Reman alternator such as part # 0R9940 is 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 alternator provides like new performance and reliability at fraction-of-new costs with return of a qualifying core, while reducing the impact on the environment compared to buying new. • Cat Reman alternator is covered with a same-as-new, 12-month Caterpillar Limited Warranty1 against Caterpillar defects in material and/or workmanship. • Cat Reman offers drop-in solution.
1 Warranty can vary by model and application; limitations apply. For complete details about the applicable Caterpillar Limited Warranty, contact an authorized Cat dealer.
