Premium Remanufactured Bock FK40-655K Bus AC Compressor – Factory Restored Heavy-Duty Commercial HVAC Core | 12V/24V R134a Available

Product Overview

Hunan Weili Auto Parts Appliance Co., Ltd. is an IATF 16949-certified National High-Tech Enterprise and an officially recognized provincial "Specialized, Sophisticated, Special, and Novel" (S3N) "Little Giant" in China's automotive industry. With over 17 years of expertise specifically in commercial vehicle climate control systems, we bring world-class remanufacturing technology to your fleet management and distribution network.

Our Remanufactured Bock FK40-655K compressor reflects a perfect synergy of classic durability and modern re-engineering. Unlike cheap grade-B replacements, our "Core Revival" process involves a complete tear-down, high-pressure ultrasonic cleaning, and precision CNC re-machining of the housing and crankcases. Every critical wear part—including pistons, connecting rods, bearings, and sealing rings—is replaced with brand-new, high-grade components.

This rigorous restoration ensures that the refurbished unit delivers original design efficiency, reduced frictional noise, and long-term operational stability, catering specifically to the rigorous demands of global commercial transport. Supported by our in-house R&D team, which maintains close ties with Tsinghua University and Hunan University, this remanufactured Bock compressor is the ultimate economical solution for bus operators and aftermarket parts suppliers seeking trusted reliability without the premium cost of buying brand new.
