6. Installation Notes & Torque Practice
7. Manufacturing & Supply Assurance
Forged on a dedicated line with quench-and-temper heat treatment, then CNC-machined to ±0.005 mm and dynamically balanced. Monthly production capacity: 5,000+ crankshafts; 1,000+ units of 17-44075-00 held in stock for global dispatch.
Compared with non-OEM replacement shafts, the 17-44075-00 extends compressor service life by 30%+ and reduces power transmission loss by up to 15% through precise geometry.
8. Buyer FAQ
Q1. Which compressors does 17-44075-00 fit?
Carrier 05G series compressors used in refrigerated trucks, bus air conditioning systems and commercial cold-chain equipment, matching the 41 CFM airflow platform.
