Carrier 5H46-482 Piston & Pin Assembly
The Carrier 5H46-482 Piston & Pin Assembly is an essential OEM component specifically engineered for Carlyle (Carrier) 5H open-drive reciprocating compressors. This high-grade aluminum piston features a 3-1/4 inch bore diameter, designed to maintain strict compression tolerances in high-demand refrigeration and air conditioning systems. When performing a top-end overhaul on Carrier 5H46, 5H66, 5H86, or 5H126 models, utilizing this precise assembly ensures proper displacement and reduces frictional wear across the cylinder sleeve. The kit includes the piston and the corresponding wrist pin, providing the necessary structural integrity for long-stroke compressor configurations. Transitioning to these genuine parts helps prevent the oil dilution and suction pressure imbalances often caused by inferior aftermarket tolerances. Professional technicians should verify rod material (aluminum vs. steel) before installation to ensure total system balance. This assembly is built for compatibility with common refrigerants including R-134a, R-404A, and R-407C.
Key Benefits- Precise 3-1/4" Bore: Ensures an exact fit within 5H series cylinder liners to maintain optimal volumetric efficiency.
- Heavy-Duty Aluminum Construction: Provides superior heat dissipation and reduced reciprocating mass for smoother compressor operation.
- OEM Compatibility: Specifically designed for Carlyle 5H series models including the 5H46, 5H66, 5H86, and 5H126 frames.
- Full Assembly: Includes both the piston and the wrist pin to streamline the replacement process during a rebuild.
What compressor models are compatible with the 5H46-482?
This assembly is primarily used in Carlyle 5H series reciprocating compressors, specifically the 5H46, 5H66, 5H86, and 5H126 long-stroke units.
Is this piston compatible with both steel and aluminum connecting rods?
While the piston fits 3-1/4" bore applications, technicians must ensure they do not mix aluminum and steel rods within the same compressor bank as per Carlyle service bulletins.
Can I use this for R-404A refrigeration applications?
Yes, this OEM Carrier compressor part is suitable for use in systems operating with R-134a, R-404A, and R-407C refrigerants.
Item is Non Cancelable / Non Returnable
