Trane SHE1116 Sheave

The Trane SHE1116 Sheave is a precision-engineered OEM replacement component designed to maintain critical drive ratios in high-performance Trane HVAC systems. This industrial-grade sheave, which also serves as a cross-reference for SHE5413, features a 5.75-inch diameter and a 1-inch bore, ensuring exact alignment and torque transfer within the blower assembly. Built for durability in commercial and industrial air handling units, this cast iron sheave minimizes vibration and reduces mechanical drive losses by securing a tight fit on the 1" motor or fan shaft. Since Trane systems rely on specific RPM calculations for optimal static pressure and airflow, using this HVAC blower pulley ensures the drive belt tracks correctly and maintains the intended system efficiency. For technicians troubleshooting belt slippage or inconsistent fan speeds, this sheave provides a high-tolerance solution that integrates seamlessly with existing drive mechanisms without necessitating modifications to the Trane HVAC pulley system configuration.

• Exact Calibration: The 5.75" diameter maintains the factory-specified blower RPM, ensuring the system hits its air delivery targets across the heat exchanger.
• Perfect Shaft Seating: A precision-machined 1-inch bore allows for a slide-fit installation with secured set-screw positioning to prevent keyway damage and shaft scoring.
• Reduced Mechanical Wear: Using an OEM Trane SHE1116 replacement reduces premature belt fatigue and bearing stress by eliminating the wobble-effect often found in generic alternatives.
• High Compatibility: Direct replacement for SHE5413, simplifying inventory management for contractors servicing older WSC, THC, and YSC Series units.

What is the difference between SHE1116 and SHE5413?
Technically, they are the same specification. The SHE1116 is the current manufacturer part number used to replace the legacy SHE5413 designation, maintaining the identical 5.75" OD and 1" bore dimensions.

Can I use this sheave if my shaft has a different bore size?
No. This sheave is specifically bored to 1 inch. Forcing a fit or using bushings on an undersized shaft is not recommended as it compromises the balance of the blower assembly and can lead to motor failure.

Does this sheave include the set screw?
Yes, standard OEM sheave replacements include the necessary set screw for locking onto the shaft keyway to ensure static positioning during operation.
