Common Questions

What models are compatible with the PD710003 sheave?
This part is specifically engineered for a wide range of Rheem and Ruud package units, most notably the RJNL-B series heat pumps and related gas/electric platforms. Always verify your specific model and serial number for exact fitment.

Can I use a universal pulley instead of this OEM sheave?
While universal pulleys exist, the PD710003 provides the exact pitch and balance required by the manufacturer. Using non-spec sheaves can lead to incorrect blower speeds, increased noise, and vibration issues.

Does this part include the set screw?
Most Rheem-Ruud fixed sheaves come with the necessary set screws to secure the 1-inch bore to the shaft, though we recommend inspecting your existing keyway for wear during installation.
