Bard part number 5070-005BX is an OEM drive belt used on belt driven Bard HVAC blower assemblies and is commonly referenced as the replacement belt for the 5070-033 blower motor application. A worn or stretched belt can cause reduced airflow, squealing, and uneven cooling or heating, so swapping in the correct Bard belt helps restore proper blower speed and steady air delivery through the unit. For best results, confirm the belt size and the unit model and serial compatibility in your Bard parts manual, then set proper belt tension and inspect pulleys and bearings while you have the blower section open.
* Orders less than $50 may incure a minimum order fee.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
