Ingersoll Rand 3/4” Impact And Dayton 1/2” Impact (for Parts Or Repair)

Unknown model on the ingersoll rand. The Dayton model number looks like “5Z336”

Both will spin on the air compressor, I think they’re just gummed up. They’re both low on power. That being said there may be more issues with these than I think. These are for parts or repair. They do spin in both directions. But both have issues.
