The Permco 7400-9931-0005 or 740099310005 is a vane pump for PTO hydraulic pump applications, carrying the Permco model code PT7DSW-B35-XL00-A1-W1. In a vane pump, sliding vanes ride in a spinning rotor and sweep the housing wall, so the chambers between them grow to draw fluid in and shrink to push it out under pressure. Abrasive contamination wears the vanes, and a pump that is wearing tends to whine or knock, cycle slowly under load and let output pressure sag. A genuine Permco part from Pro Gear and Transmission.
