The Chelsea PGP051 hydraulic pump, part number 3139610663, is a genuine Chelsea unit configured for PTO-driven hydraulic systems on heavy-duty trucks. The part designation decodes to a 2/4B port arrangement with 7/8 NPT porting and a 13-tooth drive gear. The 13-tooth gear spec is a key selection point when matching this pump to a PTO output shaft. Pro Gear and Transmission carries this as a genuine Chelsea part. If you need help confirming the right pump configuration for your PTO and hydraulic circuit, give us a call before ordering.
