It features a 10-bolt mounting pattern with extended-length fasteners and a shift cover that rotates a full 360 degrees for flexible installation. The rotatable pump flange and increased housing clearance simplify installation in tight bays. Tapered roller bearings extend service life, and an increased output shaft diameter adds durability under load.
