HINO 700 PROFIA SH1E FS1E FR1E SS1E FM2P KOBELCO SK460-8 SK480-8 P11C P11C-T P11C-U 10.5L 4-HOLE HUB DUAL OVAL FLANGE PORTS PULLEY TYPE ENGINE COOLING WATER PUMP ASSY WITH BACK PLATE (OE: 16100-E0490 / 16100E0490 / S1610-0E0490 / 16100-3811 / 16100-4120 / 16100-3311 / 16100-3611 / HWP-053)

Overview

The Hino 700 / Profia / Kobelco P11C Pulley-Hub Type Engine Water Pump Assembly (Water Pump Assy 16100-E0490 / 16100E0490 / S1610-0E0490 / 16100-3811 / 16100-4120 / HWP-053) is a commercial-grade engine cooling system component engineered specifically for Hino 700 Series, Super Dolphin Profia heavy commercial transport trucks, prime movers, and Kobelco heavy hydraulic excavators powered by Hino P11C, P11C-T, and P11C-U (10.5L / 10,520cc) 24-valve inline-6 common-rail turbocharged diesel engines (Hino 700 SH1E, SS1E, FS1E, FR1E, FN1E, FW1E, FY1E, FM2P heavy prime movers, multi-axle tippers, dump trucks, concrete mixers, and Kobelco SK460-8, SK480-8, SK500LC-8 excavators). Built in the pulley-driven configuration, this heavy-duty cast iron water pump features a pre-installed 4-hole threaded pulley/fan mounting flange hub with a stepped pilot collar, a pre-assembled 3-screw steel rear backing cover plate, dual rear-facing 2-bolt oval coolant flange ports, a press-fitted silver metal hose connection spout, and an auxiliary front-side flange port. Replacing a worn, noisy, bearing-seized, or leaking water pump restores continuous, high-volume coolant circulation through the engine block, oil cooler, and radiator, preventing severe overheating and head gasket failure under extreme payloads and heavy excavation duties.

Key Dimensions & Features (As Shown in Product Photos)

• Top Pulley / Fan Hub Configuration: Pre-installed CNC-machined steel mounting flange featuring 4 threaded bolt holes, a precision stepped pilot register collar, and a center pilot cap/shaft end for concentric pulley and fan clutch alignment.

• Pre-Assembled Steel Rear Cover Plate: Supplied complete with a factory-sealed zinc-plated steel rear backing cover plate fastened by 3 countersunk Phillips screws and sealed with an internal gasket.

• Multi-Port Cast Iron Volute Body:

  • Dual Rear-Facing 2-Bolt Oval Flange Ports: Features 2 CNC-machined 2-bolt oval coolant flange ports (one upper port and one lower port located on the extended rear manifold arms).

  • Metal Hose Connection Spout: Left-hand arm features a press-fitted unpainted silver metal hose sleeve/spout for radiator hose coupling.

  • Front-Side Flange Port & Mounting Bosses: Lower front casting features a vertical 2-bolt oval flange / bracket mounting face and perimeter through-bolt mounting ears.

• Reinforced Casting: Heavy-duty black-coated cast iron body with external structural reinforcement ribs designed to absorb heavy serpentine belt tension and engine vibration.

• Visual Verification Notice: Key structural details including the 4-hole threaded top hub, stepped pilot collar, unpainted metal hose spout, dual rear 2-bolt oval ports, and 3-screw steel rear cover plate are shown directly in our product photos.

• Please verify your existing water pump drive style (pulley hub vs. shrouded gear) and dual rear oval port layout against our product photos before ordering.

• (Note: Hino P11C engines use two distinct water pump drive systems: gear-driven P11C models use a shrouded timing gear pump [16100-3910 / 16100-3771 / 16100-3781], whereas pulley-driven P11C models use this 4-hole flange hub water pump [16100-E0490 / 16100-4120 / 16100-3811 / HWP-053] featuring dual rear 2-bolt oval flange ports and a 3-screw steel backing plate. Always confirm whether your engine uses a belt-driven pulley hub or timing drive gear prior to ordering.)

Why Choose Our Commercial Truck Parts?

• Pre-Installed 4-Hole Threaded Flange Hub: Factory-pressed, CNC-machined steel hub with 4 tapped mounting holes and stepped register ensures true pulley concentricity and eliminates belt runout or vibration under high RPM.

• Pre-Assembled 3-Screw Steel Rear Cover Plate: Comes factory-sealed with its zinc-plated backing plate and internal gasket to eliminate rear cover coolant leaks and save workshop installation time.

• Precision-Machined Dual Oval Ports & Metal Spout: Flat-machined 2-bolt oval flange faces and a press-fitted steel hose sleeve ensure a tight, leak-free connection across all P11C cooling passages.

• Heavy-Duty High-Capacity Bearing & Mechanical Seal: High-grade sealed bearing assembly paired with a wear-resistant silicon carbide/carbon shaft seal withstands continuous belt tension and high cooling system pressures without developing shaft play or coolant weepage.

• Ready Stock & Fast Shipping: Readily stocked for quick dispatch.
