HINO 700 PROFIA SH1E FS1E FR1E SS1E FM2P SK460-8 SK480-8 P11C P11C-T P11C-U 10.5L OD 98MM 40MM 4-HOLE HUB ENGINE COOLING WATER PUMP ASSY WITH BACK PLATE (OE: 16100-4120 / 161004120 / S1610-04120 / 16100-3811 / 16100-3311 / 16100-3611 / 16100-E0490 / HWP-053)

Overview

The Hino 700 / Profia P11C Pulley-Hub Type Engine Water Pump Assembly (Water Pump Assy 16100-4120 / 161004120 / S1610-04120 / 16100-3811 / 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. Unlike the timing-gear-driven P11C water pump variants, this pulley-driven P11C configuration is built with a pre-installed 4-hole threaded pulley/fan mounting flange hub (98mm outer diameter with a 40mm stepped pilot collar), a pre-assembled 3-screw zinc-plated steel rear backing cover plate, an unpainted metal hose connection spout, dual rear 2-bolt oval coolant flange ports, and a top-facing 2-bolt small oval bypass port. Replacing a worn, noisy, bearing-seized, or leaking water pump restores continuous, high-volume coolant circulation through the cylinder block and radiator under heavy commercial haulage and excavation workloads.

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, 98mm flange outer diameter, a 40mm stepped pilot register collar, and a protruding center shaft end.

• Pre-Assembled Steel Rear Cover Plate: Supplied complete with a 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:

  • Rear Dual 2-Bolt Oval Flange Ports: Features 2 rear-facing machined 2-bolt oval coolant ports (one large oval port on the upper volute chamber and one oval port on the lower extended arm).

  • Front / Upper Small Oval Port: Extended side arm includes a top-facing machined 2-bolt small oval flange port with 2 threaded bolt holes.

  • Metal Hose Spout & Side Port: Opposite side features a press-fitted unpainted silver metal hose connection sleeve/spout alongside a vertical 2-bolt small side flange port.

• Auxiliary & Perimeter Mounting Bosses: Equipped with a raised female threaded boss on the elongated volute arm and perimeter through-bolt mounting bosses around the cast iron casing.

• Measurement Notice: Key specifications including the 98mm top hub outer diameter, 40mm stepped pilot collar, 4-hole threaded hub, 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 top flange diameter (98mm), pilot step (40mm), and multi-port body layout against the measurements shown in our photos before ordering.

  • YY: HWP-053 / HWP053

• (Note: Hino P11C engines use two distinct water pump drive designs: gear-driven P11C models use a shrouded drive gear [16100-3910, 16100-3771, 16100-3781], whereas pulley-driven P11C models use this flanged hub water pump [16100-4120 / S1610-04120 / 16100-3811 / HWP-053] with a 98mm / 40mm 4-hole top hub. Furthermore, compare the rear port layout carefully against K13C-TV pulley pumps [16100-3671], as this P11C 16100-4120 features two 2-bolt oval ports on the rear side and a zinc-plated 3-screw backing plate.)

Why Choose Our Commercial Truck Parts?
