HINO RANGER FD3H GD3H FF3H FG3H EX220-5 H07CT H07C H07D 6.7L 7.4L 28.5MM SHAFT 8-HOLE BASE 8-VANE HEAVY DUTY ENGINE COOLING WATER PUMP ASSY (OE: 16100-3592 / 161003592 / 16100-3264 / 161003264 / S1610-03592 / HWP-048)

Overview

The Hino H07CT / H07C Heavy-Duty 8-Hole Engine Water Pump Assembly (Water Pump Assy 16100-3592 / 16100-3264 / HWP-048) is a commercial-grade engine cooling system component engineered specifically for Hino Ranger medium-to-heavy commercial transport trucks and heavy construction excavators powered by Hino H07CT (6.7L Turbo), H07C (6.7L), H07CT-EX, and H07D (7.4L) inline-6 direct-injection diesel engines (Ranger FD, GD, FF, FG, FC, GH series commercial cargo lorries, tippers, dump trucks, and Hitachi EX220-5 hydraulic excavators). Built in the heavy-duty open-impeller cartridge style, this cast iron water pump features a 28.5mm drive shaft with a top hex locking nut, an exposed circlip-retained top bearing assembly, an 8-hole mounting flange base, dual grease fittings, and an 8-vane open cast iron impeller. Replacing a worn, noisy, bearing-seized, or leaking water pump restores high-volume coolant circulation through the engine block and oil cooler, preventing overheating under continuous commercial haulage and excavation workloads.

Key Dimensions (As Labeled in Product Photos)

• Drive Shaft & Bearing Configuration: Precision-machined 28.5mm shaft diameter fitted with a top hex locking nut and washer, supported by a heavy-duty exposed top ball bearing retained by an internal snap ring (circlip).

• Mounting Base Configuration: 8-hole perimeter mounting flange base (4 raised machined bolt bosses and 4 lower flange mounting holes) with a flat CNC-machined rear sealing surface that mounts directly into the engine block / timing case water cavity.

• Lubrication Design: Equipped with 2 grease fittings (grease nipples) on the lower housing perimeter bosses for periodic bearing lubrication and maintenance.

• Impeller Design: Heavy-duty cast iron 8-vane (8-blade) open impeller on the rear cavity engineered for high-volume coolant displacement.

• Measurement Notice: Key specifications including the 28.5mm shaft diameter, 8-hole mounting base layout, dual grease fittings, and 8-vane open rear impeller are shown directly in our product photos.

• Please verify your existing water pump shaft diameter (28.5mm) and 8-hole mounting base pattern against the measurements shown in our photos before ordering.

• (Note: Late-model 8-hole Hino H07CT / H07C / H07D water pumps share the same 8-hole open-impeller base but differ at the top shaft: 16100-2971 [HWP-026] comes with a pre-installed 4-hole threaded pulley flange hub, whereas this heavy-duty 16100-3592 / 16100-3264 [HWP-048] features a bare 28.5mm shaft with a top hex nut and 2 grease nipples. Always check whether your old pump uses the 28.5mm nut-retained shaft prior to ordering.)

Why Choose Our Commercial Truck Parts?

• Heavy-Duty 28.5mm Shaft & Circlip-Retained Bearing: Oversized 28.5mm drive shaft and high-load ball bearing secured by an internal snap ring withstand heavy pulley/gear radial loads without shaft play or bearing wobble.

• Serviceable Dual Grease Fittings: Built-in grease nipples allow workshop mechanics and machine operators to lubricate the internal bearing assembly during scheduled servicing.

• High-Flow 8-Vane Cast Impeller: Precision-balanced 8-blade cast iron impeller maximizes coolant circulation across the cylinder block and oil cooler under sustained turbo-diesel operating loads.

• CNC-Machined 8-Hole Mounting Face: Flat-machined rear flange surface provides a flush, leak-free seal directly against the engine timing case.

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