Model: WD615 / WP10
Part Number: 612600061364
Brands: Weichai Power
Engine Model: WD615, WD615E2, WD10, WP10, WP10G
Engine Type: Diesel
Scope of application: heavy trucks, buses, construction machinery, generator sets
Diesel engines convert roughly a third of their fuel energy into useful work; the rest becomes heat. On the Weichai WD615 and WP10 the coolant circuit has to remove that heat continuously, and the water pump is what keeps the coolant moving. Part 612600061364 is the standard pump for these six-cylinder engines, driven by belt from the crankshaft and sealed against the block with a gasket and O-ring.
When the pump weakens, the first symptom is usually not a leak but overheating under load: the engine is fine at idle and climbs in temperature on a long gradient or at full throttle. Because the head and liners of the WD615 are sensitive to heat, a pump that is allowed to fail slowly can turn into a warped head or a blown gasket.
The pump suits naturally aspirated and turbocharged WD615 engines and the WP10 series that followed. Typical installations include HOWO and Shacman trucks, city and intercity buses, wheel loaders and excavators with the WD10 industrial engine, and generator sets in the 80 to 250 kVA range. Marine derivatives of the WD615 use a similar pump with a different pulley arrangement, so the engine plate should always be checked before ordering.
The pump is built around a cast iron housing with a precision-cast impeller, a sealed ball bearing cartridge and a mechanical face seal. Production checks cover:
Each pump is fitted with a new gasket and O-ring and shipped with the pulley flange protected. The bearing cartridge is sealed for life, so no greasing is required or possible.
Do not ignore a noisy pump. Once the bearing collapses, the fan can hit the radiator and the repair cost multiplies.
612600061364 covers the common WD615 and WP10 applications, but industrial and marine versions differ in pulley and inlet position. If your engine has been swapped or rebuilt, compare the old pump casting number with the new one before fitting. When in doubt, send a photo of the old pump and the engine plate and we will confirm.
For workshops, the pump is a fast-moving item. Keeping one in stock avoids delaying a truck for a part that costs far less than a day of downtime.
The pump lasts longest in a clean system. Flush the radiator at the recommended interval, use a 50/50 coolant mix with the correct inhibitor package, and replace the thermostat and pressure cap when they are due. A stuck thermostat makes the pump work against a closed circuit and shortens seal life, while a weak cap allows the coolant to boil at a lower temperature.
Yes, both are included. We recommend replacing the thermostat housing gasket at the same time.
Only to reach a workshop. Coolant loss quickly leads to overheating, and overheating on a WD615 can warp the head.
The pump is supplied with the hub but without the pulley unless requested. Tell us if you need the complete assembly.
Remove the belt and spin the pump by hand. Roughness or play confirms a bearing problem rather than belt slip.
