Model: WP13
Part Number: 1000721713
Brands: Weichai Power
Engine Model: WP13, WP13.480, WP13.500, WP13.550, WP13.580
Engine Type: Diesel
Scope of application: heavy haulage trucks, mining dump trucks, construction machinery, generator sets
As ratings rose through the WP13 range, the cylinder head had to carry higher firing pressures and more heat through the same package size. Part 1000721713 is the head used on these high-output variants, with a deck and water jacket designed for continuous full-load operation in mining haul trucks and long-distance tractor units.
The head is the interface between combustion and everything around it: it seals the bore, routes coolant around the injector and valve bridges, and holds the valve train in alignment. Any weakness in the deck, the seat area or the injector bore turns into coolant loss, compression loss or a misfire that no injector change will cure.
The 1000721713 casting is fitted to WP13 engines in heavy trucks and industrial equipment. Applications include HOWO and Shacman tractor units, 8x4 mining dump trucks, large loaders and 300 to 500 kVA generator sets. It is not interchangeable with the earlier WP13 head 612700040030; the injector bore and coolant outlet positions differ, so match the casting number before ordering.
Every head is cast in high-grade iron, stress relieved and machined. The checks that matter most for reliability:
Heads are shipped assembled with valves and springs unless a bare unit is requested, oiled on machined faces and packed in a foam-lined carton suitable for sea freight.
Confirm with a cooling system pressure test and a combustion gas test before stripping the head. Both take minutes and prevent unnecessary work.
Never reuse torque-to-yield bolts, and never add sealant to a steel head gasket. Both mistakes cause uneven clamping and repeat failures.
Identify the engine by the plate on the block and the casting number on the old head. High-output variants can share the same external dimensions as lower-rated ones while differing internally. Send us both numbers and a photo of the injector seat, and our team will confirm the correct part before shipping.
Cooling is the dominant factor. Keep the correct coolant concentration, replace the water pump and thermostat on schedule, clean the radiator externally in dusty operations and check the aftercooler for restrictions. A head that runs hot will warp regardless of how well it was made.
A cylinder head is delicate on its deck and valve faces, so packing is part of the product. Heads are fixed to a timber skid, with the deck covered and the valve train protected, then banded so nothing moves in transit. Cartons are marked with lifting points and a this-way-up symbol.
If you are consolidating the head with a block in one container, tell us in advance so we can load the heavy items first and pack smaller parts around them. Stock sizes normally leave our warehouse in three to five working days, and sea freight to Africa, the Middle East and Latin America typically takes twenty-five to forty days depending on the port.
Yes, complete with valves, springs and retainers unless you request a bare head.
No. They are torque-to-yield and must be replaced each time the head is removed.
Check the casting number on the existing head and the engine plate. The two heads are not interchangeable.
Usually an incorrect seat depth or a worn washer seat. Both are checked on every head we supply.
See the Weichai cylinder head category, and complete the top end with the WP13 cylinder liner 612700010010 or the WP13 cylinder block 612700010001.
We offer OEM quality and excellent after-sales service as a complementary option. Engine brands supported include Weichai, Baudouin, Yuchai, Caterpillar, FAW Xichai, Sinotruk, Cummins and other engine parts. Specifically engine overhaul kits, pistons, cylinder liners, crankshafts, camshafts, fuel pumps, water pumps, lube pumps, injectors, and other performance parts.
If you are not sure about the part number that you need, please provide all the information you have, such as the equipment nameplate, engine nameplate or engine number, or real photos.
