The cylinder head is the lid of the combustion chamber and the single most stressed casting on a diesel engine. On the Weichai WD615 and WP10 family it carries the intake and exhaust ports, the valve train, the injector seats and the water jackets that keep combustion temperatures under control. Part number 61560040040 is the complete bare head used across the six-cylinder WD615 and WP10 platforms, the engines that power a very large share of the HOWO, Shacman and Steyr-derived trucks still working in Africa, Central Asia, Southeast Asia and Latin America.
Because the head sees constant thermal cycling, it is also the part most often replaced during an overhaul. A crack between valve seats, a warped deck or worn valve guides will show up as coolant loss, white smoke or a misfire that no amount of injector tuning will fix. Replacing the head with a correctly machined casting restores compression, stops coolant from entering the cylinders and brings oil consumption back to normal.
The 61560040040 head is fitted to naturally aspirated and turbocharged versions of the WD615 series and to the WP10 series that succeeded it. Typical applications include:
Because the same casting serves several ratings, buyers should always confirm the engine nameplate and the original part number before ordering. If you are not sure, send us a photo of the engine plate and the old head; we will cross-check the casting number and valve arrangement for you.
Each head is produced from a high-grade grey iron casting that matches the original Weichai metallurgy. After casting, the deck is machined flat, the valve seats and guides are cut, and the injector bores are reamed to the correct depth. Our supply is checked on three points before packing:
Heads are shipped assembled with valves and springs where possible, protected with anti-rust oil and packed in a foam-lined carton that survives long ocean transit. If you prefer a bare head for your own valve work, tell us before the order ships.
Diesel heads rarely fail without warning. The most common symptoms reported by workshops running WD615 and WP10 engines are:
Any of these symptoms should be followed by a pressure test of the cooling system and, if needed, a head-off inspection. Continuing to run an engine with a cracked head usually turns a head replacement into a full overhaul.
Fitting a new head is straightforward if the preparation is done properly. We recommend the following sequence:
If the head is supplied bare, have the valve seats cut and the guides checked by a machine shop before assembly. Do not lap valves into an unmachined seat.
The 61560040040 casting is often requested together with the full gasket kit, the head bolt set and the valve cover gasket. Ordering them together saves freight and avoids mismatched parts. Common cross references include the original Weichai number 61560040040 and the equivalent industrial WP10 head used on generator sets.
If your engine has been rebuilt before, check whether the head on the truck is a later WP10 casting. The two look similar but differ in port shape and injector bore depth, and mixing them causes poor performance and hard starting.
Most head failures come from cooling system neglect rather than casting defects. Keep the coolant mixture within specification, replace the water pump and thermostat at the recommended intervals, and never run the engine with a failed fan clutch. Watch the exhaust gas recirculation and aftercooler circuits for blockages; a restricted aftercooler raises intake temperature and puts extra thermal load on the head.
It is the same family casting. The WD615 and WP10 share the basic head design, but always confirm the engine plate and the old casting number because injector bore depth and port shape changed between production years.
Yes by default. We can also supply a bare head if your workshop prefers to fit its own valve train.
No. WD615 and WP10 head bolts are torque-to-yield and must be replaced every time the head is removed.
Stock items leave our warehouse within 3 to 5 working days. Sea freight to Africa and Latin America typically takes 25 to 40 days depending on the port.
