Model: WD615 / WP10
Part Number: 612600040355
Brands: Weichai Power
Engine Model: WD615, WD615E2, WD10, WP10, WP10G
Engine Type: Diesel
Scope of application: heavy trucks, buses, construction machinery, generator sets
A full gasket kit is the difference between an overhaul that stays dry and one that weeps oil from every joint. The Weichai 612600040355 set is the complete upper and lower engine sealing package for the WD615 and WP10 six-cylinder diesel. It contains the cylinder head gasket, valve cover gasket, intake and exhaust manifold gaskets, oil pan gasket, front and rear crank seals, water pump and thermostat housing gaskets, injector seat seals and the small copper washers used across the engine.
Buying the complete kit instead of individual gaskets saves money and, more importantly, guarantees that every sealing surface is renewed at the same time. Reusing an old manifold or oil pan gasket after a rebuild is the most common cause of oil leaks that appear within the first thousand kilometres.
The 612600040355 kit is specified for the six-cylinder WD615 series and the WP10 series that replaced it. Practical applications include HOWO and Shacman heavy trucks, city buses with WD615.47 engines, wheel loaders and excavators using the WD10 industrial version, and WP10 generator sets in the 80 to 250 kVA range. Because these engines share the same block architecture, one kit covers a wide spread of ratings.
Always confirm the engine serial number and, if possible, the old gasket part number before ordering. Engines that have been rebuilt with a later WP10 head may need the matching head gasket variant, which we can supply separately.
Gaskets are only as good as their materials. This kit uses:
Every kit is checked against the original Weichai parts list so that no washer or O-ring is missing. Kits are packed flat, labelled by position and shipped in a rigid carton to avoid creasing the head gasket in transit.
Workshops usually see one or more of these before ordering a full kit:
If the head gasket has failed, check the head and block deck for flatness before fitting the new kit. A new gasket on a warped deck will fail again within a few thousand kilometres.
Three numbers matter: the engine model, the model year and the head casting currently fitted. A kit that suits an early WD615 may not fit a later WP10 head because the coolant passage layout changed. If you are unsure, send us the engine plate photo and the old gasket number; we will confirm before shipping.
For workshops doing regular WD615 overhauls, keeping one complete kit on the shelf shortens downtime considerably. The kit is light, does not expire and takes very little storage space.
New gaskets seat over the first few hundred hours of operation. Retorque the manifold bolts and check the oil pan bolts after the first week. Keep the cooling system filled with the correct mixture to prevent liner pitting, and fix any oil leak immediately, because oil soaking into a composite gasket eventually softens it.
Yes. 612600040355 is a full set and includes the cylinder head gasket, all manifold gaskets, the oil pan gasket, crank seals and the small sealing washers.
Yes, the WP10 industrial engine uses the same sealing layout. Confirm the head casting number if the engine has been rebuilt before.
No. The multi-layer steel head gasket is designed to be installed dry. Extra sealant can cause uneven clamping and premature failure.
No. Gaskets and copper washers are single-use items and must be replaced each time a joint is opened.
