Model: WP7 / WP8
Part Number: 610800040023
Brands: Weichai Power
Engine Model: WP7, WP7H, WP8, WP8H
Engine Type: Diesel
Scope of application: medium and heavy trucks, buses, construction machinery, generator sets
A full gasket kit is the complete sealing package for an engine rebuild. Kit 610800040023 for the Weichai WP7 and WP8 includes the multi-layer steel head gasket, valve cover gasket, intake and exhaust manifold gaskets, oil pan gasket, front and rear crank seals, water pump and thermostat housing seals, injector copper washers and the small O-rings used across the engine.
Buying the whole set costs less than assembling the parts individually, and more importantly it guarantees that every sealing surface is renewed at the same time. Reusing an old manifold or pan gasket after a rebuild is the most common reason a fresh engine begins to leak within the first thousand kilometres.
The kit covers WP7, WP7H, WP8 and WP8H engines in trucks, buses, wheel loaders and generator sets. Because these engines share a common block architecture, one kit serves a wide spread of ratings. Confirm the engine plate and, if possible, the old gasket number before ordering, especially if the engine has been rebuilt before with a later head casting.
Gaskets are only as good as their materials, and this is where cheap kits fail. This set uses multi-layer steel for the head gasket with an elastomer coating that conforms to minor deck imperfections, reinforced composite for oil pan and timing cover flanges, annealed copper washers for injectors and banjo fittings, and heat-resistant rubber lip seals for the crank ends.
Kits are packed flat in a rigid carton so the head gasket cannot be creased in transit. A creased gasket will leak even when fitted perfectly.
Workshops usually see one or more of these before ordering a full kit: oil weeping from the pan rail or rear main area, coolant seeping at the water pump, soot marks around manifold joints with a whistling noise under load, bubbles in the radiator, or oil and coolant mixing.
If the head gasket has failed, check deck flatness on both head and block before fitting the new kit. A new gasket on a warped deck fails again within a few thousand kilometres, which is why the head must be checked at the same time.
Three numbers decide the fit: engine model, model year and the head casting currently fitted. A kit for an early WP7 may not suit a later head because coolant passage and injector bore layouts changed. Send the engine plate photo and the old gasket number and we will confirm before shipping.
Store the kit flat and dry, away from sunlight. Composite gaskets slowly absorb moisture, so a kit that has been stored in a damp workshop for years should be inspected before use. Keep the head gasket in its carton until the deck is ready, not lying on a bench where it can be bent.
Kits are light and compact, which makes them ideal for consolidating with heavier parts such as liners or pistons. Tell us what else is going into the shipment and we will pack the kit on top so it is not crushed by a cylinder block.
New gaskets settle over the first few hundred hours. Retorque manifold bolts and check pan bolts after the first week, keep the coolant at the correct mixture to prevent liner pitting and repair any oil leak immediately, because oil soaking into a composite gasket eventually softens it.
