Model: WP7 / WP8
Part Number: 1001514985
Brands: Weichai Power
Engine Model: WP7, WP7H, WP8, WP8H
Engine Type: Diesel
Scope of application: medium and heavy trucks, buses, construction machinery, generator sets
This is the complete sealing set for a WP7 or WP8 rebuild. Inside the carton you get 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 assortment of O-rings used across the engine.
Assembling a rebuild from individual gaskets is slower and riskier. One missing washer means a leak that appears only after the engine is hot and loaded, and at that point the repair costs several times the price of the part that was forgotten. A complete kit removes that risk.
The set covers WP7, WP7H, WP8 and WP8H engines in trucks, buses, loaders, excavators and generator sets. These engines share a common block architecture, so one kit serves a wide range of ratings. Confirm the engine plate and, where possible, the old gasket number, particularly if the head has been replaced during an earlier repair.
Gaskets fail for predictable reasons: heat, pressure cycling and incompatible fluids. This kit addresses each. The head gasket is multi-layer steel with an elastomer coating that conforms to minor deck imperfections. Manifold gaskets use a composite with a metal core to survive exhaust temperature. Pan and timing cover gaskets are reinforced fibre, resistant to hot oil and coolant. Crank seals are heat-resistant rubber lip type.
Kits ship flat in a rigid carton so the head gasket cannot be creased. A creased gasket leaks even when fitted correctly.
Before ordering a kit, confirm which gasket has failed. Oil at the pan rail points to the pan gasket or rear main. Coolant at the front of the engine points to the water pump. Soot around the manifold joints with a whistling under load points to manifold gaskets. Bubbles in the radiator or oil in the coolant point to the head gasket.
If the head gasket has failed, check deck flatness on both head and block. A new gasket on a warped deck fails again within a few thousand kilometres, which is why the head should be checked at the same time as the kit is ordered.
Three details decide fit: engine model, model year and the head casting currently fitted. A kit for an early WP7 may not match a later head because coolant passages and injector bores changed. Send the engine plate photo and the old gasket number and we will confirm before shipping.
Store the kit flat, dry and out of sunlight. Composite gaskets slowly absorb moisture, so a kit stored in a damp workshop should be inspected before fitting. Keep the head gasket in its carton until the deck is ready rather than lying on a bench where it can be bent.
The three most common fitting mistakes are reusing the pan gasket after removing the pan, adding sealant to a steel head gasket and fitting manifold gaskets dry when the manual calls for a thin film. Each produces a leak that appears only when the engine is hot and working, when the repair costs far more than doing it correctly the first time.
Kits are light and compact, ideal for consolidating with liners, pistons or a block. Tell us what else is in the shipment so we can pack the kit on top and prevent it being crushed.
Retorque manifold bolts and check pan bolts after the first week. Keep 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.
Yes. 1001514985 is a full set with head gasket, manifold gaskets, pan gasket, crank seals and washers.
No. The WP6 uses different sealing parts. Ask us for the matching kit.
No. The steel gasket is installed dry.
No. Gaskets and copper washers are single-use.
