Model: WP6
Part Number: 13026701
Brands: Weichai Power
Engine Model: WP6, WP6G, WP6H
Engine Type: Diesel
Scope of application: light and medium trucks, buses, agricultural machinery, generator sets
Kit 13026701 is the complete sealing set for a WP6 rebuild. It 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 full set costs less than assembling parts individually and guarantees that every sealing surface is renewed together. Reusing an old manifold or pan gasket is the most common reason a freshly rebuilt engine begins to leak within the first thousand kilometres.
The kit covers WP6, WP6G and WP6H engines in light and medium trucks, buses, tractors and generator sets. These engines work in dusty and hot conditions across Africa, Southeast Asia and Latin America, so sealing quality matters. Confirm the engine plate and, where possible, the old gasket number before ordering.
Gaskets succeed or fail on materials. This kit uses multi-layer steel for the head gasket with an elastomer coating that conforms to minor deck imperfections, reinforced composite for 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. A creased gasket leaks even when installed perfectly.
Before ordering, confirm which gasket has failed. Oil at the pan rail points to the pan gasket or rear main. Coolant at the front points to the water pump. Soot around manifold joints with a whistle under load points to manifold gaskets. Bubbles in the radiator 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.
Three details decide fit: engine model, model year and the head casting currently fitted. A kit for an early WP6 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.
The three most common 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.
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 use. Keep the head gasket in its carton until the deck is ready.
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.
On the WP6 the most common failure is the head gasket, followed by the manifold gaskets and then the rear crank seal. Each has a different signature: head gasket failures consume coolant and pressurise the cooling system; manifold failures show soot tracks and a whistle under load; rear seal failures leave oil at the bell housing rather than at the pan.
Identifying the actual failure matters because a complete kit is only worth fitting if the engine is being opened anyway. If only the valve cover gasket has failed, a full kit is unnecessary. If the head is coming off, the kit is the sensible purchase.
Yes. 13026701 is a full set with head gasket, manifold gaskets, pan gasket, crank seals and washers.
No. The WP7 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.
Browse the Weichai gasket set category, and pair the kit with the WP6 cylinder head 13028588 or the WP6 cylinder liner 13056682.
Weichai WP6 Full Gasket Kit (13026701). The gasket set seals combustion, coolant and oil at every joint opened during a top-end repair. The head gasket inside it is the component that decides whether the job holds.
Compare the old head gasket with the new one for fire ring position, coolant hole pattern and thickness. A gasket from the wrong generation bolts up and leaks at the fire ring.
Numbers beginning 1302 sit in the WP6 and early WP7 range. Fitment depends on the front-end arrangement rather than the nominal part type. On this engine, confirm the WP6 application against the engine plate before ordering.
Install the head gasket dry unless the manual says otherwise. Sealant prevents composite and MLS gaskets from seating correctly.
Ordering note. If the old number has been superseded, the replacement number is quoted alongside the original so the purchasing file stays consistent.
