Model: WP6
Part Number: 13032095
Brands: Weichai Power
Engine Model: WP6, WP6G, WP6H
Engine Type: Diesel
Scope of application: light and medium trucks, buses, agricultural machinery, generator sets
Rebuilding a diesel engine from individually ordered parts means matching pistons to liners, rings to pistons and gaskets to the exact cylinder head casting. Every mismatch is a potential oil burner or a leak. The Weichai WP6 overhaul kit 13032095 removes that risk by grouping the parts that wear together: pistons, rings, liners and the gasket set needed to close the engine again.
For workshops in export markets, the kit also solves a practical problem. One part number, one freight charge and one customs line instead of eight separate purchases that may not all arrive before the truck goes back into service.
Tell us the engine serial number and, if possible, the old piston number when ordering. WP6 engines were built in several ratings, and the compression ratio changed between some variants.
The WP6 is the four and six-cylinder mid-range engine used in light and medium trucks, buses, agricultural equipment and small generator sets. It is a popular unit in Africa, Southeast Asia and Latin America because it is simple, durable and easy to service. In overhaul terms it usually needs attention between 300,000 and 500,000 kilometres depending on duty and filtration.
Before ordering a kit, confirm the diagnosis. A worn turbo or leaking injectors can imitate a worn engine and cost far less to fix.
Three details decide the fit: engine model, compression ratio and the cylinder head casting. A kit for an early WP6 may not match a later head because injector bore depth changed. Send photographs of the engine plate and the old piston crown, and our team will confirm the variant.
After a rebuild the rings need load to seat properly. Avoid long idling, vary engine speed and apply moderate load in the first hours of running. Change the oil and filter after the initial period, then check head bolt torque, valve clearance and coolant level after the first heat cycle.
Clean air and correct oil decide how long the new parts last. Replace the air filter at interval, keep intake hoses sealed and use the specified oil grade. Keep the cooling system at the correct concentration to prevent liner pitting, and fix any oil or coolant leak immediately rather than topping up.
Individual parts can be cheaper on paper when only one cylinder needs attention. In practice, a WP6 that has worn one liner has usually worn all of them to a similar degree. Mixing one new liner with five worn ones produces uneven compression, uneven oil control and a rough running engine, and the second rebuild follows within a year.
A complete kit also guarantees that pistons, rings and liners were produced to match each other. When parts are bought separately from different suppliers, bore finish and ring tension can be slightly different, and the resulting oil consumption is very hard to diagnose afterwards.
Kits are heavy but compact. Pistons and liners are packed in separate foam-lined boxes inside one carton so that liners cannot chip each other, and the gasket set is packed flat to keep the head gasket uncreased. Tell us whether the kit will be consolidated with other parts so we can plan the load and reduce shipping volume.
The standard kit covers pistons, rings, liners and gaskets. Main and rod bearings are ordered separately to match the crankshaft size.
Only if the deck is flat and the bores are within specification. Have both checked before assembly.
Yes, the gasket set includes the head gasket for the matching head casting.
Usually three to five working days for an experienced workshop, including cleaning and measurement.
Browse the Weichai engine overhaul kit category, and pair the kit with the WP6 camshaft 13031471 or the WP6 cylinder head 13028584.
