The WP13 has more than one overhaul kit number, and 1008692189 is one of them alongside 1002347071. The difference between them is usually the piston specification and, in some cases, the gasket set that matches a particular head casting.
That matters because a kit from the wrong generation will assemble and run, but with the wrong compression ratio or a gasket that does not quite seal at the fire ring. Comparing the old piston crown and the old head gasket with the new kit before assembly is the quickest way to catch the mismatch.
This is a complete wearing-parts set rather than a partial collection. Every component normally replaced during a full overhaul is included, and the parts are matched to each other rather than drawn from different suppliers.
A WP13 usually signals its need for an overhaul through oil consumption and blow-by long before it loses power. Reading those signals early is what separates a planned rebuild from an emergency one at the roadside.
The order of assembly matters as much as the parts. Clean the block, check flatness and set liner protrusion before any piston goes in, because those measurements decide whether the new gasket will hold.
Match on the engine plate, the old piston number and the head casting. Where the engine has already been rebuilt, the piston in it may not be the original specification, so the old part is the better reference than the service book.
Send photographs of the old piston crown and the engine plate and our team will confirm the kit before shipping. Getting this check done at the ordering stage costs nothing; getting it wrong costs a second strip-down.
Individual parts look cheaper when only one cylinder needs attention, but an engine that has worn one liner has usually worn all of them similarly. Mixing one new liner with the rest produces uneven compression, and the second rebuild follows within a year.
Have the measuring tools ready before the engine comes apart: bore gauge, dial indicator, plastigauge, calibrated torque wrench and a straight edge. A rebuild without measurements is guesswork. New head and rod bolts should be on site as well, because both are single-use fasteners.
An overhaul is the right moment to service the cooling and fuel systems as well. Clean the radiator core, check the water pump, and have the injectors tested. A leaking injector is one of the common causes of the wear that prompted the rebuild, and leaving it in place means the new kit inherits the same problem.
Run at varying load after the rebuild, increasing gradually, and change oil early. Holding full load immediately glazes the bores and leaves the rings unseated, which is the most common reason a fresh engine burns oil.
Clean air and correct oil decide how long the new parts last. Replace the air filter at interval, keep intake hoses sealed, use the specified oil grade and fix any leak immediately rather than topping up.
Bearings and stretch bolts are not part of the kit because they depend on the crankshaft size and on the engine's condition. Order them at the same time as the kit so that everything arrives together; a kit waiting on a set of main bearings holds the whole rebuild just as effectively as a missing piston.
Compare the old piston crown and head casting, or send us photos.
No, bearings are ordered separately to match the crankshaft.
Yes, the gasket set includes the head gasket.

Weichai WP13 Piston (1008692189). This piston carries the combustion load and forms half of the combustion chamber. Its crown profile is matched to the rating, not just to the bore diameter.
Check the ring groove width with the old ring and a feeler gauge. An opened groove lets the new ring flutter, and a fluttering ring breaks.
The part number is the reliable identifier here. Where the old number is unreadable, measure the component and compare it with the drawing rather than guessing from the engine model. On this engine, confirm the WP13 application against the engine plate before ordering.
Clean the ring grooves to bare metal before fitting new rings. Carbon at the bottom of a groove holds the ring proud and produces the same blow-by as a worn bore.
Ordering note. Photographs of the actual unit can be sent before dispatch on request. That is the cheapest way to avoid a return when a casting revision is in doubt.
