A WP13 rebuild is a significant investment in both parts and downtime, and assembling it from individually ordered components adds risk at every step. Kit 1002347071 groups the parts that wear together: pistons, rings, liners and the gasket set needed to close the engine again.
For fleets working in remote areas, the logistics matter as much as the technical match. One part number, one shipment and one customs entry is far easier than eight separate purchases where a single delayed item can hold the whole rebuild.
This is a complete wearing-parts set rather than a partial collection. Every component that is normally replaced during a full overhaul is included, and the parts are matched to each other rather than being drawn from different suppliers.
A WP13 usually announces 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.
Three details decide the fit: engine model, compression ratio and head casting. A kit from a different rating will physically assemble but produce the wrong compression ratio. Send photographs of the engine plate and the old piston crown and our team will confirm the variant.
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, and the engine will be back out of service sooner than expected. New head and rod bolts should be on site as well, because both are single-use fasteners.
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.
The piston is the part that changed between WP13 generations, because compression ratio and bowl design were revised alongside the injectors. Two kits can look identical in the carton and differ only in the crown, and the difference appears as smoke or poor economy once the engine runs.
If the old piston is available, compare it with the new one before assembly. If it is not, the engine plate and the head casting number usually resolve which generation the engine belongs to.
Write down every clearance, liner protrusion and ring gap in the engine log. The figures let the next overhaul compare wear rates, and they support any warranty discussion with the parts supplier. A rebuild without records means the next rebuild starts from zero.
The standard kit covers pistons, rings, liners and gaskets. Bearings are separate.
Yes, the gasket set includes the head gasket.
Only if the deck is flat and the bores are within specification.
Three to five working days for an experienced workshop.

Weichai WP13 Piston (1002347071). Heat and pressure both arrive at this component first. The ring grooves control oil and compression, and the bowl decides how efficiently the fuel burns.
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.
Numbers beginning 1002 are numeric-series numbers used mainly on WP8 and WP9 assemblies and castings. 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. Inspection reports can be provided for castings and crankshafts on request, covering the measurements taken before packing.
