Model: WP13
Part Number: 1003217585
Brands: Weichai Power
Engine Model: WP13, WP13.480, WP13.500, WP13.550, WP13.580
Engine Type: Diesel
Scope of application: heavy haulage trucks, mining dump trucks, construction machinery, generator sets
The WP13 is a long-stroke 13-litre diesel that produces high torque from low engine speed. That combination puts heavy bending and torsional loads on the crankshaft. Part 1003217585 is the shaft used in this family, machined from forged alloy steel, induction hardened and nitrided, then ground to standard journal size.
The shaft carries the main and connecting rod bearings, drives the oil pump and camshaft through the gear train and transfers torque to the flywheel. Any loss of journal geometry shows up as oil pressure loss, knocking and, eventually, a spun bearing that destroys the rod and the journal together.
The shaft fits WP13 road and industrial engines. Typical installations are HOWO and Shacman heavy tractors, 8x4 mining dump trucks, large loaders and 300 to 500 kVA generator sets. Confirm the engine plate and the old crankshaft number: front pulley and flywheel flange details differ between some variants even when the main dimensions match.
Shafts are shipped in a braced crate with protective sleeves on the journals. If you need a specific undersize for a repair, tell us before dispatch; regrinding after delivery is rarely practical for export customers.
A knock is the last warning before a bearing spins. Once the rod bearing spins, the journal and the connecting rod are both lost.
Match the part number, the journal size and the bearing shells you intend to fit. Mixing a ground shaft with standard shells guarantees failure. Give us the bearing part numbers with your enquiry and we will confirm compatibility before shipping.
Lubrication and vibration control decide crankshaft life. Use the specified oil, change it at the severe-duty interval, keep the oil cooler clean and never run with a leaking injector that dilutes the oil. On engines that have suffered a hydraulic lock or a broken damper, check straightness before reuse.
The WP13 crankshaft is normally ordered together with main and rod bearing shells. Shells and journals are lapped to each other in service, so a shaft fitted with mismatched bearings fails quickly. Give us the engine serial number and the bearing part numbers you plan to use; we will confirm that the journal size matches before packing.
Early and late WP13 shafts differ in the front pulley fixing and, on some industrial variants, the flywheel flange. A shaft from a different variant may fit the block but will not accept your existing damper or flywheel. Photos of the old shaft ends resolve the question faster than any catalogue lookup.
A crankshaft is dense and awkward to handle, so it is bolted into a braced timber crate with sleeves over the journals. The crate is banded and marked with lifting points. Because freight is charged on both weight and volume, tell us whether the shaft will travel with a block in the same container; we can plan the load to reduce cost.
Standard shafts are usually available within three to five working days. Sea freight to Africa and Latin America takes twenty-five to forty days depending on the port, and air freight is available for emergency rebuilds at a higher rate.
Yes, journals and fillets are nitrided for wear and fatigue resistance.
It can if there is enough hardened layer left, but export customers usually prefer a new standard shaft.
Strongly recommended. A tired damper is a common cause of crankshaft failure.
Mount it on centres and measure run-out at the centre journal. Beyond specification means replacement.
Explore the Weichai crankshaft category, and complete the bottom end with the WP13 cylinder block 612700010001 or the WP13 oil pump 612700010007.
Weichai WP13 Crankshaft (1003217585). This shaft carries every firing impulse in the engine through six throws, and the journals are what maintain the oil film under that load. Ovality matters more here than nominal diameter.
Measure ovality at several positions along each journal, not at one point. A journal can read the correct diameter and still be oval by a few hundredths, which collapses the oil film twice per revolution.
Numbers beginning 1003 belong to the numeric series used across WP7, WP8 and WP9. The engine plate is the fastest way to confirm which revision applies. On this engine, confirm the WP13 application against the engine plate before ordering.
Fit a new torsional damper with the shaft. A perished damper sends the same oscillation into the new crankshaft and cracks it at the fillets.
Ordering note. Payment terms and shipping method are confirmed in writing before dispatch, including the port of loading and the estimated transit time.
