Model: WP13
Part Number: 612700010007
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
A 13-litre diesel circulating oil through a turbocharger, piston cooling jets and a high-load valve train needs a lot of flow at pressure. Part 612700010007 is the gear-type oil pump for the Weichai WP13, driven from the front of the engine and fitted with an integrated relief valve. It must deliver enough volume at idle to keep the bearings supplied, and hold pressure at rated speed without exceeding the limit set by the relief valve.
When the pump wears, the first sign is not usually a red light. It is a slow drop in oil pressure at hot idle, a rise in oil temperature and eventually a knock under load. Replacing the pump during an overhaul is inexpensive compared with replacing a crankshaft.
The pump fits WP13 road and industrial engines, including mining dump trucks, heavy tractor units, large loaders and generator sets. It is not interchangeable with the WP12 pump; the drive gear and pick-up arrangement differ. Confirm the engine plate and the old pump number before ordering.
Each pump is shipped oiled and plugged so that no dust enters the galleries. The drive gear is fitted and keyed as original.
Before replacing the pump, confirm pressure with a mechanical gauge at the main gallery and inspect the pick-up strainer. A blocked strainer imitates a worn pump exactly.
Match part number, engine rating and drive type. Industrial and marine WP13 variants sometimes use a different pick-up. If your engine has been rebuilt with a replacement front cover, check that the pump mounting face matches.
For fleets, keep a spare pump, gasket and O-ring on the shelf. Failure is rare but sudden, and a spare turns a two-week wait into an afternoon.
Contamination is the main killer. Use the specified oil grade, change it at the severe-duty interval and never run with a leaking injector that thins the oil with diesel. Keep the cooling system healthy too: sustained overheating thins oil and reduces film strength at the bearings.
Low oil pressure has several possible causes and the pump is only one of them. Work through the list in order: check the oil level and condition, replace the filter, inspect the pick-up strainer for a blocked mesh, verify pressure with a mechanical gauge at the main gallery, then test the relief valve. Only when those are ruled out should the pump come off.
If pressure is low only when hot, worn bearings are as likely as a worn pump. If pressure is low only at idle and recovers instantly with engine speed, the relief valve or the pump clearances are usually responsible. Recording pressure at three points, cold idle, hot idle and rated speed, gives a clear diagnosis and avoids unnecessary parts.
Yes, the mounting gasket and O-ring are supplied. Replace the pick-up O-ring at the same time.
Yes. A blocked strainer, stuck relief valve, worn bearings or a faulty sender all produce the same symptom. Test with a mechanical gauge first.
The pump comes with its drive gear fitted and timed as original.
At every major overhaul, or whenever the front cover is removed for another repair.
The pump body is the same, but the pick-up and drive details can differ on industrial and marine variants. Send the engine plate and the old pump number so we can confirm before shipping.
Browse the Weichai pump category, and complete the rebuild with the WP13 crankshaft 612700020003 or the WP13 cylinder block 612700010001.
We offer OEM quality and excellent after-sales service as a complementary option. Engine brands supported include Weichai, Baudouin, Yuchai, Caterpillar, FAW Xichai, Sinotruk, Cummins and other engine parts. Specifically engine overhaul kits, pistons, cylinder liners, crankshafts, camshafts, fuel pumps, water pumps, lube pumps, injectors, and other performance parts.
If you are not sure about the part number that you need, please provide all the information you have, such as the equipment nameplate, engine nameplate or engine number, or real photos.
