HOWO Engine Parts – WD615, MC11, MC13 and WP Series Spare Parts

This page collects the HOWO engine parts we keep in stock or source regularly for overseas workshops and fleets – the parts that actually fail on WD615, MC11 / MC13 and Weichai WP series engines fitted to HOWO A7, T7H, TX and T5G trucks.

Every listing carries the factory part number (VG, AZ or 6-prefix Weichai numbers), so you can match it against your parts book or send us the number from the old component and get a quote the same day.

What this range covers

Top-end and gasket sets, cylinder liners and piston kits, crankshaft and connecting rod bearings, injection pumps and injectors, fuel metering units, oil and water pumps, turbochargers, engine mounts, ECUs and sensors. If a part is not listed, ask – we buy from the same Jinan supply chain that serves the domestic HOWO dealers.

Common failure points on HOWO engines

Liner cavitation and coolant loss on high-mileage WD615 units, injector wear that shows up first as rough idle and black smoke, and turbo bearing play after long intervals at high load. When a customer reports one of these, we usually quote the related gasket and fastener set at the same time, because reusing old hardware is the most common cause of a repeat repair.

Part numbers and ordering

HOWO engine numbers normally start with VG (Sinotruk engine group) or AZ (assembly), while Weichai engine components use six- or twelve-digit numbers, often with a Bosch cross-reference for fuel system parts. Send your engine plate photo and we will confirm the correct variant before you pay – the same engine family can carry two or three different injector part numbers depending on emission stage.

Part numbers in this range

45 part numbers listed. Send us your part number for a quote within 24 hours.

How to order

We confirm availability and price within 24 hours on working days, and send photos of the actual part before it leaves the warehouse. Payment by T/T or Western Union; shipping by air express for urgent items and by sea or rail for volume orders.
