Product Overview
The QDJ2845C-series starter motor (OE QDJ2845C, 612600091077, 612630030011, 0001261015) is an OE-spec replacement starting component built for Weichai WD615 and WP12 heavy-duty diesel engines. Rated at 24V 8KW with an 11-tooth drive pinion, this brand-new starter delivers high cranking torque so your heavy truck, bus or construction machine starts reliably every time, even after sitting overnight on a cold site.
This aftermarket unit matches the original starting-system requirements of Weichai WD615 / WP12 power units working under tough haulage and job-site conditions. It adopts a heavy-duty solenoid switch and reinforced gear assembly to cope with frequent cold-cranking in low-temperature, high-dust environments. The unit is stocked in-house, backed by a 1-year warranty with a 10-day dispatch lead time. High cranking-torque design guarantees reliable cold-start performance for 24V diesel powertrains.
Key physical specs: net weight 9.35 kg, gross weight 9.85 kg, overall dimensions 440 x 240 x 190 mm, supplied in a neutral kraft inner carton.
Weichai WD615 / WP12 Engine and 24V Starting System
Weichai WD615 and WP12 inline-six heavy-duty diesel engines are widely fitted to Chinese heavy trucks, large buses, wheel loaders and other construction machinery. These high-displacement diesel units require high-torque 24V starting equipment rather than light-vehicle 12V starters, so a correct voltage match protects your whole electrical system.

Engine Compatibility and Cross Reference
This starter motor fits heavy-duty equipment equipped with Weichai WD615 and WP12 diesel engines. Do not rely solely on vehicle model for fitment validation; always verify the engine model, old-starter OE number, pinion tooth count and power rating stamped on your original starter housing.
| Equipment Type | Engine Model | Typical Applications |
|---|---|---|
| Heavy-duty truck | WD615 | Sinotruk Howo, Steyr heavy truck |
| Heavy-duty truck | WP12 | Shacman, FAW heavy-duty commercial vehicle |
| Construction machinery | WD615 / WP12 | Wheel loader, mixer truck, engineering machinery |
Multiple OE numbers exist across different production batches for this same starter family. If your original starter housing carries any one of the listed part numbers, the QDJ2845C-series unit is a direct drop-in replacement.
What to Look for in a Replacement
Follow these five verification steps before placing your order to avoid wrong-part returns:
1. Check the nameplate data on your old starter: confirm the rated power is 8KW @24V. Different voltage or power ratings are not interchangeable.
2. Count the pinion teeth: this unit requires 11T. An incorrect tooth count will destroy the flywheel ring gear.
3. Confirm your engine is Weichai WD615 / WP12 diesel. Other Weichai engine families use different starter assemblies.
4. Match the OE / reference part numbers stamped on your original starter housing.
5. Weight cross-check: a genuine matching unit weighs about 9.35 kg net; a significant weight difference indicates the wrong assembly or low-grade build quality.
Application Scenarios
Independent heavy-duty repair shops and Weichai-specialized workshops servicing WD615 / WP12 trucks, buses and construction machinery across Asia-Pacific, Africa, Middle East and Latin-American markets.
Parts counters and jobbers stocking Chinese heavy-duty starting and charging electrical components for trucks and off-road machinery.
Fleet operators maintaining original-spec heavy-duty commercial vehicle fleets.
Used heavy-truck export traders supplying second-hand Chinese commercial vehicles to global secondary markets.
Machinery maintenance teams restoring construction equipment to factory-standard condition.
FAQ
Q: Does this starter fit both trucks and construction machinery?
A: Yes. The QDJ2845C-series covers trucks, large buses and engineering machinery fitted with Weichai WD615 or WP12 diesel engines.
Q: My old starter shows OE number 612630030011 or 0001261015. Will QDJ2845C work?
A: Yes. These OE numbers belong to the same starter family, differing only by production revision and market specification, so the QDJ2845C-series unit serves as a direct replacement.
Q: What is the normal cranking voltage for a 24V system?
A: Under cranking condition, battery terminal voltage should stay above 20V. If voltage drops sharply below 18V during cranking, inspect battery health, battery cables and ground connections rather than only the starter itself.
Q: Can I install this unit for extremely frequent cold-start operation in very cold regions?
A: This is a stock-spec 8KW starter for standard working conditions. For extreme low-temperature sites with heavy repeated cranking duty, consider a high-torque upgraded starter solution.
Q: What is your warranty and lead time?
A: Goods are in stock with a 10-day dispatch lead time. A 1-year warranty applies from installation date; it excludes damage caused by mis-installation, flywheel ring-gear damage, poor cable connections or vehicle electrical-system faults.
In Practice
For technicians working on Weichai WD615 / WP12 heavy-duty platforms: before removing the existing starter motor, perform starting-system diagnostics. Measure battery terminal voltage under cranking load. Defective batteries, corroded heavy-duty cables, bad ground points or damaged flywheel ring gear can mimic starter-failure symptoms, so do not replace the starter blindly. Always disconnect battery terminals before commencing removal work.
Take photos of wiring terminals and bolt positions during disassembly to avoid mis-wiring during reassembly. Inspect the flywheel ring gear for chipped or worn teeth before fitting the new starter, because a damaged ring gear will quickly destroy the new starter pinion. Tighten mounting bolts to the manufacturer's official workshop-manual torque specifications.
