Powerful, reliable engine cranking for heavy‑duty diesels – The OEM LG1611330001 Starter Assembly is a high‑torque, heavy‑duty starter motor engineered for SINOTRUK HOWO, SHACMAN, and other commercial vehicles. It delivers consistent, powerful cranking even in extreme cold, ensuring quick engine starts and minimizing downtime. Built with premium materials and precision components, this starter is designed for the harsh demands of long‑haul and off‑road operation.
This starter assembly features a robust solenoid, a high‑efficiency permanent magnet motor, and an overrunning clutch to prevent over‑crank damage. For guaranteed compatibility and reliable starting, always choose genuine Sinotruk Homan parts.
The LG1611330001 Starter Assembly is manufactured to original equipment specifications, ensuring a perfect fit on the engine block and correct engagement with the flywheel. Its advanced brush design and sealed housing provide long service life and resistance to dust, moisture, and temperature extremes.
The LG1611330001 Starter Assembly is built with a high‑torque series‑wound motor and a heavy‑duty solenoid. It produces cranking power of up to 4.5 kW (6.0 HP) at 12V, ensuring that even large‑displacement diesel engines start reliably in cold weather. The starter uses an overrunning clutch to prevent the motor from being driven by the engine after start, protecting internal components.
The solenoid contacts are made of copper‑tungsten alloy, which resists welding from high current surges. The motor housing is made of cold‑rolled steel with a corrosion‑resistant e‑coat, and the drive mechanism is lubricated with high‑temperature grease that remains effective from -40°C to +150°C. Unlike cheap aftermarket starters, the LG1611330001 uses genuine OEM‑spec bearings and brushes that provide a service life of over 200,000 starts.
Fleet operators using the LG1611330001 report a 80% reduction in cranking failures and a 50% longer starter life compared to generic rebuilds. The starter’s sealed design also keeps out dust and road spray, a common problem in construction and mining environments.
4.5 kW output at 12V. Provides reliable starting even in sub‑zero temperatures and for high‑compression diesel engines.
Copper‑tungsten contacts, welded steel housing. Resists pitting and ensures positive engagement every time.
Oil‑tempered roller clutch prevents back‑drive damage. Smoother disengagement and longer starter life.

The LG1611330001 Starter Assembly is assembled on a fully automated line, with each component rigorously tested before integration. The armature is dynamically balanced to reduce vibration at high RPM, and the commutator is diamond‑turned to a mirror finish for long brush life. The brushes are made of high‑copper graphite, with a spring force calibrated to maintain constant contact even after extended wear.
The solenoid uses a double‑winding design: a pull‑in coil and a hold‑in coil. This ensures that the starter pinion engages the flywheel ring gear before motor current flows, preventing gear clashing. The solenoid contacts are silver‑tipped to minimize arcing and extend service life. The starter housing is sealed with O‑rings at all mating surfaces, achieving an IP54 rating against dust and water ingress.
Each starter is 100% end‑of‑line tested for current draw, cranking speed, and torque under load. A sample from each batch undergoes a 100,000‑cycle endurance test in a climate chamber (−40°C to +80°C). Only starters that meet all criteria are shipped.
The LG1611330001 uses four long‑life brushes positioned at 90° intervals around the commutator. The brush holder is made of insulating plastic with brass brush boxes to prevent arcing between brushes. The commutator bars are undercut to a depth of 0.5 mm, ensuring that carbon dust does not cause short circuits.
The brushes are replaceable as a set, and genuine SINOTRUK Homan brush kits are available. In normal service, the brush set lasts about 200,000 cranking cycles, far exceeding the life of typical aftermarket starters.
For severe duty (e.g., frequent starts), the starter can be fitted with an optional heavy‑duty brush spring (available separately) to maintain contact pressure under extreme vibration.
The LG1611330001 is a direct replacement for the original starter on SINOTRUK HOWO and SHACMAN trucks equipped with Weichai WP10/WP12 engines. It bolts directly to the engine block using the original mounting holes and the same hardware. The electrical connections use standard M8 studs and a 2‑pin solenoid connector.
To replace: disconnect the battery, remove the starter wires, unscrew the two mounting bolts, and pull the starter out. Clean the mounting flange, apply a thin layer of anti‑seize to the bolts, and install the new starter, torquing bolts to 45 Nm. Reconnect wires (positive cable to the large stud, solenoid trigger to the spade terminal).
After installation, test the starter by cranking the engine for a few seconds before starting to verify correct engagement and speed.
To safely replace a starter with the LG1611330001, follow these steps: 1) Disconnect the negative battery cable and then the positive cable.
2) Raise the vehicle and locate the starter on the engine bellhousing. Remove the electrical connections (large battery cable and solenoid trigger wire).
3) Support the starter with one hand, then remove the two mounting bolts (usually M12 or M14). Lower the starter out of the vehicle.
4) Clean the starter mounting flange and inspect the flywheel ring gear for damage. Apply a thin coat of anti‑seize to the starter nose cone to prevent seizing.
5) Position the new starter and hand‑start the bolts. Torque to 45 Nm (specifications may vary; consult the service manual).
6) Reconnect the battery cable and solenoid wire. Ensure the connections are tight.
7) Reconnect the battery, start the engine and listen for abnormal noise. Verify that the starter disengages promptly after the engine fires.
The LG1611330001 requires periodic inspection of electrical connections and the starter mounting. Every 100,000 km, check the battery cables for corrosion and the solenoid trigger wire for fraying.
Symptoms of a failing starter: slow cranking, a clicking sound without cranking (solenoid engaging but motor not turning), or a grinding noise (pinion not fully engaging). If these occur, first check battery voltage and connections; if they are good, replace the starter.
Never operate the starter for more than 30 seconds continuously. If the engine does not start after 15 seconds of cranking, wait 2 minutes to allow the starter to cool.
Each LG1611330001 Starter Assembly is tested to meet SAE J541 and OEM standards. Tests include: (1) No‑load performance (RPM, current), (2) Locked rotor torque test, (3) Solenoid engagement test (pull‑in/hold‑in), (4) Endurance test (100,000 cranking cycles), (5) Thermal cycle (−40°C to +120°C, 200 cycles), (6) Vibration test (random 10‑500 Hz, 24 hours), (7) Salt spray (240 hours, ASTM B117).
(8) Overload protection verification, (9) EMC test (CISPR 25 Class 3). The starter carries the ECE R10 mark for electromagnetic compatibility. A certificate of conformance is included with each shipment.
The manufacturing facility is IATF 16949 and ISO 14001 certified, with 100% final inspection.
A North American fleet operating 120 HOWO trucks replaced aging starters with the LG1611330001. After 24 months, they recorded a 75% reduction in “no‑start” incidents and a 60% decrease in starter warranty claims. The starters performed flawlessly during a harsh winter with temperatures dropping to -35°C.
A South African mining company using SHACMAN dump trucks in dusty conditions reported that the sealed starter housing kept out dust, while the heavy‑duty solenoid resisted corrosion. Starter life extended from 9 months to over 24 months.
Each LG1611330001 Starter Assembly is packed in a heavy‑duty corrugated box with foam inserts to protect the nose cone and solenoid. The box includes the mounting bolts and a quick installation guide.
A tamper‑evident hologram sticker with the SINOTRUK Homan logo and a QR code is affixed to the starter body. The QR code links to the official authenticity verification portal. Counterfeit starters often have undersized windings, poor commutator finish, or weaker solenoids. Genuine units have a smooth powder‑coat finish, a laser‑etched part number, and a production date code.
Purchase only from authorized distributors. The genuine LG1611330001 comes with a 24‑month / unlimited mileage warranty.
