HOWO 336 Trucks for Sale — Inspected, Refurbished, CIF Worldwide

What Is the HOWO 336?

HOWO is the heavy-duty truck brand of Sinotruk (China National Heavy Duty Truck Group). Within the HOWO range, engine output is the key differentiator between variants — and the HOWO 336 refers specifically to trucks fitted with the WD615.69 engine producing 336 HP.

The WD615 family is a six-cylinder in-line turbocharged diesel engine developed with technology licenced from Steyr of Austria. It has been in production for decades, which means parts are standardised, widely available, and understood by mechanics from Johannesburg to Lagos to Baghdad. The 336HP tune is the lower output setting of this engine platform, below the 371HP variant that dominates long-haul and high-payload applications.

Most HOWO 336 trucks are configured as 6×4 dump trucks (tippers), though tractor-trailer units exist. The 6×4 drivetrain gives good traction on unpaved and dirt roads — a practical advantage for construction sites, quarries, and rural infrastructure projects across sub-Saharan Africa and the Middle East.

In short: if you have seen a howo truck on a construction project in East Africa or in an Iraqi road-building scheme, there is a strong chance it was running on a 336HP or 371HP WD615 engine.

HOWO 336 vs HOWO 371 — Which One Do You Need?

The most common question buyers ask is whether to choose the HOWO 336 or the howo 371. Here is a plain comparison:

• HOWO 336HP: Lower output, lower fuel burn per cycle, lower purchase price. Best for moderate payloads (typically up to around 20–25 tonnes depending on body and axle rating), flat to gently rolling terrain, urban or peri-urban construction logistics, and buyers running large fleets where unit cost and fuel economy matter more than maximum productivity per truck.
• HOWO 371HP: Higher output, suited to heavier payloads, steeper gradients, longer hauls, and mining or quarry applications where trucks are loaded to the legal maximum every cycle.

If your routes are flat, your loads are moderate, and you are buying five or ten trucks at once, the 336 will likely give you a better total cost of ownership. If you are running a single truck on a hard mining haul with full loads every trip, the 371 is the safer choice. Neither is universally better. The right answer depends on your routes, your loads, and your operating cost model.

Engine, Gearbox, and Parts Availability

The WD615.69 336HP engine is one of the most widely distributed heavy-truck engines in the developing world. This is commercially significant for buyers:

• Parts are available locally in most of Sigma's target markets. Nairobi, Lagos, Kampala, Dar es Salaam, Dubai, and Basra all have established HOWO parts networks. You are not dependent on air-freighting components from China for routine maintenance items.
• Local mechanics know this engine. The WD615 has been in the field long enough that diesel workshops across Africa and the Middle East have technicians familiar with it. This reduces downtime and service costs.
• Sinotruk operates authorised service centres in several African countries. For major overhaul work, this network provides additional support.

The HW series 10-speed manual gearbox paired to the 336HP engine is robust and well-matched to the engine's torque curve. Synchronised gear changes reduce driver error, and the gearbox is likewise well-supported in the parts aftermarket. Tyres are 12R22.5, a size available from multiple manufacturers in Africa and the Middle East. You are not locked into a proprietary or exotic tyre size.

Available Configurations — Dump Trucks, Tippers, and Tractors

Sigma sources HOWO 336 units in the configurations most requested by buyers:

• 6×4 Dump Truck / Tipper: The dominant configuration. Used in construction, road building, quarrying, and aggregate haulage. A howo dump truck in this output class is well-suited to municipal contracts and mid-scale earthmoving where the 371HP would be overcapacity. See also our broader range of dump trucks and 6x4 dump truck stock.
• 6×4 Tractor Unit: Paired with a semi-trailer for general freight, agricultural produce, or containerised cargo. The 336HP tractor is economical for shorter trunk routes where the trailer is not loaded to maximum capacity.
• 4×2 Variants: Less common, but available on request. Suited to lighter applications and better-surfaced roads.

Body condition, dump body capacity, hydraulic system, and fifth-wheel specs (for tractors) vary by unit. Sigma provides unit-specific photos and inspection reports at inquiry stage so buyers can assess condition before committing.

Refurbishment, Inspection, and Export Process

Every HOWO 336 unit leaving Sigma goes through an in-house inspection and refurbishment process before export. This is not a paper-based check — it covers mechanical, structural, and electrical condition.

Key steps in the process:

• Engine and transmission inspection: Oil condition, compression, turbocharger function, gearbox engagement, and leak checks.
• Chassis and body inspection: Frame integrity, dump body condition, hydraulic cylinder and pump function, tyre tread depth, and brake system.
• Electrical systems: Lights, instruments, and cab electrics checked and repaired as needed.
• LHD/RHD conversion: Carried out in-house for markets that require right-hand drive. Countries including South Africa, Kenya, Uganda, Tanzania, and Zambia drive on the left and import RHD trucks. Sigma's in-house conversion avoids the quality risk of outsourcing this to third parties.

After inspection, Sigma handles export documentation, container loading or Ro-Ro booking, and CIF shipment to the buyer's destination port. For buyers new to importing Chinese trucks, Sigma's team can advise on typical import duty classifications and required documentation for their country — though buyers are responsible for confirming local import regulations with their own clearing agents.

Buyers looking at trucks for sale in south africa should note that South Africa requires RHD and has specific roadworthiness standards — Sigma accounts for both in the pre-export process.

Buyer Checklist — What to Confirm Before You Order

For buyers considering a used HOWO 336, here are the key points to verify before placing an order:

• Engine hours or mileage: Ask for the odometer reading and, where available, engine hours. Lower mileage units command higher prices but lower refurbishment risk.
• Year of manufacture: Affects emission compliance in certain destination markets. Confirm with your local import authority what year restrictions apply.
• Emission standard: The WD615.69 is available in Euro II and Euro III tunes. Some markets have minimum emission requirements for imported trucks.
• Body specification: For dump trucks — confirm dump body volume (cubic metres), hydraulic system condition, and tailgate operation. For tractors — confirm fifth-wheel type and coupling height.
• Drive side: Confirm whether you need LHD or RHD for your market. Do not assume — specify explicitly in your enquiry.
• Destination port: CIF pricing is calculated to a named port. Confirm your preferred discharge port (e.g. Durban, Mombasa, Lagos Apapa, Dar es Salaam, Jebel Ali, Umm Qasr) when requesting a quote.
• Quantity: Multi-unit orders may be eligible for fleet pricing. Specify your required quantity upfront.
