CNHTC (Sinotruk) Truck Parts Dammam
Sinotruk trucks, built by China National Heavy Duty Truck Group (CNHTC), have become a familiar sight in Dammam's construction and haulage fleets, valued for their load capacity and straightforward maintenance. OZwheel Trading Services sources and supplies parts compatible with Sinotruk trucks for workshops and fleets across the Eastern Province, covering HOWO, Sitrak and Steyr models.
Sinotruk's WD615 series and later MC-series engines power most of the tippers, mixers and tractor units working Dammam's project sites and port routes, and the parts needed can vary between build generations even within the same model name. We work from the chassis number and, where the job calls for it, the engine serial number, so the part we quote matches the specific truck in front of you.
This page sets out the categories of Sinotruk parts we supply, what tends to fail on HOWO, Sitrak and Steyr trucks, and how Gulf heat and dust affect that wear. If you already know what you need, send a part number or a photo on WhatsApp for a quote.
Sinotruk part categories we supply
We source and supply parts compatible with Sinotruk trucks across the systems that see the most wear in construction, tipper and haulage duty.
- Engine: parts for the WD615 series and later MC-series engines, including pistons, liners, bearings, oil pumps and gasket sets for overhaul work.
- Brake: air-brake valves, chambers, linings, drums and components for HOWO and Sitrak braking systems.
- Suspension: leaf springs, shock absorbers and bushes built for the heavier loads common on tipper and mixer chassis.
- Electrical: sensors, relays, wiring sections and connectors for the truck's engine management and lighting systems.
- Filtration: air, oil and fuel filters sized to WD615 and MC-series engines, which see heavy demand on dusty sites.
- Cooling: radiators, water pumps and fan clutches for engines working continuously under load in high heat.
- Steering: power steering pumps, steering boxes and linkage for HOWO and Steyr front axles.
- Transmission and driveline: clutch kits, gearbox components, driveshafts and heavy-duty axle parts for tipper and mixer applications.
- Turbochargers and fuel system: turbo units and injection components matched to WD615 and MC-series engine codes.
Sinotruk HOWO, Sitrak and Steyr: what tends to wear
Each Sinotruk range covers a slightly different segment of the market in Dammam, and the parts ordered most often reflect the jobs these trucks do.
Sinotruk HOWO
The HOWO range is the most common Sinotruk model in the Eastern Province, used heavily as tippers, mixers and tractor units on construction and port-adjacent work. Suspension components, clutch kits and axle seals are frequent orders, reflecting the load and rough-surface duty these trucks are put through.
Sinotruk Sitrak
Sitrak is CNHTC's more recent, higher-specification range, increasingly used for long-haul and regional tractor work. Cooling system and turbocharger parts see steady demand on Sitrak tractors running sustained highway loads, alongside the same suspension and brake wear seen across the range.
Sinotruk Steyr
The Steyr-badged range, built on an older CNHTC platform, remains in service across a number of Dammam fleets and tends to need more engine and driveline parts as trucks accumulate higher mileage. Bearings, gaskets and clutch components are the parts most often requested for Steyr trucks still in daily use.
How Eastern Province heat and dust affect Sinotruk parts
Summer air temperatures above 45 degrees Celsius leave a Sinotruk diesel little cooling margin, and a cooling system already working hard on a loaded tipper or mixer will show weakness first as an overheating warning or a head gasket failure. Dust is a particular concern for HOWO and Steyr trucks working construction sites, where a cracked or loose intake joint downstream of the air filter lets fine sand into the cylinders, producing the same bright liner scoring and gritty oil seen across every heavy-duty brand. Fleets running Sinotruk tippers on project sites should inspect intake seals at every service, not only when the filter element is due.
Long idling at loading points and factory gates is common for Sinotruk trucks working construction and distribution routes, which glazes cylinder walls and dilutes engine oil with unburnt fuel over time. Coastal humidity adds condensation and slow corrosion to connectors and relays on the truck's electrical system, so an intermittent warning light or an erratic sensor reading is often a corrosion issue rather than a component defect. Suspension bushes and leaf spring mounts on HOWO tippers running rough site tracks in sustained heat also wear faster than the same parts would on paved routes, so a shorter suspension inspection interval is worth building into the service schedule.
What to send us when you order Sinotruk parts
These details help us confirm fitment quickly, since HOWO, Sitrak and Steyr trucks of the same name can carry different engine generations and axle configurations depending on the build year.
- Read the chassis (VIN) number from the plate on the cab and note the model, engine and year.
- For engine parts, find the WD615 or MC-series engine serial number stamped on the block if you can.
- Photograph the old or failed part from two angles, including any stamped or moulded part number.
- Tell us whether the truck is a HOWO, Sitrak or Steyr and how it is used, since suspension and axle parts differ across construction, tipper and haulage applications.
- Send everything on WhatsApp to +966 53 870 9021, and we will confirm what we can source before you commit.
Sinotruk truck parts questions from Dammam fleets
Are you an authorized Sinotruk or CNHTC distributor?
No. OZwheel is an independent parts supplier. We source and supply parts compatible with Sinotruk trucks, and we are upfront about that. Send us the chassis number and the part you need, and we will confirm what is available.
Can you supply parts for older Steyr-badged trucks?
In many cases yes. Send the chassis number and, where possible, the number on the old part, and we will check what is available for that specific build. Older Steyr trucks sometimes need a part cross-referenced from the original number, which we can usually do from a clear photograph.
Do HOWO tippers need heavier suspension parts than other Sinotruk models?
Often yes. HOWO tippers and mixers carry heavier loads on rougher surfaces than a Sitrak tractor running highway routes, and typically need heavier-duty leaf springs, bushes and shock absorbers. Tell us how the truck is used and we will match the part to that duty.
Are Sinotruk engine parts hard to source in Dammam?
Not usually, given the WD615 and MC-series engines are common across the Eastern Province fleet. The main risk is ordering against the wrong engine generation, which is why we ask for the engine serial number before confirming a quote for pistons, liners or bearings.
Can I collect Sinotruk parts from your Dammam location?
Yes. Message us on WhatsApp first to confirm the part is available and ready, then collect from our As Sinaiyah address in Dammam.
