How to properly store SPARE PARTS for Sinotruk trucks in winter? 

Why proper storage of HOWO spare parts in winter is a matter of fleet survival

Low temperatures, high humidity and pressure changes in winter turn an ordinary warehouse into a testing ground for strength. IfSPARE PARTS for HOWOare stored incorrectly, the risk of equipment failure increases by 40–60% already in the first weeks of operation after downtime. In our practice, there was a case when a client from Novosibirsk lost two trucks due to cracked cooling system pipes: the parts were stored in an unheated hangar at a temperature of -25°C without special packaging. The rubber simply “stiffened” and burst when the engine was first started. This article will give you a clear algorithm of actions based on real experience of working with Chinese trucks in harsh climatic zones.

Critical vulnerabilities of rubber products and polymers at sub-zero temperatures

Industrial rubber products (RTI) are the most vulnerable category of components during winter storage. Pipes, oil seals, O-rings and silent blocks lose elasticity faster than metal parts are subject to corrosion. At temperatures below -15°C, the molecular structure of many types of technical rubber changes irreversibly if the part has not been prepared in advance.

We observed a situation where a batch of new air filters and boots for SITRAK and HOWO trucks sat on the open concrete floor of a warehouse for three months. The result was disastrous: 30% of the anthers developed microcracks during installation that were impossible to notice visually. After a month of operation, dust entered the turbine, which led to costly repairs to the Weichai engine. The problem was not the quality of the product, but a violation of the storage temperature conditions.

To preserve the properties of rubber goods, it is necessary to follow strict rules:

• Temperature:The optimal storage temperature for rubber parts is from +5°C to +25°C. A short-term drop to 0°C is allowed, but not lower. Storage at sub-zero temperatures is strictly prohibited for pre-tensioned seals.
• Light protection:Ultraviolet radiation destroys bonds in polymer chains even in winter. Parts should be in opaque packaging or in dark areas of the warehouse.
• No mechanical stress:The pipes must not be stored bent or under the weight of other loads. The deformation in the frozen state is fixed forever.

CompanyJinan Mattlid Auto Co.,Ltd, based in Jinan, the hub of China's automotive industry, places special emphasis on the pre-sale preparation of such sensitive components. We use multilayer packaging with desiccant, which allows us to preserve the properties of rubber even during long-term sea transportation through cold regions. When receiving the shipment, be sure to check the production date markings: rubber older than 3 years requires mandatory laboratory testing before installation, regardless of storage conditions.

Metal components: combating condensation and pitting

It would seem that the metal should be resistant to cold. However, the main threat to brake discs, hubs, suspension components and engine parts is not frost, but condensation. When the temperature in a warehouse fluctuates (for example, +2°C during the day, -10°C at night), moisture forms on the surface of metal parts. In combination with salt, which may remain on parts after factory testing or transportation, this starts the process of active corrosion.

The situation is especially critical for the brake systems of SHACMAN and FAW trucks. Rust on the working surface of the brake disc or drum reduces braking efficiency and causes the steering wheel to wobble. In one case, our partner was faced with the fact that a new batch of brake pads arrived with oxidized metal base plates. The reason turned out to be a violation of the tightness of the shrink film during customs clearance.

To protect metalSPARE PARTS for HOWOand other brands, follow these instructions:

1. Humidity control:The relative humidity in the warehouse should not exceed 60%. Use industrial dehumidifiers. If the warehouse is unheated, ensure constant air circulation to avoid stagnant areas with high humidity.
2. Conservation:Parts supplied without factory preservative lubricant (for example, some transmission elements) require additional treatment with anti-corrosion compounds before long-term storage.
3. Floor insulation:Never place pallets of metal directly on a concrete floor. Concrete attracts moisture and cold. Use wooden pallets that are at least 15 cm high.

It is important to note the standardGOST 9.014-78, which regulates temporary anti-corrosion protection of products. Although many Chinese manufacturers rely on domestic GB/T standards, when importing into Russia and the CIS countries, we recommend requiring the supplier to comply with requirements similar to GOST, especially for parts intended for northern regions. Specialists from Jinan Mattlid Auto LLC carry out the final verification of the packaging of each batch, taking into account the climatic characteristics of the delivery region, be it the Southern Urals or Central Siberia.

Electrical and Electronics: Hidden Dangers of Winter Storage

Modern HOWO and SITRAK trucks are full of electronics. ABS sensors, engine control units (ECUs), headlights and wiring harnesses are extremely sensitive to temperature changes and static electricity. The main mistake when storing electronics is ignoring the dew point.

If you take a cold electronic part from outside (-20°C) into a warm office (+22°C) and immediately unpack it, condensation will immediately form inside the units. Turning on such a part will result in a short circuit. We have recorded cases of failure of expensive control units due to violation of this simple acclimatization rule.

Rules for safe storage of electrical equipment:

• Temperature stability:Electronics should only be stored in heated areas with minimal daily temperature fluctuations.
• Antistatic protection:All components must be in antistatic bags. Ordinary polyethylene accumulates a charge that can penetrate microcircuits.
• Batteries:If you store batteries, they must be charged at least 70% and stored in a room with a temperature of at least +5°C. A discharged battery freezes in the cold, the electrolyte expands and destroys the housing.

When ordering electronics from suppliers like Jinan Mattlid Auto LLC, pay attention to the presence of original factory packaging with holograms and security seals. The company works directly with authorized manufacturers, which eliminates the risk of receiving counterfeit products, which often do not have adequate protection from moisture and static. Our team of technical engineers with over 15 years of experience conduct random integrity checks of contacts and connectors before shipment, minimizing risks to the customer.

Organization of warehouse space: zoning and logistics

Chaotic storage of spare parts is a direct path to losses. In winter, the cost of error increases, since access to some areas of the warehouse may be limited by snow or ice, and finding the right part in cold weather takes longer, increasing equipment downtime.

Recommended warehouse zoning scheme for the winter period:

Pay attention to the FIFO (First In, First Out) principle of inventory rotation. In winter, old stock that has been sitting over the summer may have hidden defects from heat and humidity. They require careful inspection before being put into operation. The logistics infrastructure of Jinan Mattlid Auto LLC is built in such a way as to ensure the safety of cargo at all stages. We don’t just ship the goods, but accompany them with documentation, providing comprehensive technical data and storage recommendations for each specific type of part.

Frequently Asked Questions

Is it possible to store HOWO parts outside under a tarp?

Strongly not recommended for most components. Under the tarpaulin, a greenhouse effect is created: during the day the sun heats the air, at night it cools, causing abundant condensation. This kills electronics and causes metal corrosion. The only exceptions are fully painted body parts or tires, but it is better to keep them on pallets in a closed shed.

How long can motor oil and technical fluids be stored in winter?

If the temperature conditions are observed (+5...+25°C), the shelf life of oils is up to 5 years from the date of production. However, if the oil is frozen (the pour point is exceeded), its structure is disrupted. After defrosting, such oil cannot be used - it has lost its lubricating properties. Always check the filling date on the canister.

What to do if spare parts have already been damaged by frost?

If the rubber has become hard as stone or is covered with a network of small cracks, the part must be disposed of. It is impossible to restore the properties of vulcanized rubber. Metal parts with surface rust can be cleaned and preserved, but if corrosion has affected the seats or threads, replacement is required. Don't risk driver safety to save on parts.

Final recommendations and quality control

Winter dictates its own conditions, and neglecting the rules for storing spare parts costs fleets more than the cost of the parts themselves. Remember: proper packaging, humidity and temperature control is not bureaucracy, but a way to maintain the liquidity of your assets. We have seen how proper storage saved consignments of goods even during extreme interruptions in warehouse heating.
