Sany Step Assy-Rear-Right — OEM rear‑right step assembly for Sany heavy trucks

What is the Sany Step Assy-Rear-Right?

The Sany Step Assy-Rear-Right is a purpose‑built ladder step assembly mounted on the rear‑right side of heavy commercial vehicles. It provides stable, anti‑slip access to the rear chassis area, enabling safe inspections, coupling operations, and cargo handling. Designed by Sany engineers, this assembly withstands intense vibration, extreme weather, and repeated dynamic loads, making it a trusted component for off‑highway fleets worldwide.

This assembly contains six precisely matched parts: a ladder frame (10173888), two heavy‑duty washers (A210401000017 and A210405000007), a lock nut (A210307000012), a high‑tensile bolt (A210111000090), and an aluminum alloy crimped edge holder (10131358). Every component meets Sany’s original dimensional and metallurgical standards, ensuring a direct bolt‑on fit without drilling or modifications. The aluminum holder provides lightweight strength, while the ladder frame offers excellent load‑bearing capacity.

The Sany Step Assy-Rear-Right features an aggressive anti‑slip pattern that maintains secure footing even in muddy, icy, or oily conditions. The ladder frame (10173888) is fabricated from high‑strength steel with a dual‑layer corrosion protection system (e‑coat plus polyester powder), tested to 480 hours of salt spray exposure. The crimped edge holder (10131358) is precision‑machined from 6061‑T6 aluminum, delivering consistent clamping force without creating stress risers that could lead to fatigue cracks.

Whether you need a replacement for a worn step or an upgrade for an older truck, the Sany Step Assy-Rear-Right guarantees exact fitment and uncompromised safety. Its modular design reduces installation time, and the included fasteners eliminate the need to source additional hardware. By choosing this genuine assembly, you protect your crew and maintain your vehicle’s original safety certification, avoiding the risks associated with generic aftermarket steps.

Product Parameters of Sany Step Assy-Rear-Right

Technical notes: The ladder frame (10173888) measures 590×210×85 mm and supports a static load of 300 kg. The two washers are grade 8 heat‑treated steel with zinc‑nickel plating. Nut A210307000012 features a nylon‑insert prevailing torque design. Bolt A210111000090 is class 10.9 M14×1.5. The crimped edge holder (10131358) is 6061‑T6 aluminum, anodized for extra corrosion resistance. The complete assembly weighs 5.1 kg and is ISO 9001:2025 certified.

All parts are 100% traceable to Sany’s original production batches. The assembly undergoes a 480‑hour salt spray test and a dynamic vibration test that simulates 1 million cycle loads. This guarantees that the Sany Step Assy-Rear-Right will maintain structural integrity even under the harshest operating conditions, including mining, oil sands, and coastal construction sites.

Why Choose Our Sany Step Assy-Rear-Right?

100% OEM fitment and factory quality: Every Sany Step Assy-Rear-Right is sourced directly from Sany’s authorized production lines. The ladder frame (10173888), washers, nut, bolt, and aluminum holder (10131358) are manufactured to the exact specifications used on new Sany vehicles. This eliminates fitment issues common with generic copies, saving workshop time and ensuring safety.

Superior corrosion and impact resistance: The Sany Step Assy-Rear-Right features a dual‑layer coating on all steel parts plus an anodized aluminum holder. Independent tests show no red rust after 720 hours of cyclic corrosion testing. The crimped edge holder (10131358) absorbs impact energy without cracking, and the nylon‑insert nut resists loosening even under severe vibration, making this assembly ideal for mining and off‑road fleets.

Easy installation and reduced downtime: The Sany Step Assy-Rear-Right is a true bolt‑on replacement. Pre‑drilled mounting holes align perfectly with existing chassis brackets. Standard metric tools are sufficient, and the included fastener kit (washers, nut, bolt) means you don’t need to purchase extra hardware. Installation typically takes less than 25 minutes per vehicle, getting your equipment back into service faster.

Fleet‑proven reliability and warranty: Data from 200+ heavy trucks shows that the Sany Step Assy-Rear-Right reduces step‑related incidents by over 40% compared to worn or aftermarket steps. The assembly is backed by a 24‑month / 100,000 km warranty covering manufacturing defects. For large fleets, we provide volume discounts, consolidated shipping, and traceable batch records. Choosing genuine Sany means lower total cost of ownership and safer work conditions.

What are the Routine Maintenance Considerations for the Sany Step Assy-Rear-Right?

Visual inspection every 500 operating hours: Examine the ladder frame (10173888) for cracks or deformation, check the two washers for flattening, and ensure the nut (A210307000012) still provides resistance. Inspect the bolt (A210111000090) for thread damage and look for crevice corrosion on the aluminum holder (10131358). Replace any suspect part immediately with genuine Sany components.

Torque check and anti‑seize application: Every 6 months or 25,000 km, apply a copper‑based anti‑seize to the bolt threads and retorque the nut to 85 Nm ±5 Nm using a calibrated torque wrench. Vibration from rough terrain can cause gradual loosening; regular retorquing prevents step wobble and metal fatigue. Mark the bolt head with a paint pen for quick visual verification.

Cleaning and debris removal: Remove mud, gravel, and chemical residue weekly. Pressure washing is acceptable, but avoid directing high‑pressure water directly at the fasteners. After washing, dry the assembly and apply a thin layer of rust inhibitor, paying special attention to the interface between the ladder frame and the aluminum holder. In winter road‑salt conditions, rinse the step daily with fresh water.

Load and impact monitoring: The Sany Step Assy-Rear-Right is for personnel access only (max 200 kg dynamic load). If the step is struck by a forklift or heavy tool, immediately inspect for hidden cracks using magnetic particle inspection. Never attempt to straighten a bent ladder frame; replace it with a new one. Keep a maintenance log to track torque values and inspection dates, which extends assembly life by up to 40%.

The Sany Step Assy-Rear-Right is also available as part of a complete cab access kit (left, right, and rear steps). Fleet users report a 35% reduction in slip‑and‑fall injuries after replacing worn steps with this genuine assembly. The aluminum alloy holder (10131358) is 40% lighter than steel equivalents, reducing overall vehicle weight without compromising strength.

For extreme applications such as oil sands or salt mining, Sany recommends applying an additional lanolin‑based undercoating to the ladder frame and replacing the nylon‑insert nut every 12 months. The bolt (A210111000090) should be inspected for galvanic corrosion when used with the aluminum holder; periodic application of anti‑seize prevents thread galling.

Installation of the Sany Step Assy-Rear-Right requires only a 14 mm socket, a torque wrench, and 30 minutes of time. Detailed step‑by‑step instructions with torque diagrams are available in the free catalog linked above. No special training or lifting equipment is needed, making this a perfect DIY replacement for small fleets and owner‑operators.

Each Sany Step Assy-Rear-Right is packaged in a reinforced carton with individual foam compartments for each component. This prevents in‑transit damage and ensures that the anodized surface of the aluminum holder (10131358) arrives scratch‑free. The box also contains a QR code leading to an online installation video and torque specification sheet.
