Product Introduction

Structure

This steering oil tank filter is a precision-engineered cylindrical filtration element, featuring a multi-layer composite structure. The outer layer is a perforated metal mesh (steel or stainless steel) with uniform circular holes, providing mechanical support and coarse filtration. Inside, it consists of high-density filter paper or fiberglass media, sandwiched between top and bottom rigid end caps (metal or high-strength plastic) for structural integrity and sealing. The entire assembly is designed for direct replacement within the steering oil tank housing, ensuring a precise fit and optimal filtration performance.

Performance

The multi-layer filtration media delivers high filtration efficiency (≥98% for particles ≥10μm), effectively removing contaminants, sludge, and particulate matter from the hydraulic steering fluid. The perforated outer mesh provides excellent durability and resistance to pressure fluctuations, while the end caps ensure a secure, leak-proof seal. The filter maintains consistent performance in temperatures ranging from -40°C to 120°C, resisting chemical degradation from hydraulic fluids and ensuring long service life under heavy-duty operating conditions.

Core Function

1. Removes contaminants and particulate matter from the hydraulic steering fluid, protecting precision components such as the steering gear valve core, pump, and seals from premature wear and blockage.

2. Maintains the cleanliness of the hydraulic fluid, extending the service life of the fluid and the entire steering system.

3. Prevents fluid contamination-related failures, such as stiff steering, noise, or system leaks, ensuring reliable and responsive steering operation.

Key Functions and Benefits of the Steering Oil Tank Filter 712W47301-0133+001

So, what exactly does this steering oil tank filter do for your Sitrak truck? Let’s break it down clearly:

Precision Contaminant Removal

Over time, steering hydraulic oil accumulates microscopic metal shavings, rubber seal debris, and oxidation byproducts. The 712W47301-0133+001 filter element is specifically designed to trap these contaminants before they reach sensitive steering pump components and control valves. As a result, your steering system stays responsive and free from premature wear.

Extended Steering System Lifespan

Clean hydraulic fluid means less abrasive damage to internal seals, rotors, and valve surfaces. By consistently filtering out harmful particles, this steering oil tank filter helps you avoid costly steering pump replacements and reduces unplanned downtime — something every fleet manager appreciates.

Stable Steering Performance Under Load

Sitrak trucks often operate under heavy payloads and demanding road conditions. A clogged or degraded filter restricts fluid flow, leading to stiff steering, increased driver fatigue, and potential safety hazards. Replacing with a fresh 712W47301-0133+001 filter restores optimal flow rates and keeps steering effort consistent, even during long-haul operations.

OEM-Matched Filtration Specifications

This filter is manufactured to match the original equipment specifications for Sinotruk Sitrak vehicles. The filtration media grade, housing dimensions, and sealing interfaces are all engineered to fit perfectly without modification — giving you a drop-in replacement that performs exactly as the factory intended.

Cost-Effective Preventive Maintenance

Compared to the expense of repairing a damaged steering pump or replacing corroded hydraulic lines, a routine filter change is remarkably affordable. Think of it as inexpensive insurance for one of your truck’s most safety-critical systems.

Technical Specifications — Steering Oil Tank Filter 712W47301-0133+001

Application Scenario — Where Does This Filter Belong?

The Steering Oil Tank Filter 712W47301-0133+001 is specifically designed for Sinotruk Sitrak series heavy-duty trucks. It installs directly inside the power steering oil reservoir (oil tank), where it serves as the first line of defense against fluid contamination.

In real-world operation, every time the driver turns the steering wheel, hydraulic fluid circulates through the pump, control valve, and steering cylinder before returning to the reservoir. During this cycle, tiny particles inevitably enter the fluid — from normal component wear, seal degradation, or external contamination during maintenance. The 712W47301-0133+001 filter catches these impurities right at the reservoir, preventing them from recirculating and causing progressive damage.

This filter is particularly essential for Sitrak trucks operating in:

• Long-haul logistics — where consistent steering feel reduces driver fatigue over thousands of kilometers
• Construction and mining transport — where dust-heavy environments accelerate fluid contamination
• Urban delivery fleets — where frequent steering inputs increase system wear rates

Frequently Asked Questions — Steering Oil Tank Filter 712W47301-0133+001

What symptoms indicate that the steering oil tank filter needs replacement?

Common signs include noticeably heavier steering effort, unusual whining or groaning noises from the power steering pump, and visible discoloration or particulate matter in the steering fluid. If you notice any of these, the filter is likely saturated and restricting fluid flow — replacement should be prioritized promptly.

How often should the 712W47301-0133+001 steering filter be replaced?

While replacement intervals depend on operating conditions, most fleet operators replace the steering oil tank filter every 40,000–60,000 km or during scheduled steering fluid changes. Trucks operating in dusty or extreme environments may benefit from shorter intervals to maintain optimal filtration.

Is this filter a direct fit for all Sitrak truck models?

The 712W47301-0133+001 is designed as a direct OEM replacement for Sinotruk Sitrak trucks equipped with the corresponding steering oil reservoir assembly. It requires no modifications and installs in the same position as the original factory filter. However, we recommend confirming your specific vehicle’s part number before ordering to ensure exact compatibility.

Can a clogged steering filter damage the power steering pump?

Absolutely. When the filter becomes blocked, it starves the steering pump of clean fluid, causing cavitation, overheating, and accelerated internal wear. In severe cases, this leads to complete pump failure — a repair that costs significantly more than a simple filter replacement. Regular filter changes are one of the most cost-effective ways to protect your steering system.

What is the difference between this filter and an aftermarket alternative?

The 712W47301-0133+001 from Mettlead is manufactured to OEM dimensional and filtration specifications, using quality-controlled media that matches the original equipment’s particle capture efficiency. Many generic aftermarket filters use lower-grade media or imprecise dimensions, which can result in bypass leakage or insufficient contaminant removal. With our product, you get factory-spec performance at a competitive price.

Does Mettlead offer other steering system components for Sitrak trucks?

Yes. Beyond the steering oil tank filter, we supply a comprehensive range of Sitrak steering system parts including power steering pumps, steering gearboxes, hydraulic hoses, and reservoir assemblies. You can explore the full selection in our Chassis System Parts section.
