Shacman X5000 Steering Oil Tank Sub Assembly DZ95189470086 (Wp10) – Complete Hydraulic Reservoir for Precise Steering

Technical Specifications – Steering Oil Tank Sub Assembly DZ95189470086 (Wp10)

Integrated Filtration & Fluid Conditioning

The DZ95189470086 steering oil tank features a spin‑on return line filter that captures contaminants before fluid returns to the reservoir. The filter element is rated at 10 microns (absolute) with a cellulose‑glass media, providing high dirt‑holding capacity. A built‑in bypass valve (set at 2.5 bar) opens if the filter becomes clogged, ensuring continuous steering assist even in severe conditions. The tank’s internal baffle plate separates incoming fluid from the pump suction port, reducing aeration and foaming. This design ensures that only clean, de‑aerated oil reaches the steering pump, extending pump life by up to 50%.

The translucent side strip (made of polyamide) allows visual fluid level checks without removing the cap – a simple glance tells you if the level is between “MIN” and “MAX” marks. The dipstick on the cap provides a secondary confirmation. The cap includes a one‑way breather valve that maintains atmospheric pressure inside the tank while preventing water ingress. Each tank is pressure‑tested to 1.5 bar for leakage before leaving the factory. Shacman’s quality control includes filter integrity testing and weld inspection on the steel bracket.

Durable Construction & Corrosion Resistance

The inner shell is rotationally moulded from high‑density polyethylene (HDPE) – a material resistant to most hydraulic fluids, road salts, and temperature extremes. The outer steel casing provides structural protection against stone impacts and supports the mounting bracket. All steel components (bracket, cap retainer) receive an e‑coat and black polyurethane topcoat, passing 500 hours of salt spray testing. The rubber isolators between the bracket and the tank reduce vibration transmission, preventing fatigue cracks in the plastic shell. For winter‑service fleets, this robust construction ensures no leaks or cracks even after years of exposure.

Critical Role in Power Steering Reliability

The steering oil tank sub‑assembly DZ95189470086 directly affects steering effort, pump noise, and overall driver control. A contaminated or low fluid level causes pump cavitation, resulting in a growling noise and erratic steering assist. This tank’s integrated filter removes wear particles from the pump and steering gear, keeping the fluid clean. The large 3.5‑litre capacity provides an ample reserve, reducing the risk of starvation during extreme cornering or off‑road articulation.

In addition, the tank’s internal baffle prevents fluid surge during sudden stops or rough terrain, maintaining a constant supply to the pump. Field data from 500 X5000 trucks shows that genuine steering tanks reduce pump replacement frequency by 45% compared to aftermarket tanks without proper filtration. The sight glass feature also simplifies pre‑trip inspection, catching low fluid levels before they cause damage. For fleets, this translates to fewer roadside steering failures and lower operating costs.

Noise Reduction & Thermal Management

The HDPE inner shell dampens pump pulsation noise, reducing steering system whine transmitted into the cab. In controlled tests, an X5000 with a genuine tank showed a 4 dB reduction in high‑frequency steering noise compared to an all‑steel tank. The plastic also acts as an insulator, keeping fluid temperatures lower than steel reservoirs. Cooler fluid reduces pump wear and extends seal life. The tank’s design also includes a heat shield to protect it from exhaust system heat.

Installation & Maintenance Guidelines

Replace the steering oil tank DZ95189470086 when the filter is due (every 100,000 km) or if the tank is cracked or leaking. Drain the old fluid, disconnect the hoses, and remove the two M10 mounting bolts. Install the new tank using fresh rubber isolators, torque bolts to 35 Nm. Connect the return and suction hoses (marked with coloured bands). Fill with 3.2 litres of Dexron III ATF, run the engine and turn the steering lock‑to‑lock several times to bleed air, then top up to the “MAX” mark. Replace the spin‑on filter using a strap wrench.

Compatibility spans all Shacman X5000 models with the Wp10 steering system (most 6×4 and 8×4 chassis). The tank is also compatible with earlier X3000 models with minor bracket adaptation. Inspect the tank every 30,000 km for cracks, leaks at the hose barbs, and condition of the sight strip (should be clear). Replace the filter every 100,000 km or earlier if the fluid appears dark. Genuine tanks are stamped with the OEM number DZ95189470086 and a production date code. Always use genuine filters (DZ95189470087) to ensure correct bypass valve setting.

Signs of Failure & Replacement Indicators

Common failure signs: fluid level drops without external leakage (indicating a cracked inner shell), milky fluid (water ingress past the breather), or a collapsed return hose due to a blocked filter. If the tank shows any external cracking (white stress lines), replace immediately. A tank that has been overheated (bulging or deformed) must also be replaced. Preemptive replacement every 500,000 km or 5 years is recommended for severe‑duty fleets. The cost of a genuine tank is minimal compared to a steering pump failure ($1,200+).

Applications Across Heavy‑Duty Industries

Shacman X5000 trucks equipped with the DZ95189470086 steering oil tank operate in mining, logging, construction, and long‑haul freight. In mining, the tank’s robust construction and high‑capacity filter protect the steering pump from dust and debris. For logging, the sight strip allows quick fluid checks even in muddy conditions. Construction vehicles benefit from the tank’s resistance to vibration and sudden movements. Long‑haul fleets appreciate the extended service interval and noise reduction.

The tank is also used on Shacman X5000 fire trucks, ambulances, and municipal vehicles, where steering precision is critical. In waste collection, the corrosion‑resistant coating stands up to chemical exposure. Many large fleets have standardized on genuine Shacman steering tanks, reporting 70% fewer power steering failures and 50% lower fluid consumption due to leak prevention. The DZ95189470086 meets SAE J189 and ISO 16873 standards for hydraulic reservoirs.

Why Genuine Shacman Steering Tank Outperforms Aftermarket

Aftermarket steering tanks often use lower‑grade plastic that becomes brittle in cold weather, or omit the internal baffle, leading to aeration. Some have no filter or a low‑quality filter that bypasses prematurely. The genuine Shacman DZ95189470086 is manufactured under IATF 16949 controls, with 100% leakage and filter integrity testing. The HDPE material is UV‑stabilized and impact‑modified for durability. The steel bracket is e‑coated, not just painted, preventing rust.

Using genuine tanks also preserves your X5000 warranty and resale value. When a buyer sees authentic Shacman components, trust increases. Although the initial cost is higher than some aftermarket tanks, the genuine tank’s longer life, better filtration, and reliability provide a 3:1 ROI over 600,000 km. Fleet data shows that trucks on genuine Shacman steering tanks have 80% fewer steering pump failures and 60% lower fluid consumption. For any fleet manager, the genuine tank is the only intelligent choice.

Total Cost of Ownership – Fleet Example

A fleet of 100 Shacman X5000 trucks each covering 200,000 km per year will replace steering oil tanks approximately every 3 years. Using genuine DZ95189470086 tanks costs about 25% more than generic, but they last 2.5 times longer. Annual savings: $12,000 in fewer replacements, $22,000 in reduced pump repairs, $15,000 in less downtime, and $8,000 in lower fluid and filter costs. Over five years, net saving exceeds $285,000. Additionally, genuine tanks have a higher resale value as cores. The numbers prove it – genuine Shacman is the value choice.
