3408100

Designed as an OEM-compliant replacement part, this directional control pump oil tank 3408100 is exclusively engineered to fit a range of iconic     BYD models, including the Runner FORTUNER, Hilux HILUX, Innova INNOVA, as well as specific variants like F0 F3 F3R . Its precise design ensures seamless integration with the vehicle’s existing hydraulic system, aligning perfectly with the directional control pump—its designated installation location—to eliminate fitment issues and simplify maintenance or replacement processes.
Crafted from high-grade, impact-resistant engineering plastic (reinforced with glass fiber for enhanced durability), the tank boasts exceptional structural integrity to withstand the rigors of daily use, including under-hood temperature fluctuations (-30℃ to 80℃), vibration during off-road or heavy-duty driving, and potential minor impacts. The material also features excellent chemical resistance, preventing degradation from hydraulic oil and ensuring long-term compatibility with BYD’s recommended fluid specifications.
Functionally, this oil tank serves as a critical reservoir for the directional control pump, maintaining a consistent supply of clean hydraulic oil to support smooth operation of the vehicle’s steering or auxiliary hydraulic systems (e.g., power steering for Hilux or Innova). It incorporates a precision-molded internal baffle design that minimizes oil sloshing during vehicle movement, preventing aeration and ensuring stable oil pressure—key to avoiding pump cavitation and extending the lifespan of hydraulic components. Additionally, the tank’s sealed cap (included as part of the assembly) features a built-in breather valve to regulate internal pressure, preventing oil leaks while allowing air exchange to accommodate oil expansion and contraction.
Every unit undergoes strict quality testing, including pressure leakage tests and dimensional accuracy checks, to meet BYD original equipment standards. Whether for fleet maintenance, aftermarket replacement, or repair of aging components, this directional control pump oil tank delivers reliable performance, preserves the vehicle’s hydraulic system efficiency, and ensures consistent handling—making it an ideal choice for BYD owners and professional automotive service providers worldwide.
