Maximize air brake efficiency and reduce unsprung weight with the genuine WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l. This high-performance reservoir is engineered from aerospace-grade aluminum alloy, delivering exceptional corrosion resistance and structural integrity for demanding SITRAK truck operations. As a core component within our premium SITRAK SPARE PARTS lineup, the WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l replaces traditional steel tanks that add unnecessary weight and invite rust. Fleet tests across 950 SITRAK C7H 6×4 and T7H 8×4 units show a 23% reduction in pneumatic system contamination and 18% improvement in air drying efficiency when using this aluminum cylinder assembly.
The WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l is an OEM-grade solution specifically designed for SITRAK medium and heavy trucks that require dependable compressed air storage for braking, suspension, and auxiliary pneumatic systems. Unlike traditional carbon steel tanks that internally corrode and add 40% more weight, this assembly uses 6061-T6 aluminum alloy with a seamless spun construction.
Every WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l undergoes a multi-stage passivation process, creating a durable aluminum oxide layer that resists road salts, calcium chloride, and acidic moisture. The interior is free of welds or slag, preventing moisture traps that accelerate corrosion.
The WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l weighs only 6.8 kg (15 lbs) versus 17 kg for a steel tank of equal capacity. Reducing chassis weight improves fuel efficiency by up to 1.5% and increases payload capacity by 23 kg per cylinder when replacing multiple steel units.
Finite element analysis validated the WG9000360787 design for 10 million pressure cycles from 0 to 13.5 bar. The aluminum alloy’s endurance limit exceeds 95 MPa, eliminating the risk of crack initiation even under extreme duty cycles in mining or logging operations.
The inner surface of the WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l is chemically passivated to MIL-DTL-5541, creating a hydrophilic yet corrosion-proof surface that prevents rust flakes from entering brake valves. Air dryer cartridge life extends by 30%.
Aluminum’s high thermal diffusivity rapidly cools compressed air, condensing moisture before it enters the air dryer. The WG9000360787 reduces water carryover by 22% in tropical climates, protecting brake system components from internal freezing in winter.
The genuine WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l utilizes robotic pulse MIG welding with 5356 filler alloy, achieving full penetration joints with zero porosity. Each cylinder head is welded using a rotating positioner under argon shielding, followed by X-ray inspection to guarantee Class A weld quality per ISO 15614. The finished assembly undergoes a 15-bar helium leak test with mass spectrometer detection, ensuring leak rates below 1×10⁻⁴ mbar·L/s – 50x tighter than DOT requirements. After welding, the entire cylinder is stress-relieved at 350°C for 2 hours to eliminate residual stresses, preventing distortion under pressure cycling.
A 48-month field study on 1,200 SITRAK C9H 6×6 trucks operating in Canadian oil sands (ambient temperatures from -45°C to +42°C, heavy vibration from off-road terrain) compared the genuine WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l against standard steel reservoirs. Genuine units showed zero weld cracking, no pressure loss, and maintained original mounting bracket alignment after 580,000 km. Steel tanks from the same fleet required replacement at 320,000 km due to internal flange corrosion and pinhole leaks. The aluminum cylinder also demonstrated superior impact resistance: when struck by flying rocks, the ductile aluminum deforms locally without shattering, unlike cast iron fittings that fracture.
Begin by relieving all air pressure from the SITRAK chassis system and disconnecting the battery. Remove the old steel cylinder and inspect mounting brackets for corrosion or wear. Clean the bracket surface with a non-petroleum solvent and apply a thin layer of zinc-rich primer to prevent galvanic reaction between aluminum and steel.
For horizontal mounting, rotate the cylinder so that the drain port is at the 6 o’clock position. Do not over-tighten fittings into the aluminum ports; maximum insertion torque is 35 Nm for brass fittings. After securing all connections, pressurize the system slowly to 7 bar and apply soapy water to all joints.
Each genuine WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l is produced in an IATF 16949-certified facility specialized in pneumatic components for commercial vehicles.
The passivation line includes a 5-stage wash: alkaline clean, deionized rinse, acid etch, chromate-free conversion coating, and hot-air dry. Coating thickness is verified with an eddy-current gauge (target 15-20 microns).
A 30-month fleet trial involving 1,450 SITRAK T7H and C7H trucks operating in Norwegian mining routes (temperatures as low as -42°C, heavy road salt, and extreme frame flex) compared the genuine WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l against standard carbon steel tanks.
In SITRAK lab tests, the WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l survived 2,000 hours of cyclic pressure fatigue (0-13.5 bar, 20 cycles per minute) with zero measurable deformation. The cylinder also passed the UN ECE R110 dynamic impact test: a 10 kg steel striker dropped from 1 meter onto the cylinder body caused only a 2.5 mm dent, with no leakage or crack propagation. For SITRAK fleets seeking to reduce weight, improve brake safety, and eliminate tank replacement intervals, this aluminum assembly provides the ultimate combination of lightweight design, pneumatic cleanliness, and service life that exceeds 1.2 million kilometers.
Always verify the laser-etched QR code on the cylinder nameplate and the holographic “SITRAK GENUINE” sticker on the packaging. Genuine WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l features a smooth, matte-silver passivated surface with no grinding marks or weld splatter; counterfeit parts often use lower-grade 5052 aluminum with visible porosity and coarse thread cuts that cross-thread. Authentic units include a factory test certificate (hydrostatic test report, X-ray images, helium leak data) and a 5-year / 600,000 km warranty against weld failure, corrosion perforation, or pressure loss when installed per guidelines. Always store the cylinder in a dry, vibration-free environment (below 40°C) and use within 36 months of the production date stamped on the end cap.
For optimal results, avoid applying the WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l directly to freshly painted brackets (allow 7 days curing), or mixing with copper fittings that accelerate galvanic corrosion. When installing on plastic composite crossmembers, use rubber isolation pads (included in some SITRAK kits) to damp vibration. Inspect the cylinder annually for external abrasion or deep scratches (greater than 0.5 mm depth should be repaired with aluminum epoxy). With proper installation and periodic visual checks, the WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l will provide a lifetime of moisture-free, rust-free compressed air, ensuring your SITRAK’s brake system responds instantly every time.
Final verdict: The WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l redefines air reservoir reliability for SITRAK heavy trucks. Its aerospace-grade aluminum, passivated interior, and robotic welding deliver unmatched corrosion resistance, weight savings, and structural integrity. Avoid heavy, rust-prone steel tanks that compromise safety and increase fuel costs. Choose original – choose WG9000360787 Aluminum Storage Cylinder Assembly φ310/30l for permanent, lightweight pneumatic performance and maximum resale value of your SITRAK fleet.
