The Shacman X5000 Expansion Tank Bracket Assembly is an OEM-grade mounting solution designed to securely fasten the expansion tank to the chassis of Shacman X5000 heavy trucks. This assembly ensures vibration isolation, proper alignment, and long-term durability. The complete kit consists of two precision components: Expansion Tank Bracket and Welded Hex Nut. Each part is engineered for extreme conditions, preventing coolant leaks caused by bracket fatigue.
| Part Number | Part Name |
|---|---|
| DZ97259538198 | Expansion Tank Bracket |
| Q370C08 | Welded Hex Nut |
Expansion Tank Bracket material: S500MC micro-alloyed steel, yield strength 620 MPa, tensile 750 MPa. Formed by CNC laser cutting and press brake.
Welded Hex Nut: M8x1.25 fine thread, height 8mm, width 13mm. Weld projection design ensures consistent fusion with bracket base metal.
Bracket thickness: 6.0 mm ±0.1 mm. Weight: 1.8 kg. Surface coating: ZnNi (12µm) + trivalent passivate + topcoat (silver gray).
Load capacity: Static 500 kg, dynamic ±2.5g (vertical) and ±1.5g (lateral). Safety factor 4:1 relative to max expected coolant tank load.
Operating temperature range: -50°C to +120°C. No embrittlement even after arctic exposure. Welded nut retains torque after thermal cycling.
Step 1: Position expansion tank bracket onto chassis side rail. Align with two existing M10 holes. Hand-start bolts through welded nuts.
Step 2: Place expansion tank onto bracket and secure using original tank bolts. Torque tank bolts to 25 Nm. Do not overtighten.
Step 3: Tighten chassis mounting bolts to 45 Nm ±5 Nm using a calibrated torque wrench. Apply medium thread locker for off-road use.
Step 4: Check that rubber isolators (if retrofitted) sit correctly in bracket groove. No metal-to-metal contact between tank and bracket.
Step 5: After first 500 km, re-torque all fasteners. Welded hex nuts will not rotate, ensuring consistent clamp load over time.
Vibration test: 80 hours random 5-500Hz, 3.5g RMS per ISO 16750-3. No cracks, no loosening of welded nuts, no deformation.
Salt spray test: 1000 hours ASTM B117 on full assembly. Bracket showed less than 2% white rust, no red rust. Welded nut threads unaffected.
Thermal cycle: 150 cycles from -40°C to +100°C. No change in weld integrity or nut retention torque. Coating adhesion unchanged.
Field trial on 200 X5000 trucks in Australian mines: after 18 months, zero bracket failures. Nut threads remained clean and functional.
Fatigue test: 2 million cycles at 120% nominal load. No crack initiation detected by magnetic particle inspection.
Inspect bracket every 100,000 km for paint chips or corrosion. Touch up with zinc-rich primer if necessary. Replace if any crack visible.
Check welded hex nuts for thread damage each time the expansion tank is removed. Chase threads with M8x1.25 tap if minor corrosion.
Retorque chassis bolts every 200,000 km. Use anti-seize compound on bolt threads to prevent galvanic corrosion between bolt and nut.
When replacing the expansion tank, always inspect bracket for straightness. Bent brackets cause uneven tank loading and premature failure.
For vehicles operating in severe salt environments, apply additional cavity wax to bracket welds and nut interfaces annually.
Aftermarket brackets often use 4mm mild steel (Q235) without ribs. They flex under load, cracking within 12 months. Genuine uses 6mm HSLA.
Generic Shacman X5000 Expansion Tank Bracket Assembly brackets lack welded hex nuts, requiring loose nuts and washers. These often fall off during assembly, causing lost hardware and delays.
Counterfeit brackets skip rubber isolator grooves, transmitting vibration directly to tank. Results in coolant leaks at hose connections.
Non-OEM coatings fail after 200h salt spray; genuine zinc-nickel lasts 1000h. Choosing genuine reduces replacement frequency by 4x.
Using authentic Shacman X5000 Expansion Tank Bracket Assembly maintains chassis warranty and prevents tank damage claims.
Designed for Shacman X5000 trucks with any engine (WP12, WP13, ISM11). Also fits X3000 and X6000 using same bracket pattern.
Replaces original part numbers DZ97259538198 and Q370C08 directly. No adapter needed for Euro V, Euro VI, or China VI models.
Compatible with both plastic and aluminum expansion tanks. The bracket includes slots for different tank foot designs.
For vehicles with auxiliary heater, bracket has an extra pre-drilled hole for mounting coolant valve bracket.
Each Shacman X5000 Expansion Tank Bracket Assembly is packed in a foam-lined carton. Includes bracket with pre-welded hex nuts and installation sheet.
Hardware bag: 2x M8x25 flange bolts (optional) and anti-seize packet. Bracket alone weighs 1.9 kg, carton dimensions 35x25x8 cm.
Stock locations: Houston, Dubai, Hamburg, Shanghai. Standard delivery 2-5 business days. Express freight available for emergency repairs.
Bulk orders (10+ units) receive palletized shipping and volume discount. Each bracket has laser-etched Shacman logo and date code.
24-month unlimited mileage warranty against manufacturing defects. Returns accepted within 30 days.
No, they are permanent. Replace the entire bracket if threads are stripped. However, nuts are class 10 hardened and very durable.
Yes, the bracket is independent of transmission type. Mounting holes are identical across all X5000 chassis variants.
The bracket itself includes a groove for optional rubber isolator pad (sold separately, part DZ93259590003). For most trucks, direct mounting works.
Maximum recommended torque is 45 Nm. Exceeding 60 Nm may distort the weld projection. Always use torque wrench.
Yes, the bracket is designed to coexist with urea tank brackets. No interference on standard X5000 layouts.
All Shacman X5000 Expansion Tank Bracket Assembly steel content is 100% recyclable. Coating contains no hexavalent chromium, complies with EU ELV Directive 2000/53/EC.
Welding process uses lead-free electrodes. No cadmium or mercury. RoHS 3 compliant (2015/863/EU).
Packaging cardboard made from 80% recycled fiber, fully biodegradable. No plastic blisters.
