Arriba 5 Signs Your Sinotruk Truck Needs Storage Tank Upper Mount Repairs
1. Visible Cracks or Rust on the Mounting Bracket
What to Look For:
• Hairline fractures along the steel or aluminum mounting brackets
• Reddish-brown streaks indicating oxidation
• Warping or bending of the attachment points
Por qué es importante:
El storage tank upper mount supports heavy loads (arriba a 200 kg) and withstands constant vibration. Cracks compromise load distribution, risking sudden detachment during transit. Corrosion from road salt or harsh environments accelerates weakening over time.
Pro Tip:
Perform a monthly inspection using a flashlight to spot early-stage damage. Our OEM-grade WG9925560810 replacements include corrosion-resistant stainless steel plates, extending component lifespan by 300%.

2. Unusual Noises During Operation
Identify the Sounds:
• High-pitched squeaking when braking or accelerating
• Clunking noises when turning corners
• Fluid sloshing sounds despite sealed systems
Technical Insight:
Loose bolts or worn-out bearing pads within the upper mount assembly cause these noises. Over time, misalignment shifts the storage tank, straining connecting rods and hydraulic lines.
Solution:
Our technicians use laser alignment tools to restore precise positioning. Replacing worn-out urethane bushes (part #WG9925560810) with reinforced polymer inserts reduces noise by 80%.
3. Leaks Around the Urine Box Area
Common Leak Points:
• Seams where the tank meets the mounting bracket
• Bolt holes showing signs of salt deposits
• Hydraulic line connections near the upper mount
Diagnostic Steps:
1. Perform a dye test to identify micro-leaks
2. Check for rusted or stripped threads on mounting bolts
3. Inspect O-rings for UV damage (critical in regions with high UV exposure)
Preventative Maintenance:
Regular lubrication of guide pins (included in our repair kits) and applying anti-seize compound to bolt threads can prevent leaks. Our WG9925560810 kits come with torque specifications for proper tightening.
4. Reduced Hydraulic System Efficiency
Performance Metrics to Monitor:
• Increased fluid consumption (more than 10% per month)
• Delayed brake response due to fluid pressure loss
• Air bubbles in the hydraulic lines
Root Cause Analysis:
A compromised upper mount distorts the storage tank angle, creating air pockets in the hydraulic circuit. This reduces pressure delivery to the brakes and lifting mechanisms.
Engineering Fix:
Our OEM-certified replacement parts include a redesigned fluid channel guide (patented design #WG9925560810) that eliminates turbulence and maintains consistent pressure flow. Field tests show a 25% improvement in brake system responsiveness.
5. Visible Misalignment of Storage Tank
Visual Inspection Checklist:
• The tank leans more than 2° from vertical
• Uneven tire wear patterns (indicating weight shift)
• Obstructed access panels for maintenance
Consequences of Misalignment:
• Uneven brake wear (costing up to $500 per tire pair annually)
• Premature failure of suspension components
• Safety hazards from protruding tank edges
Precision Repair Process:
Using 3D laser scanning, our technicians measure the tank’s position relative to the chassis. We then realign it using adjustable support brackets (part of the WG9925560810 kit) and torque-locking hardware to maintain factory tolerances.
