تنصیب کی ہدایات
- گاڑی تیار کریں: Safely lift and support the vehicle using jack stands or a hydraulic lift. Ensure the suspension is unloaded.
- Remove Old Shocks: Locate and remove the existing shock absorbers. This typically involves unbolting the upper and lower mounting points. Retain any reusable hardware if applicable.
- ماؤنٹنگ پوائنٹس کا معائنہ کریں: Clean and inspect the vehicle's shock mounting points for any damage, corrosion, or wear. Repair as necessary.
- Install New Shocks:
- Install the provided polyurethane bushings or bearing mounting hardware onto the QA1 TD902 shock.
- Position the new shock absorber into the upper mounting point and secure it with the appropriate hardware. Do not fully tighten at this stage.
- Extend or compress the shock as needed to align with the lower mounting point. Secure with hardware.
- ٹارک فاسٹنر: With the vehicle's weight on the suspension (or at ride height), tighten all mounting bolts to the vehicle manufacturer's specified torque values. Refer to your vehicle's service manual.
- فائنل چیک: Double-check all fasteners for proper torque. Ensure there is no interference with other suspension or vehicle components.
نوٹ: For coil-over applications, specific coil-over hardware will be included and should be installed according to the separate coil-over instructions.
ایڈجسٹمنٹ اور آپریشن
The QA1 TD902 is a double adjustable shock, allowing independent control over compression (bump) and rebound (extension) damping. This enables fine-tuning of your vehicle's ride and handling characteristics.
ایڈجسٹمنٹ کا طریقہ کار:
- Locate Adjusters: The shock features two adjustment knobs, typically located at the bottom of the shock body. One knob controls compression, and the other controls rebound. Refer to the markings (e.g., 'C' for Compression, 'R' for Rebound) on the shock body.
- ابتدائی ترتیب: It is recommended to start with both compression and rebound adjusters set to a neutral or manufacturer-recommended baseline. This is often achieved by turning the knob fully counter-clockwise until it stops (zero clicks), then turning it clockwise a specified number of clicks. Consult QA1 documentation for specific baseline settings if available.
- Adjusting Compression: Turning the compression knob clockwise increases the damping force during shock compression (when the wheel moves upwards). This can help control body roll and dive.
- Adjusting Rebound: Turning the rebound knob clockwise increases the damping force during shock extension (when the wheel moves downwards). This helps control how quickly the wheel returns to its original position after hitting a bump, improving tire contact with the road.
- اضافی ایڈجسٹمنٹ: Make small adjustments (1-2 clicks at a time) and test the vehicle's behavior. Note your settings for future reference.
- ہم آہنگی: Ensure that adjustments are made symmetrically across the vehicle (e.g., both front shocks, or both rear shocks) unless specific tuning requires otherwise.
ٹپ: Keep a log of your adjustment settings and how they affect vehicle performance to find your optimal setup for different driving conditions.
دیکھ بھال
Regular maintenance helps ensure the longevity and optimal performance of your QA1 TD902 shock absorbers.
- باقاعدہ معائنہ: Periodically inspect the shocks for any signs of leaks, damage to the body or piston rod, or worn bushings.
- صفائی: Keep the shock bodies and piston rods clean, especially after driving in dirty or corrosive conditions. Use mild soap and water, then rinse thoroughly. Avoid harsh chemicals that could damage seals.
- ہارڈ ویئر چیک: Verify that all mounting hardware remains tight and secure. Re-torque fasteners to specification if necessary.
- Piston Rod Protection: Avoid scratching or damaging the piston rod surface, as this can lead to seal failure and fluid leaks.
- جھاڑیاں: Inspect polyurethane bushings for cracking or excessive wear. Replace them if they show signs of degradation.
خرابی کا سراغ لگانا
If you experience issues with your QA1 TD902 shock absorbers, consult the following common troubleshooting steps:
| علامت | ممکنہ وجہ | حل |
|---|---|---|
| Excessive Bouncing/Poor Ride Control | غلط ڈیamping settings (too soft), worn shock, insufficient spring rate. | Increase compression and/or rebound damping. Inspect for leaks or damage. Consult a suspension specialist. |
| Harsh Ride/Stiff Suspension | غلط ڈیamping settings (too stiff), incorrect spring rate. | Decrease compression and/or rebound damping. Ensure adjustments are symmetrical. |
| Fluid Leaks from Shock Body | Damaged seal, bent piston rod, internal component failure. | A leaking shock requires replacement or professional rebuilding. Contact QA1 support. |
| جھنجھلاہٹ یا جھنجھلاہٹ کا شور | Loose mounting hardware, worn bushings, internal shock damage. | Check and re-torque all mounting bolts. Inspect bushings for wear. If noise persists, inspect the shock for internal damage. |
If these steps do not resolve the issue, contact QA1 technical support for further assistance.
