4. Тохиргоо ба суурилуулалт
Proper installation is crucial for the performance and safety of your Ohlins shock absorbers. It is highly recommended that installation be performed by a qualified motorcycle technician. Incorrect installation can lead to damage to the product or the motorcycle, and may compromise rider safety.
Суурилуулалтын ерөнхий заавар:
- Бэлтгэл: Ensure the motorcycle is securely supported on a stand, with the rear wheel off the ground.
- Removal of Old Shocks: Carefully remove the existing rear shock absorbers, noting the orientation and any spacers.
- Installation of New Shocks: Install the Ohlins STX 36 Blackline Twin Shocks. Ensure all mounting bolts are torqued to the motorcycle manufacturer's specifications. Do not overtighten.
- Бүртгэлийн шалгалт: Verify that there is adequate clearance around the shock absorbers throughout the full range of suspension travel.
- Анхны тохируулга: While these shocks come pre-set, minor adjustments may be necessary based on rider weight and riding style. Refer to the motorcycle's service manual for general suspension setup principles.
Note: Specific torque values and detailed installation steps for your motorcycle model should be obtained from the official Harley-Davidson service manual.

5. Үйл ажиллагааны зарчим
The Ohlins STX 36 Blackline Twin Shocks are designed to provide superior damping and control. As monotube high-pressure gas type shock absorbers, they utilize an internal container within the main body to separate the oil from the gas, preventing cavitation and ensuring consistent damping performance under various conditions.
The 36mm piston diameter contributes to effective oil displacement, allowing for precise control over compression and rebound damping. The pre-set spring rate of 19 N/mm is optimized for the specified Harley-Davidson Sportster models, offering a balanced ride for typical use.
While these shocks are designed for performance, it is important to ride responsibly and within the limits of your motorcycle and riding conditions. Always wear appropriate safety gear.
6. Засвар үйлчилгээ
Regular maintenance extends the lifespan and ensures the optimal performance of your Ohlins shock absorbers. While Ohlins products are built for durability, periodic checks are recommended.
Зөвлөмж болгож буй арчилгаа:
- Тогтмол цэвэрлэгээ: Keep the shock absorbers clean from dirt, grime, and road debris. Use mild soap and water, then rinse thoroughly. Avoid high-pressure washers directly on seals.
- Нэвчилт байгаа эсэхийг шалгах: Periodically check for any signs of oil leakage around the seals. A small film of oil is normal, but excessive leakage indicates a problem.
- Check Mounting Bolts: Ensure all mounting bolts are secure and torqued to specification. Loose bolts can lead to premature wear or failure.
- Inspect Bushings: Check the condition of the mounting bushings for wear or cracking. Worn bushings can affect handling.
- Мэргэжлийн үйлчилгээ: For internal servicing, re-valving, or major repairs, always consult an authorized Ohlins service center or a qualified suspension specialist. Do not attempt to disassemble the shock absorber yourself, as it contains high-pressure gas.
7. Алдаа засах
This section addresses common issues that may arise with shock absorbers. For complex problems, professional assistance is advised.
| Асуудал | Боломжит шалтгаан | Шийдэл |
|---|---|---|
| Excessive Bounciness / Poor Damping | Worn internal components, low gas pressure, incorrect spring rate for load. | Inspect for leaks. If no leaks, professional service may be required to check internal components and gas pressure. Ensure correct spring for application. |
| Хатуу ширүүн жолоодлого / Дуулгаваргүй байдал | Incorrect spring rate (too stiff), binding in suspension linkage (if applicable). | Verify spring rate is appropriate for rider/load. Check motorcycle's swingarm pivot and linkage for free movement. |
| Нефтийн алдагдал | Damaged oil seal. | Contact an authorized Ohlins service center for seal replacement. Do not ride with leaking shocks. |
| Ер бусын чимээ (жишээ нь, чанга дуу чимээ) | Loose mounting bolts, worn bushings, internal damage. | Check all mounting bolts for proper torque. Inspect bushings for wear. If noises persist, seek professional inspection. |
