Safety Information
Always prioritize safety. Improper installation or use can lead to serious injury or damage to the vehicle. It is highly recommended that installation and major adjustments be performed by a qualified technician with experience in suspension systems.
- Wear appropriate personal protective equipment (PPE) during installation.
- Ensure the vehicle is securely supported before working on the suspension.
- Do not attempt to disassemble the shock absorber unless specifically instructed by Ohlins service documentation, as it contains high-pressure gas.
- Refer to your vehicle's service manual for specific torque specifications and procedures.
Setup and Installation
The Ohlins HD775 S36E Shock Absorber is designed for specific vehicle applications (ATV, UTV). Ensure this product is compatible with your vehicle before proceeding.
Pre-Installation Check
- Verify that all components are present and undamaged.
- Confirm the shock absorber's length and mounting points match your vehicle's requirements.
Mounting Instructions
- Safely lift and support the vehicle according to its service manual.
- Remove the existing shock absorbers. Note the orientation of the original shocks.
- Install the Ohlins HD775 S36E shock absorber, ensuring the mounting eyes are correctly aligned.
- Tighten all mounting bolts to the vehicle manufacturer's specified torque settings. Do not overtighten.
- Lower the vehicle carefully.
Initial Adjustments (Pre-load)
The HD775 S36E model features a simple design, primarily allowing for spring pre-load adjustment. This adjustment affects the ride height and initial stiffness.
- To adjust pre-load, use the supplied C-spanner wrench to rotate the spring collar.
- Increasing pre-load (compressing the spring) will raise the ride height and make the suspension feel stiffer.
- Decreasing pre-load (decompressing the spring) will lower the ride height and make the suspension feel softer.
- Always adjust both shock absorbers equally to maintain balance.
- Consult an Ohlins authorized service center or a qualified technician for optimal pre-load settings for your specific riding style and load.
Operating Considerations
Once installed, the Ohlins HD775 S36E shock absorber will significantly enhance your vehicle's handling and ride quality. While designed for durability, proper operation ensures longevity.
- Break-in Period: Allow for a short break-in period (e.g., 50-100 miles) for the shock components to settle.
- Load Management: Be mindful of your vehicle's load capacity. Overloading can compromise shock performance and lifespan.
- Driving Conditions: While robust, extreme off-road conditions or continuous heavy impacts can accelerate wear.
Maintenance
Regular maintenance is crucial for the performance and longevity of your Ohlins shock absorbers.
Routine Checks
- Cleaning: Keep the shock absorbers clean, especially the shaft and seals. Use mild soap and water, then rinse thoroughly. Avoid high-pressure washers directly on seals.
- Visual Inspection: Regularly check for signs of oil leakage, damage to the spring, body, or mounting points. Look for bent shafts or worn bushings.
- Fastener Torque: Periodically check that all mounting bolts are tightened to the correct torque specifications.
Service Intervals
Ohlins recommends regular servicing by an authorized service center. The frequency depends on usage:
- Normal Use: Every 10,000-15,000 miles or annually, whichever comes first.
- Heavy/Off-Road Use: More frequent servicing, potentially every 5,000 miles or semi-annually.
Servicing typically includes fluid replacement, seal inspection/replacement, and nitrogen gas recharge.
Troubleshooting
If you experience issues with your Ohlins HD775 S36E shock absorbers, refer to the following common problems and solutions. For complex issues, contact an authorized Ohlins service center.
| Problem | Possible Cause | Solution |
|---|---|---|
| Poor Ride Quality / Excessive Bouncing | Incorrect pre-load setting, worn components, low fluid/gas pressure. | Check and adjust pre-load. Inspect for leaks or damage. Professional service may be required. |
| Oil Leakage | Damaged seals, bent shaft. | Stop using the shock immediately. Requires professional repair or replacement of seals. |
| Unusual Noises (e.g., clunking) | Loose mounting bolts, worn bushings, internal damage. | Check all mounting bolts for proper torque. Inspect bushings. If noise persists, seek professional inspection. |
| Uneven Ride Height | Unequal pre-load settings between shocks, damaged spring. | Ensure pre-load is set identically on both shocks. Inspect springs for damage. |
