3. Setup (Installation)
Before beginning installation, ensure you have the correct tools and a stable working environment. It is highly recommended to have this product installed by a certified mechanic.
3.1 Pre-Installation Checks
- Verify that the suspension model (S36E HD145) is compatible with your specific SPORTSTER model and year.
- Inspect the new suspension units for any signs of damage from shipping.
- Gather all necessary tools, including a motorcycle lift or stand, wrenches, torque wrench, and appropriate safety gear.
3.2 Installation Procedure (General Guidelines)
- Secure the motorcycle on a stable stand, ensuring the rear wheel is off the ground.
- Carefully remove the original rear shock absorbers, noting the orientation and any spacers.
- Install the OHLINS S36E HD145 units, ensuring all mounting bolts are correctly aligned and tightened to the manufacturer's specified torque values. Refer to your motorcycle's service manual for specific torque settings.
- Ensure proper clearance around the suspension units and moving parts.
- Lower the motorcycle and perform a static sag measurement to determine initial preload settings.
4. Operating (Adjustments)
The OHLINS S36E HD145 allows for preload adjustment to fine-tune the suspension for rider weight and riding conditions.
4.1 Preload Adjustment
The cam-lock preload adjuster allows for 3-stage adjustment of the spring preload. This adjustment affects the ride height and initial compression of the spring.
- To adjust, first ensure the motorcycle is stable and the suspension is unloaded.
- Locate the cam-lock mechanism on the shock body.
- Unlock the mechanism (specific method may vary, refer to detailed OHLINS instructions if provided with the product).
- Rotate the cam to select one of the three preload settings.
- Relock the mechanism securely after adjustment.
Note: Always adjust both left and right shock absorbers equally to maintain balanced handling.
5. Maintenance
Regular maintenance is essential to ensure the longevity and performance of your OHLINS suspension.
- Cleaning: Regularly clean the shock absorbers with mild soap and water to remove dirt, grime, and road salt. Avoid high-pressure washers directly on seals.
- Inspection: Periodically inspect the shock bodies, springs, and mounting points for any signs of damage, leaks, or wear. Check bolts for proper torque.
- Service: OHLINS recommends periodic servicing by an authorized service center. Consult your OHLINS dealer for recommended service intervals based on your riding conditions.
6. Troubleshooting
If you experience issues with your suspension, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Poor ride quality / Too stiff | Incorrect preload setting | Adjust preload to a softer setting. Ensure both shocks are set equally. |
| Excessive bottoming out | Insufficient preload | Increase preload. If problem persists, professional re-valving may be required. |
| Unusual noises (clunking, squeaking) | Loose mounting bolts, worn bushings, internal issue | Check all mounting bolts for proper torque. Inspect bushings. If noise persists, seek professional inspection. |
| Oil leakage from shock body | Damaged seal, internal component failure | Stop riding immediately. Contact an authorized OHLINS service center for repair. |
