4. Setup and Installation
Installation of the OHLINS Rear Suspension Twin S36P should be performed by a qualified technician using appropriate tools and safety procedures. Incorrect installation can lead to serious injury or damage to the motorcycle.
General Installation Steps (Consult a service manual for your specific motorcycle model):
- Ensure the motorcycle is securely supported on a stand, with the rear wheel off the ground.
- Remove the original rear shock absorbers. Note the orientation and any spacers.
- Carefully position the OHLINS S36P shock absorbers, ensuring correct orientation of the upper and lower mounts.
- Install the mounting bolts and nuts. Do not fully tighten at this stage.
- Once both shocks are in place, tighten all mounting bolts to the torque specifications provided in your motorcycle's service manual.
- Verify that there is no interference with other motorcycle components throughout the full range of suspension travel.
- Perform a final check of all fasteners to ensure they are securely tightened.
Note: The S36P model features a piggyback reservoir. Ensure adequate clearance for the reservoir during installation and throughout suspension travel.
5. Operating Instructions and Adjustments
The OHLINS S36P rear suspension is designed for optimal performance with minimal user adjustment. This model features preload adjustment only.
Preload Adjustment:
The spring preload can be adjusted using the stepless screw type mechanism. Adjusting preload changes the initial compression of the spring, affecting ride height and sag. This adjustment should be made to achieve the recommended sag for your weight and riding style.
- To increase preload (stiffer ride, higher ride height), turn the adjustment ring clockwise.
- To decrease preload (softer ride, lower ride height), turn the adjustment ring counter-clockwise.
Always adjust both shock absorbers equally. Refer to a motorcycle suspension tuning guide for detailed instructions on setting sag.
6. Maintenance
Proper maintenance ensures the longevity and performance of your OHLINS suspension. Regular inspection and cleaning are crucial.
Recommended Maintenance:
- Cleaning: Regularly clean the shock absorbers with mild soap and water to remove dirt, dust, and road grime. Avoid high-pressure washers directly on seals.
- Inspection: Periodically inspect for any signs of oil leakage, damage to the spring, shaft, or reservoir, and wear on mounting bushings.
- Fastener Checks: Ensure all mounting bolts and nuts remain securely tightened.
- Professional Service: OHLINS shock absorbers contain high-pressure gas and should only be serviced by authorized OHLINS service centers. Do not attempt to disassemble the shock absorber yourself.
7. Troubleshooting
If you experience issues with your OHLINS suspension, consider the following common points before seeking professional assistance.
| Symptom | Possible Cause | Solution |
|---|---|---|
