3. Setup and Installation
Proper installation is crucial for the performance and safety of your motorcycle. It is highly recommended that installation be performed by a qualified technician.
3.1. Pre-Installation Checks
- Ensure the shock absorber is the correct model (HD141) for your motorcycle.
- Inspect the shock for any visible damage from shipping.
- Gather all necessary tools, including a torque wrench, appropriate sockets, and a motorcycle lift or stand.
3.2. Installation Procedure (General Steps)
- Secure the motorcycle on a stable stand, ensuring the rear wheel is off the ground.
- Carefully remove the original shock absorber(s) by unbolting the upper and lower mounting points. Note the orientation of the original shocks.
- Install the Ohlins S36PL Shock Absorber, ensuring the external reservoir is positioned correctly according to your motorcycle's frame and clearance.
- Tighten the mounting bolts to the torque specifications provided in your motorcycle's service manual.
- Lower the motorcycle and check for proper clearance and function.
Note: Always refer to your motorcycle's specific service manual for detailed torque specifications and installation procedures.
4. Operating and Adjustment
The Ohlins S36PL shock absorber offers adjustable features to fine-tune your ride experience. These adjustments should be made incrementally and tested to achieve desired results.
4.1. Length Adjustment
The shock absorber features adjustable length. This adjustment affects the ride height and geometry of the motorcycle. Consult a professional for guidance on optimal length settings for your riding style and load.
4.2. Preload Adjustment
The spring preload can be adjusted to set the sag of the motorcycle. Proper sag is essential for optimal suspension performance. Use the provided tools (if any) or a suitable spanner wrench to adjust the spring collars. Turn clockwise to increase preload (stiffer), counter-clockwise to decrease (softer).
Caution: Do not over-tighten or loosen preload collars beyond their designed range. Incorrect preload can negatively affect handling and safety.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Ohlins shock absorber.
- Cleaning: Keep the shock absorber clean from dirt, dust, and road grime. Use mild soap and water, then rinse thoroughly. Avoid high-pressure washers directly on seals.
- Inspection: Periodically inspect the shock for any signs of oil leaks, damaged seals, bent shafts, or loose mounting bolts.
- Bushings and Bearings: Check the condition of the mounting bushings and bearings. Replace if there is excessive play or wear.
- Service Intervals: Ohlins recommends professional servicing of their shock absorbers at regular intervals, typically every 20,000 km or annually, depending on riding conditions. Refer to Ohlins' official documentation for specific service schedules.
6. Troubleshooting
