2. Safety Information

WARNING: Improper installation or adjustment of suspension components can lead to loss of control, serious injury, or death. If you are not confident in your mechanical abilities, seek assistance from a qualified motorcycle mechanic.

• Always ensure the motorcycle is securely supported on a stable stand before beginning any work on the suspension.
• Wear appropriate personal protective equipment, including safety glasses and gloves.
• Never work under a motorcycle supported only by a kickstand or side stand.
• Refer to your motorcycle's service manual for specific torque specifications and procedures for removing and installing suspension components.
• Keep hands and clothing clear of moving parts.

4. Setup and Installation

This section provides general guidelines for installing the Ohlins S36PR1C1 shock absorber. Always consult your Honda SH 300 service manual for detailed, model-specific instructions.

4.1. Preparation

1. Park the motorcycle on a firm, level surface.
2. Securely lift the rear of the motorcycle using a suitable stand to allow the rear wheel to hang freely and relieve tension on the existing shock absorber.
3. Gather all necessary tools, including wrenches, sockets, and a torque wrench.

4.2. Removal of Original Shock Absorber

1. Locate the upper and lower mounting bolts of the original shock absorber.
2. Support the swingarm to prevent it from dropping suddenly when the shock is removed.
3. Carefully remove the mounting bolts. You may need to slightly raise or lower the swingarm to align the bolt holes.
4. Remove the original shock absorber from the motorcycle.

4.3. Installation of Ohlins S36PR1C1

1. Position the Ohlins S36PR1C1 shock absorber in its mounting location. Ensure any bushings or spacers are correctly oriented.
2. Insert the upper and lower mounting bolts. Hand-tighten them initially. Do not fully tighten at this stage.
3. Once both bolts are in place, refer to your Honda SH 300 service manual for the correct torque specifications for the shock absorber mounting bolts.
4. Using a torque wrench, tighten all mounting bolts to the specified torque.
5. Carefully lower the motorcycle from the stand.

4.4. Post-Installation Check

1. Ensure all bolts are tightened to specification.
2. Check for proper clearance between the shock absorber and other motorcycle components throughout the full range of suspension travel.
3. Perform an initial static sag measurement and adjust the spring preload as described in the 'Operating / Adjustment' section.

5. Operating and Adjustment

The Ohlins S36PR1C1 shock absorber offers precise adjustments to tailor your ride. Always make adjustments in small increments and test the motorcycle's handling in a safe environment.

5.1. Spring Preload Adjustment

Spring preload controls the initial compression of the spring, which directly affects the motorcycle's ride height and static sag. Correct static sag is crucial for optimal suspension performance.

1. Locate the preload adjustment collar on the shock absorber.
2. Use the appropriate tool (often a C-spanner) to turn the adjustment collar.
3. Turning the collar clockwise increases spring preload, resulting in a stiffer ride and higher ride height.
4. Turning the collar counter-clockwise decreases spring preload, resulting in a softer ride and lower ride height.
5. Adjust until the desired static sag is achieved. Refer to your motorcycle's service manual or Ohlins recommendations for ideal sag settings.

5.2. Compression Damping Adjustment

Compression damping controls the resistance to the shock absorber's compression movement, influencing how quickly the shock compresses when encountering bumps or during braking.

1. Locate the compression damping adjuster, typically a knob or screw, often found at the top or bottom of the shock body or reservoir.
2. Turning the adjuster clockwise increases compression damping, making the ride firmer and slowing down the compression stroke.
3. Turning the adjuster counter-clockwise decreases compression damping, making the ride softer and allowing faster compression.
4. Start with the manufacturer's recommended settings (if available) and adjust based on your riding style, weight, and road conditions.

Note: Always record your current settings before making changes to easily revert to a known good setup.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your Ohlins shock absorber.

• Regular Cleaning: Keep the shock absorber clean, especially the piston rod, to prevent dirt and debris from entering the seals. Use mild soap and water, then rinse thoroughly. Avoid using high-pressure washers directly on the seals.
• Inspection: Periodically inspect the shock absorber for any signs of oil leakage, damage to the spring, or wear on the bushings and mounting points.
• Bolt Torque: Check the torque of the mounting bolts periodically, especially after the first few rides, to ensure they remain tightened to specification.
• Professional Service: If you notice significant oil leakage, unusual noises, or a degradation in performance, the shock absorber may require professional servicing by an authorized Ohlins service center.

7. Troubleshooting

This section addresses common issues you might encounter with your shock absorber.

• Excessive Bottoming Out: If the shock absorber frequently reaches its maximum compression, consider increasing the spring preload or increasing the compression damping.
• Harsh or Stiff Ride: If the ride feels excessively harsh, try decreasing the spring preload or decreasing the compression damping.
• Poor Handling or Instability: Verify that the spring preload and damping settings are appropriate for your weight and riding conditions. Ensure all mounting bolts are properly torqued. Inspect for any signs of damage or wear on the shock or other suspension components.
• Oil Leakage: Any visible oil leakage from the shock absorber indicates a seal failure. The unit requires immediate professional inspection and servicing. Do not continue to ride with a leaking shock absorber.
