Nikonos O-Ring Maintenance: A Step-by-Step Guide

The Nikon Nikonos is a legendary underwater camera known for its durability and reliability. However, like any mechanical device, it requires regular maintenance to ensure optimal performance and prevent leaks. One crucial aspect of Nikonos maintenance is the care of its O-rings, which are essential for keeping the camera watertight.

This guide provides a detailed walkthrough of how to properly remove, clean, and maintain the O-rings of your Nikonos camera. By following these steps, you can ensure your camera remains leak-proof and continues to deliver stunning underwater images.

Tools and Materials

• Small Phillips head screwdriver
• Q-tips
• Isopropyl alcohol (90% or higher)
• Silicone grease (specifically designed for O-rings)
• A clean, lint-free cloth

Step 1: Disassembly

Start by removing the camera body from the housing. Then, carefully detach the housing back. The O-rings are located in various points throughout the housing, including the back, the front port, and the lens mount.

To remove the O-rings, use your fingers or a small flat-head screwdriver to gently pry them out. Be careful not to damage the O-rings or the housing during this process.

Step 2: Cleaning

Once the O-rings are removed, clean them thoroughly with isopropyl alcohol using Q-tips. This will remove any dirt, debris, or old grease that could interfere with their sealing ability.

After cleaning, allow the O-rings to air dry completely.

Step 3: Lubrication

Apply a thin layer of silicone grease to the O-rings. This grease helps to create a smooth, watertight seal and prevents the O-rings from becoming brittle or dry.

Do not use too much grease, as this can attract dirt and debris, compromising the seal.

Step 4: Reassembly

Carefully re-install the O-rings into their designated positions. Ensure that they are properly seated and that there are no gaps or wrinkles.

Reassemble the housing and camera body, ensuring that all screws are tightened securely.

Step 5: Testing

Before taking your Nikonos underwater, it is crucial to test for leaks. Fill a sink or bathtub with water and submerge the camera. Observe for any leaks or bubbles.

If you notice any leaks, repeat the cleaning and lubrication process for the affected O-ring. If the leak persists, it may be necessary to replace the O-ring.

Maintenance Tips

• Clean and lubricate the O-rings after each dive.
• Inspect the O-rings for signs of wear or damage, replacing them as needed.
• Store the Nikonos in a dry, cool environment when not in use.

By following these maintenance tips, you can ensure that your Nikonos camera remains watertight and functions flawlessly for many years to come.

Remember, proper O-ring maintenance is crucial for the longevity and performance of your Nikonos camera. By taking the time to clean and lubricate these essential seals, you can continue to capture stunning underwater images with confidence.
