2. Produktet er slutview
The Park Tool DCW series cone wrenches are designed with a thin profile to fit into the narrow spaces of bicycle hub cones and locknuts. This kit includes four double-ended wrenches, providing a comprehensive range of sizes for various bicycle hub types.
- DCW-1: 13 mm og 14 mm
- DCW-2: 15 mm og 16 mm
- DCW-3: 17 mm og 18 mm
- DCW-4: 13 mm og 15 mm
Each wrench is constructed from durable alloy steel, ensuring reliability and precision for bicycle maintenance tasks.
3. Opsætning
Before beginning any hub adjustment, ensure you have a clean and well-lit workspace. Gather all necessary tools, including the appropriate cone wrenches from this kit, a standard box-end wrench (often 17mm or larger, depending on the locknut), and any required lubricants or cleaning supplies. It is recommended to remove the wheel from the bicycle for easier access and better leverage.
4. Operating Instructions: Adjusting Bicycle Hubs
Bicycle wheel hubs typically consist of an axle, bearings, cones, and locknuts. The cone wrenches are specifically designed to fit the thin profile of the cones, allowing for precise adjustment of bearing play.
- Identify Cone and Locknut: Locate the cone (the inner nut that presses against the bearings) and the locknut (the outer nut that secures the cone's position) on your wheel's axle.
- Select Correct Wrench Sizes: Choose the appropriate cone wrench for the cone and a standard box-end wrench for the locknut. Common cone sizes are 13mm, 15mm, and 17mm.
- Loosen Locknut: Using the standard wrench on the locknut and a cone wrench to hold the cone, loosen the locknut. This will allow the cone to be adjusted.
- Adjust Cone: With one cone wrench holding the cone, carefully turn it to adjust the bearing play. The goal is to eliminate any side-to-side play in the axle while ensuring the wheel spins freely without binding. The adjustment should be smooth, not loose.
- Spænd låsemøtrikken: Once the desired adjustment is achieved, hold the cone firmly in place with the cone wrench and tighten the locknut against it with the standard wrench. This locks the cone's position.
- Bekræft justering: Re-check the wheel for any play and ensure it spins smoothly. If there is still play or if the wheel binds, repeat the adjustment process.

5. Vedligeholdelse
To ensure the longevity and optimal performance of your Park Tool cone wrenches:
- Rensning: After each use, wipe the wrenches clean with a rag to remove any grease, dirt, or debris.
- Opbevaring: Store the wrenches in a dry environment to prevent rust. A tool roll or pegboard is ideal for organized storage.
- Inspektion: Periodically inspect the wrenches for any signs of wear, bending, or damage. While made from durable alloy steel, extreme force or improper use can cause deformation.
6. Fejlfinding
- Wrench Slipping: Ensure the correct size wrench is fully engaged with the cone. If the cone is rounded or damaged, it may need replacement.
- Wheel Still Has Play After Adjustment: The cone may not be tightened sufficiently against the bearings, or the locknut may not be adequately secured. Re-adjust, ensuring the cone is snug but not overtightened, and the locknut is firm.
- Wheel Binds After Adjustment: The cone is likely overtightened, causing excessive pressure on the bearings. Loosen the cone slightly and re-tighten the locknut.
- Difficulty Loosening Locknut: If the locknut is seized, apply a penetrating oil and allow it to soak before attempting to loosen again. Use firm, steady pressure.
