EK Chain Tool - Pin #40, for CRT50AS

The EK Chain Tool - Pin #40, designed specifically for CRT50AS, is the precise replacement pin you rely on to keep EK chain tools performing at peak accuracy. When you’re servicing EK chains, a worn or misaligned pin can throw rivets off by a fraction, leading to inconsistent link pressure or premature wear. This pin brings back factory-fit reliability so you can trust every chain repair or lengthening job.

Why Pin #40 matters

• Precision-ground for EK chains: The Pin #40 is engineered to match the exact diameter and contact geometry required by CRT50AS tools, ensuring smooth, even rivet contact every time.
• Hardened for durability: Built from high-strength steel and heat-treated to resist wear, it maintains edge integrity through countless cycles of rivet setting and pin extraction.
• Consistent rivet depth: A correctly dimensioned pin supports uniform rivet depth, reducing the risk of over- or under-pivoting links and extending chain life.
• Efficient workflow: With a dependable pin, you’ll spend less time re-aligning parts and more time completing precise chain maintenance projects.

Who benefits most

Bike technicians, professional shops, and serious enthusiasts who regularly service EK chains with CRT50AS tooling will notice the difference. If you rely on precise rivet formation, minimal tool wear, and predictable results, Pin #40 is a worthy upgrade to your EK chain maintenance kit.

Practical use cases

• Replacing a worn rivet pin during routine EK chain maintenance, ensuring consistent link compression.
• Rebuilding or shortening EK chains where precise rivet seating is essential for smooth operation.
• Maintenance on CRT50AS setups where the original pin shows signs of wear or drift.

Compatibility and installation

This pin is a targeted replacement for the EK Chain Tool used with CRT50AS. For best results, pair Pin #40 with your CRT50AS tool as part of a dedicated EK chain maintenance workflow.

Care, maintenance, and tips

• Store in a dry environment to prevent corrosion and rust on the hardened surface.
• Inspect the pin before each use; replace if you notice rounding, chips, or visible wear on the tip.
• Clean the tool body after use to remove oil, residue, or metal shavings that could affect pin seating.
• Use a consistent driving force when setting rivets to maximize the pin’s life and maintain uniform rivet depth.
