786 - Replacement chain tool pin for IB-3

The Park Tool 786 Replacement Chain Tool Pin is a genuine service part specifically designed for use with the Park Tool IB-3 Chain Breaker/Pin Press. This precision-engineered pin replaces worn or damaged pins in the IB-3 mechanism, restoring smooth, reliable chain breaking and pin pressing performance.

Manufactured from hardened, durable steel, the 786 pin withstands the repeated force and torque required to push chain pins in and out of 8-, 9-, 10-, 11-, and 12-speed chain designs (as compatible with the IB-3). Over time, the original pin can wear, mushroom, or dull, leading to inefficient operation or risk of damage to the tool or chain. Installing this replacement pin brings the IB-3 back to its intended precision and makes chain maintenance safer and more effective.
