Applications
Chains sizes from small timing chain (min pin diameter 2.2mm) to heavy duty 630 chain.
Note: when separating chain sizes above 530 it is strongly advised the head of the rivet on the tool
side is ground off or filed off first.
Instructions
Note: Ensure all force screws and pins are adequately lubricated with oil or chain lubricant.
Breaking a Chain
1. Select the appropriate Force Pin from (F2), (G2), (H2) and (I2) according to the diameter of the
chain pin and fit the spring K over the pin as show in Fig 1.
2. Remove force screw (C) from the main screw (B) and fit the pin and spring as shown in Fig 1.
3. Refit force screw (C)
4. Fit appropriate size upper guide (F1, G1, H1, and I1) as shown in Fig 1.
5. Fit the tool body handle as shown and assemble as shown in Fig 2.
6. Remove the tool and reassemble using the most suitable anvil (L, M or N), the rivet forming pin (J)
and return spring (K) fit the assembly on the chain as shown in Fig 6. Fit the assembly to the
chain on the link to be broken as shown in Fig 3.
7. Wind in the T-handle to push out the pin, ensure the tool remains aligned. Only use the T-bar
provided to provide the torque required to push out the pin.
8. Once the pin is fully pushed through the chain can be separated (Fig.4)
