Extend operating bolts until push pin is inside large outer bolt. Place chain in Chain Breaker body and clamp large outer bolt over link pin to be removed, push chain into body creating a bend in the chain where the pin is to be removed. (grinding of link pin head (Burrs) is not necessary. Steady chainbreaker body with a Terra-x tyre lever or a 17 mm spanner etc.. Push out link pin turning inner bolt, this will be hardest at the start. Keep going until link pin drops out the rear of the chainbreaker body.

Insert 10mm grub screw (supplied) into rear of chainbreaker body. Assemble link and loosely fit outer plate. Place chain in chainbreaker body and use large bolt (make sure push pin is retracted or removed altogether ) to clamp over link pin on one side of link. Turn in small grub screw in rear of chainbreaker body until the ball bearing touches the back of the link pin, this will prevent the link pin being pushed out the rear plate when pressure is applied to the front plate. Tighten large bolt to squeeze on outer plate, alternate between the two link pins until the clip groove can be seen. Fit spring clip

The chainbreaker now comes with a ball bearing in the supplied grub screw, this part is used to flare a rivet link.

The video shows how to do this, its a good idea to back off once or twice during flaring and just take up the slack created by tightening the large bolt, this will stop the movement of the chain that I had in the video.

We have always supplied chain pins for the occasional breakage that has happened by misalignment or some other reason. With the increase in use of the tool to flare links by forcing the pin into the hole in the rivet link, we developed the ball bearing part which works much better.
Replacement pins are available but will no longer be supplied free, and the ball bearing part is also available as an upgrade to anyone wanting to use their tool to rivet chains,

More info regarding rivet links:

Rivet links vary so much. The tool flares the pin end it doesn’t peen it over, you must use the rivet links with the hollow ends.

For example:  RK links are usually soft on the end and work very well, but some others can be very hard and its easy to either split the chain pin if you go too far, it only needs a slight flare.

Whichever chain and link you use it’s a case of gently does it.

You just have to make the decision if your happy with the flare you get on the pin.
