The RLV chain breaker has 2 bolts in it. One has the long pin on it for pushing the pin out of the chain the other has a cupped pin for pushing it back in. If you use the long pin to put it back together it’s going to break every time. You should also check for play or space side to side after you put it together. Sometimes you’ll find it’s to tight and you have to spread it a little to get proper spacing.
