I bet the problem was with the rejoining method. Most chains requir
careful assembly to ensure the pin is correctly reinstalled. If th
chain tool's drive pin is just slightly larger than the chain pin
removal will swage the hole in the side plate a few thiousandth'
larger, resulting in a poor fit.

A worn chain tool will also do this as the drive pin becomes slightl
"mushroomed" with use.

Still one more problem is incorrect setting. In old days, one jsu
needed to work the stiff link out with lateral pressure and flexing.
Not so today as the stiffness may result in the pin pulling out th
wrong way. Most modern chain tools have an additional "fence" to se
the chain clearance. See the complete instructions.

If you use one of the quick links, the chain tool use becomes les
critical. Most quick links are adequately strong but I have had on
come apart in use. I found the parts and was able to reassemble
