Shimano chain with preinstalled pin
I purchased a HG-93 chain at CRC, and got an OEM one. It did not come with a reinforced connecting pin, but had a "normal" pin already halfway inserted in the end link.
Am I supposed to just use this preinstalled pin? I will need to cut the length of the chain, so in theory I could cut away the link with the preinstalled pin, and use a reinforced connecting pin instead. The problem is that it is recommended to do this from the "inner plate"-side, not from the "outer plate"-side.
Could I use a chain tool to push the preinstalled pin away and use a reinforced connecting pin, or will this damage the plates?
Any suggestions? Anybody know what kind of pin this preinstalled is?
