I've had this chain laying around for a few weeks now because I don't have the special tool for putting the rivet on. I've heard you can use a hammer/center punch to ping down the rivet. Is this safe? I just don't want the new chain to come flying off because I didn't use the right tool. However, the chain tool is expensive and you pretty much have to order it online to get the best price. thanks for any help.
the new chain comes with spacers for the master link to make sure it goes back together right. i guess you slide them between the plates on the link, then back out when it's riveted.
I know how to remove the old chain. My big q is how to get the NEW rivet back on. I got some punches that are almost big enough, but how do I know when the rivet is secure? I've heard you can just tap it down with a ball peen and a sledge on the backside to hold it.
