how to tighten chain on magnum 425
That's correct, don't hit anything with a hammer.[img]i/expressions/face-icon-small-confused.gif[/img]
Like I stated earlier, keep trying, once you get those eccentric bolts loosened and the punch inserted you may need to give it a sharp/hard push to get the "hub" to spin inside the "eccentric clamp". That was my problem when I tried the first few times, I wasn't breaking the "hub" loose from the clamps around it. You'll notice when the hub spins, it's like a lightbulb going off[img]i/expressions/face-icon-small-happy.gif[/img]...ahh now the chain is tighter. It was bear for me as well, insert the punch and rock the bike back and forth pretty hard, it'll break loose. There's quite a bit of play to adjust the chain so I don't think you need a new chain, just have to get the hub to break loose from the eccentric "clamp". Then it should go.
