DID Chain / Chain Tool rivetting

Howdy All,
I am about to install a new chain on my bike and I believe I've purchased the parts I need.
I have a DID KM500 breaker/rivetter and a DID x-ring type OEM chain.

The chain requires rivetting and as this is the first time I've done this I thought I'd better ask for advice. There were no instructions sent with the tool so I'm most concerned about making a mistake here.

Can someone offer me some advice on this?

From what I've read elswhere on the internet and from looking at the chain and tool, I need to get the chain in place on the bike, grease and install the o-rings on the connecting link, put the plate on and then put the chain rivetting tool over the link and tighten until the pin end is 'splayed' by 0.4mm over it's original size. Repeat for second pin...

The DID tool has a flat end and a pin end and I guess the pin end is for breaking a chain and the flat end is for the rivetting?

Thanks for any advice and apologies for the disjointed email.
NB, I am 'comfortable' with removing the old chain and changing the front and rear sprockets...

Sounds like you got it about right. Rivit away.....

If you are unsure about the rivet tool, a grinder and a hammer does the job just as well. It doesn't take much to knurl the end of the new pin.

Make sure the back end of the rivet is properly supported by the tool (that means something solid on the far side) to push the rivet against. Otherwise when you go to peen the rivets you'll push it partway through and squish the o-rings.

So there should be an attachment that goes on the far side to hold the rivet and one on the peen side to peen it out. Just squish the rivet and you're good to go.

+1

I, too, would like to warn you about the dangers of squishing your peen, especially against an o-ring. Be safe out there!

Thanks all for your input.
Removing the old chain and installing the new chain went a lot more smoothly than I thought it would. The DID tool was excellent.
I rather surprised myself with my mechanical skills!
