Chain Trouble...
I had an O- ring chain put on about a month ago from a local dealer and i wanted to take it off and clean all the dirt and let it sit in mineral spirits for a while to clean it all up. so i first took of the little clip thing and i got stuck from there, usually another piece comes right off and then the o rings then the rest pulls out from the back, done. except where the second piece cant come off because the pins are like the others, bent over so they wont come off. is this like a different master link or something?? i think its a renthal if that helps.

Re: Chain Trouble...
did you put a spacer on when you got the o-ring chain? they're wider and it sounds like it might be rubbing a little, which would cause something like what you're describing.

Re: Chain Trouble...
Racey, it is just a slight press fit. Take a #1 flatblade screw driver and pry it off. Fit the driver under the end of the side plate and use the next link as the fulcrum. Go back and forth end to end and it will come right off.
To reassemble, just take an 8mm boxend wrench, place it over the pin and with a vice grip press it back on. I made a special tool for this...I took said vice grip and drilled a hole slightly larger than the master link pins in one jaw. Presses the plate back on real easy.
Do NOT file the pin holes in the side plate to slide onto the link. You will be defeating the purpose of the press link.
I hope this was 1/2 way understandable. TW

Do NOT clean your O-ring chain in mineral spirits...not good for the orings.

Re: Chain Trouble...
FFR is correct, its a press fit side plate.

To clean your chain use Kerosene as it won't damage the o-rings or cut the grease. Also its not a good idea to let it soak, but to use a stiff paint brush or toliet scrub brush and dip it in kerosene and then scrub your chain or use a rag dipped in kerosene.
