    I need to replace my chain because it’s totally fecked:confused:
    How do you break the chain link to split the chain? Dremel or angle grinder followed by link breaking tool?
    And if a Dremel which tool? What does it look like? The discs I have all look a bit flimsy...

    Any help gratefully received :)

    Angle grinder to remove the rivets tops and a flat bladed screwdriver to lever the plate off

    Diamond Tip dremel, Grinder, Chain Breaker, I have even seen hacksaw used for despair measure (this apparently took the guy forever and he was cheap)...

    If you find the soft link you can file it flat in a couple of mins if you’ve no electric tools, then just push the link out, no need for chain splitter.

    ANGLE GRINDER??? Wtf?? Hell no, don’t want any sparks flying around and destroying my paint... use a chainbreaker. Such as:

    Thanks everyone for your help:)

    I’m going to try the diamond dremel attachment (as I have one) and if that fails the angle grinder:)

    I’m getting the chain breaker set to
    A) get the old link out
    B) rivet the new link pillar closed
    Anything I’m missing???

    Yes get a good set and do both jobs easily. Check your chain and you usually find a link that looks different. I/e it will have two indents in the link and that's the one to remove. Dremel maybe angle grinder asking for disaster.

    Even a cheap chain breaker will do the job without any grinding , if you find the soft link as Shaun mentioned, I done it recently on my O'ring 530 chain , on a 98 sprint , bought chain and breaker for £40 odd , from China ! Temporary chain as I'm mucking about with drive ratio !!

    I just used a metal file to file the rivets down then the tool pictured above to push them out. Didn’t take long

    After a couple of false starts managed to grind off the pillar head with the dremmel looking tool, I found taking it very slowly and gently the black cutting disc did the job

    And the chain breaker was indispensable not pretty result but chain broken and ready for replacement

    good job...first time is always daunting...

    but that goes the same for all the maintenance work...like changing your oil.

    After you done it once, next time will be a walk in the park.

    I tend to find the first time I do a job I am extra careful so it turns out OK, the second time I get over confident and that's when I have a disaster.

    Many thanks for everyone’s input, new chain now fitted, to finish I found flaring the pillars out after fitting the closing plate took a huge amount of force to get the shouldered domed pin on the breaker/ riveter tool thereby securing the plate. I ended up using a torque wrench to get enough force on the tool!!
