• It's not just you, I have had so many problems with freewheels, most of them probably bought on by myself.
    Firstly is the freewheel worth keeping?
    Because the tool to remove it is not cheap.
    The park tool _FR 2 has the wrong size prongs you will need

    Use the tool to release the complete freewheel from the hub. It locks into position using the hub spindle and tracknuts or quick release spindle and lever depending on your hub.
    I have just bought one for myself which you are welcome to borrow.
    If the freewheel runs smoothly I would leave the pinholes alone as if you use them to undo the nut all the ball bearings will fall out and the freewheel will separate into two parts.
    If you are going to take the freewheel apart
    You will need a wrench or vice to then unscrew the centre part of the freewheel from the hub.
    It will be very tight.
    Getting it back together is very fiderly and you will probably wish you hadn't bothered.

  • Ha! Sounds like I’ll not bother, I lose my patience even with loose bearing bb maintenance. Will look for a new (old) block instead, once I collect the wheels and see what’s needed.
    Then I might be tempted to have a go at it, just for larks :)
