1: Snapping the pegs off the tool!torqueless":2suwgaxa said:The worst-case scenario hasn't even been mentioned yet...Good luck!
2: Pegs slipping out the recess's!
3: Tool and block ruined making wheel buggered!
These can all be avoided if done correctly and that the tool is a mint fit into the block.
**Make sure the peg recess's are cleaned out before fitting the tool**
I'm reporting you lot for scare-mongering ;-)

If the pegs snap off the tool or the block recesses get damaged and rounded then, if the wheel is worth saving, it's time to scrap the block altogether. Get a punch/drift and undo the face plate using the 2 dimples in the plate (opposite thread to remove), pull the outer block and sprockets off the body, remove the small wire that acts as a pawl spring and remove the 2 pawls. This will leave 2 recesses opposite each other where the pawls sit. These recesses act as 'flats' that can be clamped tight in a vice, or, if you have one like me, a 36" stilson pipe wrench does the job.

Ouch! :x Exhibit B,
I don't think the design of this particular block was giving me much support. Doubtless there was a dedicated removal tool for it which I should have used instead of the generic 2-prong one pictured. IIRC I got it loose without going through the whole thing described by originalshinkicker. If you do have to go through that, the block is still salvageable/rebuildable BTW, if you think worthwhile.
Couple of things, it's a Suntour cassette so got the right tool. That previous shot differs from what I have as the centre piece and locking bit is recessed, so fingers crossed I don't have the same problems.

yeah I can see that would have worked on my freewheel, with it's slots standing proud of the lockring. Probably not on a-lonestare's though.

Confucius say: "Wise man when buying freewheel also buys dedicated removal tool, sparing himself much vexation"
Every time I've screwed a block to a hub I've wished I had one of those very thin spacer-ring things to put on first, but never have had one at hand. I think I had a couple from a bike shop years ago-god knows what happened to them. In these 'cassette' days I don't even know how to ask for such a thing.

I can see exactly why your pegs jumped out the recess's of the freewheel! The pegs are too deep
on the tool and should have been ground down slightly so the pegs and the steel face sat right
up against the block, This slight mod' would have stopped the tool from rocking about whilst trying to unscrew the block.

Thanks.. yeah I see what you mean. My lame excuse is that I was probably saving those prongs for the next freewheel removal, during which I would be glad I hadn't ground them down. False economy.. :roll: (makes mental note to check how tool mates with other freewheel, and grind down tool if necessary)
