I removed the cog set by using two chain whips to unscrew the first cog which serves as the lock ring. After all of the cogs fell off, the freewheel remains on the hub, How do I get that freewheel off my hub? It will not turn using the appropriate free wheel tool and my largest 1/2 drive socket wrench.

I have just replaced my chain on my Marin hawk hill and the chain is slipping, I’ve placed the chain alongside the old one and made it the same size and upto now I’ve removed about 8 links using the propper tool, the chain feels ok when I’m in low gear ” biggest cog on the rear” but when I’m putting strain on the peddle and using the smallest cog’s “7th, 8th and 9th gears” it’s slipping like mad, do I need to take more links off?
Thank’s to everyone, I’ve been looking up more info on the web and also taken on board what you’ve all said, I’ve set up the gears and got the correct lenght of chain and it’s still poppin off the small cogs so the only thing to do now is replace the cassette. Can anyone tell me what I’ll need ie, tools and what sort of cassette and how to get the ****** off.. The bike is a 9 speed Marin Hawk hill???
