Thanks guys, exactly what I was looking for.

Coolkid, if I wanted to take it to a bike shop, I never would have asked. I did do 5 minutes of resarch & my computer was just lagging. I came here & it worked straight away. Thanks for the coolkid advice.

You guys are great & thanks for the help! I have the grease & the Chain Whip/Lock ring spanner & just waiting for the cog & lr to arrive. -john
