Spent 3~4 hours adjusting my rear "Derailleur" but whatever I did, couldn't get the gear change at both ends at once if I manged to get a smooth change at low gears couldn't get it onto the highest cog if I got a smooth change at the high gears then I couldn't get it to change to the lowest cog , was in a quandry then thought, I know I will look on Sheldon's site as I am obviously doing something wrong. There staring at me is "before adjusting anything check the rear "Derailleur" isn't bent" I was adjusting it in the correct way but the rear derailleur had been dinged and was curved rather than straight compared to the "Derailleur" on my road bike . So tried to swap the "Derailleur" on my road bike over to the ATB got both "Derailleurs" loose and 'de-cabled' only too find I can't locate my chain spliter (chain tool) so will have to make a trip to the LBS tomorow and get a new one will re-assemble and let you know how I got on.

You can take a deraileur off a chain without splitting it by removing the two little bolts which are the axles for the jockey wheels (the cage will come apart). While it's apart grease the bushes - the little metal sleeves the bolts go through on which the wheels actually turn.
Also, check that your inner cable slides freely in the outer - sticky cables are a common source of bad shifting.

Hadn't wanted to do that, as I had visions of little springs and washers flyimg everywhere as it was the operation was a fairly pain free swapped the "Derailleurs" last night in the rain etc. (wasn't 'allowed' to do it inside as SWMBO would complain) but today I shall cable-up and adjust for best working. -- yours S

But don't lose any of the small parts when it all goes "ping" - especially whilst reassembling, and then have to bore a out a 5mm hole in a bit of 7mm steel bar to replace the lost bit. Of course, I'd never be that careless myself......

Must admit I thought there would be lots of springs and little unidentifiable bits flying everywhere but this didn't happen (to me) maybe because it was a cheap "Derailleur" but there was a minimum of loose parts.

No there aren't too many loose parts in most derailleurs, but still don't take your bike apart on the garden lawn :-)

Which again leads me to ponder why no other manufacturer has yet copied Sun Tour's "Quick Cage" feature which allowed the chain to be removed without having to do /anything/ with the derailleur...

They were nice weren't they?
It may of been patented, also it made the cage less resistant to bending and twisting.
