not got a 36 or 37t one have yer??

Another way to make sure you got the eccentric in the right area is to see which way you have to turn the adjustment spanner to tighten the chain. Quite simply, if you have to pull up on the spanner to tighten the chain, the eccentric is in the right area, i.e. below the hub.

This is where it should be.

greta pic - so should it be at 5 oc as andy says or 9 as the pic shows?

It should be in the 4 to 5 area in the pic, probably why that section is shaded.

Or as Geoff Baines said to me when I first got my 916 " make sure it is between 6 O'clock and 9 O'clock when viewed from the wheel side.
