Removing a lefthand crankset?
When removing the left crankset, after removing the dustcap, Which way do you turn the nut? clockwise or anti-clockwise?
I have done this many times before but can't remember. I figure as it is on the left, then it should be clockwise. But I can't shift mine.
I'm sure the lockring is clockwise.
Any help appreciated.

Crank removal
I've done it now thanks. The drive side nut is anticlockwise and the cup and lockring are clockwise. I have another problem now, I can't get a 129mm sealed bottom bracket. I have to have either a 127 or a 131. It is a 25 year old bike. Problem with old parts.

2mm is a pretty small difference. Should be insignificant. You have to decide if your chainline would be best a hair outwards or a hair inwards of where it has been.

Is 129mm the length of the original cup-and-cone spindle? Often those older spindles were asymetrical (the drive-side stuck out a bit further).
If this is the case, a slightly longer--but symmetrical--cartridge bottom bracket may be what you want (the drive-side would be the same length, but the non-drive side would stick out a bit further than originally).
I would compare how far the drive-side spindle sticks out past the cup on both the original and a new bottom bracket--and match them up.

If the above is not the case, sorry for the unnecessary info....

The axle is the same length on both sides, which is unusual. I have Sheldon Browns site linked to my own site thanks. It is a great site and gives lots of tips. But I was unable to loosen the cones on my old Raleigh. didn't have the correct tools so tried to use a screwdriver to knock loosen them, but no use.
It always looks easier in the manuals :-)
Anyway. I have fixed the bottom bracket on my Claud Butler. Both bikes are 25 years old so may be a bit different to the new ones. The nut on the drives side unwinds to the left, but the cone and lock ring to the right.
