By some strange coincidence I’ve been leafing through a copy of mbr from October 2012.
Their five minute fix covers superstar nano/ kona wah wah service.
They say that rebuild kits are available for £15 from superstar.
They use a 6mm Allen key along with 8 and 9mm sockets.
Once you get the axle and outboard cartridge bearings out of the pedal, you’ll need to stick a screwdriver in to tap out the inner bushing with a hammer.
Hope that makes sense.

I’ve got a magnesium pair that unclip from the cranks. The threads on the pedal axles are super tough.
