It doesn’t matter where you start. Just start.
Kim, you are very bad!
I managed to remove the cap witha small screwdriver. Now the problem is getting a 10mm ring spanner in the small gap between the pedal end and the nut inside. I don't possess a 10mm ring spanner...
MKS make lovely pedals which are impossible to service without an extensive workshop imo. We have used the Sylvan Touring pedals extensively but servicing requires a spanner the likes of which I just don't have and don't seem to be able to buy.I'll lurk and watch with interest.
Just unbolt the cage to give access to the axle locknut?
