Chrome locking gas cap

[TomsMB]

My gas cap no longer locks. The key turns the tumbler as required but whatever is supposed to lock the innards to the outside does not work. 
Has anyone disassembled the mechanism and if so, what is the trick?

Access to the inside tumbler and wafers of a Ymos locking cap will depend on the type you have. If it’s the single sided key model, it’s straightforward.  If it’s the later two sided key type, it may or may not be accessible.

Check the tech manual for an explanation of locks with access holes. If you have the two sided key cap, you may be out of luck if it lacks the small holes which release a clip holding things in place. For some reason some of the two sided caps have them but most do not.

Thanks for the response Ireppond. 

After I posted my question, I kept digging through the old postings and found the pages on the locking gas caps.  By following the instructions I was able to finish disassembly, clean it all up, regress the sliding part and reassemble. 

The exciting part is that it actually works for the first time in about 8 years.  I love it.  Small victories make Tom a happy man.
