Topic: SEAT LOCK

[fishman_Phil]

Hi all ... how does one remove the seat lock from it's housing? I see underneath the housing there is a small hole but not sure if it is there to assist or allow the removal of the lock assembly.

Back again ... went back out to the garage and had another go. Ah ha. By the cam there is a circlip that may need turning to the correct position to lever out with a small screwdriver. Also, lifting the brass plate out carefully, there were the springs and tumblers. If you had no key in the lock, they would also hinder it's removal.
What I wanted to do, was to put my lock mechanism into another excellent housing I had that still looked like new, but for which I had no key for.
All done now and can be installed onto my project bike.
If pulling one apart, best to get a sheet of white paper to lay things out on as removed and take note of the order the tumblers were in. If you do get them mixed up, they can be sorted by having the lock removed from the housing, insert the key, and then try different tumblers ensuring they sit down onto the key but remain floush with the top rounded edge of the lock itself.

It didn't work for me. I had a matching set but the seat lock was sunfaded, so I wanted to swap it for another one in top shape with no key. Did all the change, but it wouldn't work. Turned out that the holes in the housing and the keyhole seems to be made at the same time so they align perfectly. If you replace only the keyhole, the holes for tumblers may not align with the holes in the housing.

I ended up painting the housing.....  and learning a lesson.
