WEST917-TX type, the cylinder suddenly became idle and could no longer be locked.

"Cylinder malfunction, inspection and repair"

This morning, the key suddenly turned in the wrong direction and the door could no longer be locked. This phenomenon occurs when the pull-leg screw loosens on the LSP type, but the cylinder collar did not turn, so this time I used the TX type.However, there was no loosening of the pull-leg screws.

I decided to take it apart and examine it.This type requires the handle and long seat escutcheon to be removed.It takes quite a bit of time.One of the front screws was also crushed and damaged.

When I took it apart and inspected it, I found that the tailpiece had come off.And one screw is missing.There's no way something like this could go wrong.It must have been a worker's mistake.This is the first time such a case has occurred.It's hard to believe.It must have fallen in the door, but if the tailpiece had fallen, it would have been a big deal.

I don't have 2mm junk screws to repair. Since it would not be complete with just one screw, I fixed it with a thinner screw using instant adhesive.

Furthermore, the tailpiece was attached with something that did not match the door thickness.New products usually come with two types of tailpieces.When I used a long one, it probably got stiff due to interference with the thumbturn.Furthermore, the screw torque that was installed may not have been sufficient.So after a long time the screws were missing.I think that the tailpiece was easily worked with a short one.

As an emergency measure, I adjusted the pull-leg by tightening it to a considerable amount of torque to distort the door.This would have allowed the tailpiece to be fixed into the spindle by about 1mm.With normal torque, spin will inevitably occur.This is also likely to have loosened over time due to aging.

In any case, this is an event that occurred during the appropriate work of the worker who replaced it.
