The orientation of the thumbturn suddenly changed. MIWA U9.LDSP Repair

"Inspection and repair of malfunctioning keys"

It was the content that there are times when the key doesn't turn and sometimes it doesn't come off.If it was just this content, it would be improved by cleaning the cylinder, but when I actually heard it, it was a different symptom.

First of all, it was said that the orientation (position) of locking and unlocking the thumbturn suddenly changed.There was also content that the key could not be pulled out. I've been living in an apartment for about 10 years, but I can't imagine that the direction of the thumbturn would suddenly change.

Since it is an LDSP, I thought that the set screw was not installed properly when the front was removed.However, I removed the front and checked it, and it seems that there is no set screw defect.

When I disassembled and reassembled the thumbturn, there were times when the spindle could not reach the main body cam, so I adjusted it so that it could reach it.The tip of the spindle is not particularly worn, but I tightened it half a turn (about 1.5 mm) with the MIWA logo facing up.This MIWA logo position is the normal position.
