TOSTEM MIWA PA-01 Latch malfunction inspection and repair

"The movement of the latch has become strange"

The latch of TOSTEM MIWA PA-01 is malfunctioning. If it is just aging deterioration, it will be completed by spray cleaning, but this time it was different.

There is no defect such as breakage in the removed latch parts.
There was a gaping hole where the latch part of the lock case would fit, but the spring was stuck in a strange place. Assembly is possible in this state, but the spring does not work.

Carefully pull it out while turning the spring with fine needle nose pliers. Reassemble to the regular center position and you are done.

After hearing, it seems that the handlebar set was replaced about 11 years ago, but it seems that the assembly by the contractor at that time was defective and the spring had fallen off.It seems that the movement was strange, but it seems that it was used as it was.
