My wing vent window latch handles were very loose so I decided to clean them up and add some new washers and springs. My local Ace Hardware had everything needed.
I clean and repainted the vent window frame and added some neoprene washers (two outside and one inside) between the frame and glass to pull the handle closer to the frame. This made it latch a lot tighter which stopped any leaking around the vent window.
I replace the flat washer and nut with a new m12-1.25 nut and washer
I used my Dremel tool to polish the main bolt and inside the handles.
I replace the lock button spring and the handle retainer pins.
When reinstalling, I made sure to flip the bolts so that the handle retainer pin did not run in the worn side of the bolt slot.
