September 4, 2024

Materials:
Stainless steel drill iron screws M4.2*25 *1 piece

Tools:
wrench
hammer
towel
impact driver
Iron drill bit 4.0mm
Iron drill bit 3.2mm

Note:
Collect iron filings to prevent wind blowing away and short-circuiting various joints
The upper hole is slightly larger and can hold the nut
The lower hole is slightly smaller and is tightly stressed with the screws
The pulling force comes from the upper hole nut and the lower hole thread

Difficulties:
simple

Loosen the nuts, lay 2 layers of towel on the wiper arm,
While pulling, use a hammer to hit the side of the wiper arm,
You can spray some wd40

Use 1 screw, stainless steel drill iron dovetail,
Thread 4.2 mm, length 25mm, nut 10.8 mm
M4.2*25, 304 or 410 stainless steel

The upper hole is slightly larger and cannot be tightly combined with the threads

The lower hole is slightly smaller and must be closely integrated with the thread

Tighten the screws, the pulling force comes from the engagement of the nut in the upper hole and the lower hole

If you are afraid of rust, apply anti-rust paint on the inner wall of the upper hole and the nut

Above one finger width

If there are no screw repair conditions, you can use this adjustment screw.
This screw is used to adjust the height of the cover after it is closed,
Raise the cover and leave an extra 3mm gap for the wiper arm,
This problem can also be solved.

It is recommended to adjust both sides of the cover at the same time, not too high,
Otherwise, there will be a large gap between the fender gap and the wind tunnel.
It will increase noise and wind resistance.
