This method applies to the same wiper as the GLK300. Since last year, wipers have always jumped when wiping water. Using a strict version of toothpaste to remove the oil film and buying a polishing tool specially designed to repair rubber strips to polish it, the results are not ideal. Therefore, before the summer of this year, it was decided to replace the wiper strips. To replace the rubber strip, we should try to minimize the damage to the original wiper blade, so we searched the Internet for various homework and videos to learn how to replace the rubber strip. We bought the corresponding model of rubber strip on Pinxishang and started construction.
The rubber strip of GLK’s wiper is separated from the upper and lower rubber strips. The rubber strip in contact with the glass surface is embedded between two steel sheets in the wiper housing. In the wiper housing, there is a metal fixing tooth at one end pressing the rubber strip. Therefore, one end of the rubber strip is fixed in the wiper housing and the other end is movable.
Construction tools: a small linear screwdriver, a wallpaper knife
Step 1: Find the fixed end
Step 2: Use the thumb, index finger and middle finger of both hands to pinch the housing and the rubber strip at the fixed end of the wiper (it also works from the other end), and force the rubber strip from between the two steel sheets. During the pulling process, use even force to avoid deforming the steel sheet. Pay attention to pulling out the rubber strip sandwiched in the steel sheet from the beginning. Due to the aging of the rubber strip, the rubber strip may be torn, and the part inside the steel sheet cannot be successfully pulled out. A one-word screwdriver or other tool can be used to assist in removing the rubber strip.
Step 3: After the adhesive strip is pulled out, observe the inside of the steel sheet at the fixed end, find the fixing teeth, and use a one-line screwdriver to push the fixing teeth upwards to reduce the force of the fixing teeth biting the back of the adhesive strip. You must neither fail to bite nor bite too tightly, which will affect the smooth installation of the new adhesive strip
Part 4: Determine the length of the new adhesive strip and cut off the excess part with a wallpaper knife.
Step 5: Thread the back of the adhesive strip between the two steel plates from the fixed end of the wiper, and drag it to the other end little by little until it is all dragged in. The resistance of the fixed teeth can be felt during the dragging process. For example, the adhesive strip cannot pass through the fixed teeth or if the resistance is too large, the biting gap between the fixed teeth is too small. On the contrary, the biting gap is too large and cannot play a fixing role. Use a linear screwdriver to properly adjust the bite clearance of the fixed teeth to stabilize the adhesive strip and allow the adhesive strip to pass smoothly. Even if there is no bite force, it will not affect the use.
At this point, the dogma has been replaced and the truck can be loaded.
I would like to thank my card friend hpenny for his pictures and homework. Link: www.xcar.com.cn/bbs/viewthread.php? tid=18458439
