The wiper system plays a critical role in driving safety, especially in the harsh Russian winter or heavy rains. Cars. Skoda Octavia TourThe knot of trapezoids, which are famous for their endurance, is often subjected to wear due to aggressive reagents and ice accumulating under the hood.
When wipers begin to wheez, move in jerks or stop at all halfway, this is a direct signal of the need for diagnosis. Many car owners mistakenly change only rubber brushes or motor, not noticing that the problem lies in the mechanical part of the drive - trapezoid.
Ignoring the signs of malfunction can lead to burnout of the electric motor or breakage of brackets, which will significantly increase the cost of repair. In this article, we will discuss how to replace yourself. trapezoid wipers on Skoda Octavia TourWhat tools are needed and what hidden defects should be paid special attention to.
Diagnosis of malfunction and typical symptoms
Before you go to the store for spare parts, you need to make sure of the diagnosis. Symptoms of trapezoid malfunction are often disguised as motor or electronic problems. The most striking sign is the sound of the worker. wiper motorIt keeps buzzing, but the levers of the wipers are standing still or moving with great effort.
The second common symptom is uneven work. One lever can go through a full cycle, and the second stops in the middle or moves with a clear sagging. This indicates that the joints in trapezoid wipers have increased backlash or jammed bushings. Cars. Skoda Octavia Tour Often there is a situation when the switch on the "spiral" or "fast" mode, the mechanism gets stuck in the extreme position.
It is also worth checking the work of the janitors for cold. If after switching on they start, but after a couple of seconds stop, perhaps the thermal protection of the engine due to mechanical resistance is triggered. In this case, disassembling the unit It is mandatory, since constant work under load will quickly disable the electric motor.
- π Backlash check: Take the levers of the wipers and swing them up and down when the ignition is turned off. Luft more than 2-3 mm indicates wear of hinges.
- π Acoustic Control: Listen to the sound of the work. Screaming, crunch or hum without the movement of leashes is a sure sign of trapezoid jamming.
- βοΈ Visual inspection: Lift the rubber seal under the hood and inspect the trapezoid mounts for cracks or corrosion.
Selection of components: Original vs. analogues
Spare parts market for Skoda Octavia Tour It offers many options, and choosing the right component is the key to the durability of the repair. The original trapezoid from Skoda (VAG) is highly accurate and materials quality, but costs significantly more. Its service life with proper operation exceeds 10 years.
Analogues from manufacturers like Febi, Sachs or PTR They may be more attractive in price, but often have less quality sleeves that wear out faster. Cheap Chinese copies often have casting defects, which is why the shafts do not turn or quickly break the seats in the case.
Pay attention to the completeness. Sometimes it is better to buy separately. wiper motor and separately trapezoid, and sometimes sold a set in the collection. For Octavia Tour (body 1U2) it is important to choose the version that corresponds to the year of release, as the mounts may differ.
β οΈ Warning: Don't skimp on the sleeves. If you take an analog, make sure that brass or bronze sleeves come in the kit, not cheap plastic ones that break quickly and cause backlash.
When buying, be sure to check the VIN code of your car with the catalog number of the spare part. This will eliminate the error, as in different versions. Skoda Octavia Trapez can stand with different lengths of thrusts or the number of levers.
Toolkit and preparatory work
For quality repairs, you will need a standard set of tools, but there are nuances specific to the Skoda Octavia Tour. You definitely need end heads of 8, 10, 13 and 16 mm, as well as an extension cord and a cardannacle to access the lower nuts of the attachment.
Donβt forget about the flat screwdriver and a set of keys for removing plastic linings. If the thread is boiling, you will need penetrating lubricant (for example, WD-40) and a heater. Also prepare a container for draining water from the underhood space, as when removing the trapezoid you can damage the seals.
Before the start of work, it is necessary to de-energize the car, removing the negative terminal from the battery. This will protect you from accidental motor operation or short circuit when the chip is turned off.
βοΈ Preparing for replacement
Pay special attention to cleaning the area around plastic-shell. Mud and sand, caught in the mechanism during disassembly, can cause a new trapezoid to jam. Wash the area under the hood with water and wipe dry.
- π οΈ End heads: a mandatory set of 8 to 16 mm for removing mounts and levers.
- 𧴠Lubrication: a universal silicone lubricant for treating new bushings before installation.
- 𧽠Cleaning: rags, brush and water to remove dirt before work begins.
Step-by-step instructions for dismantling
We begin the process with the removal of plastic decorative linings under the windshield. They are attached to clips and nuts under plastic plugs. Carefully tuck the plugs with a flat screwdriver so as not to break the plastic, and unscrew the nuts of the mount.
Then the janitors' levers must be removed. They are placed on conical slats and can boil. Do not try to disrupt them by force, so as not to damage the shaft of the engine. Use the removable or gently sway the lever, pre-treating the connection with penetrating lubricant.
After removing the levers, unscrew the mounting bolts of the plastic casing and remove it. Now you see the self. trapezoid wipers and the motor. Disconnect the electric connector from the motor by pressing the lock.
Unscrew the trapezoid mount bolts to the body of the car. Usually there are three or four of them located around the perimeter of the node. Be careful not to drop bolts inside the body or into the ventilation holes.
What to do if the janitor's lever is not removed?
If the lever does not lend itself even after processing with lubrication, use a special remover. If it is not, you can carefully heat the landing site with a hairdryer or burner (without overheating the plastic), but it is best to use a remover so as not to damage the shaft of the motor.
Remove the old trapezoid, disconnecting it from the shaft of the motor. If you change both the motor and the trapezoid, then unscrew the engine from the body and remove the knot completely. If you change only the trapezoid, leave the motor in place, but carefully disconnect it from the trapezoid levers.
The main task during dismantling is to preserve the integrity of the shaft shaft of the motor and not damage the plastic elements of the body when removing linings.
Installation of a new trapezoid and nuances of assembly
Before installing a new trapezoid, lubricate all movable hinges and bushes with silicone lubrication. This will significantly extend the service life of the mechanism and ensure smooth running. Make sure all the levers move freely without jamming.
Set the trapezoid in place, combining the holes with the mounts in the body. Tighten the mount bolts with moderate effort so as not to tear the thread in aluminum or plastic body inserts. Connect the electrical connector to the motor before clicking.
Install plastic linings and secure them with nuts. Do not tighten the nuts to the end at once, first cash them all, then evenly tighten them. This will prevent plastic skewing and the appearance of creaks.
β οΈ Attention: Before the final tightening of all mounts, check the course of the wipers, turning on the ignition and briefly supplying power to the engine. Make sure that the trapezoid does not touch the body or linings.
Set the wiper levers on the ramparts. This is the most important stage, since the angle of deviation and the glass cleaning zone depend on the correct installation. The levers should fall into place with a characteristic click or effort.
After assembly, check the operation of wipers in all modes: slow, fast, intermittent and washing mode. Make sure they stop in the lower position and donβt touch each other or the racks.
Common mistakes and advice from professionals
One of the most common mistakes is the wrong installation of levers. If you put them in the wrong position, wipers will leave unmixed areas or hit a rubber sealer. Correct installation requires that the levers stand parallel to the racks when the state is off.
Ignoring the lubrication of the bushings also leads to rapid wear. Even a new trapezoid can jam after six months, if it used dry or poor-quality bushings. Always use a special one. silicone greaseNot lithole or graphite lubricant.
Another mistake is to try to save on the quality of the parts. Cheap analogues often have backlash in hinges already when installed. This leads to the fact that the janitors begin to βjumpβ on the glass, leaving divorces.
- π« Do not use silicone to lubricate the shaft of the motor, only for bushings.
- β Check the mechanism before installing plastic linings.
- π§ Always use the removable to remove the levers so as not to spoil the shaft.
If after replacement wipers work with noise, check if they touch the plastic casing or rubber seal. You may need to cut the seal or adjust the position of the levers.
It is also worth paying attention to the condition of the motor. If you removed the trapezoid, check the shaft of the motor for backlash. If the engine is old, it is better to replace it immediately, as the new trapezoid may not withstand the load from the worn engine.
- Very simple, I managed in an hour.
- Medium, it took time.
- Difficult to do, need specialist help
- I haven't tried it, I'm afraid I'll ruin it.
