Aandrijfas chassis en transmissie, controle oliehoeveelheid

1. Check the chassis leakage
& nbsp; & nbsp; & nbsp;Check the gearbox and other parts of the chassis to see if there is any leakage, and if it is found, it should be eliminated.
& nbsp; & nbsp; & nbsp;Check the damage of the brake pipeline and power steering system pipeline, and there must be no leakage of liquid or air. If the pipeline is leaked or damaged, it should be repaired or replaced.
& nbsp; & nbsp; & nbsp; & nbsp;Second, replace the transmission gear oil
& nbsp; & nbsp; & nbsp;Due to the improvement of manufacturing technology, the reliability of the transmission is relatively high, and it is generally not prone to failure and damage. During the inspection, the parts such as oil leakage, dust cover and seals should be inspected. If damage or sealing performance is found to be damaged, it should be repaired or replaced.
& nbsp; & nbsp; & nbsp; 1. Draai de afsluitschroef van het oliepeilinspectiegat los, controleer of het oliepeil het gespecificeerde oliepeil bereikt en controleer de schaal van de gatzijde O -15 mm. Als de hoeveelheid olie onvoldoende is, vul dan de versnellingsbakolie bij zodat het oliepeil de gespecificeerde schaal bereikt en controleer op olielekkage.
& nbsp; & nbsp; & nbsp;2. When changing the gear oil, start the vehicle first, run or drive a certain distance to make the transmission gear oil warm up. While the gear oil is still warm, unscrew the oil drain plug to drain the gear oil. When installing the oil drain plug, pay attention to that the oil drain plug of some models is magnetic. After removing the iron powder adsorbed on the screw plug, screw it firmly. Then add new gear oil that meets the requirements until the gear oil overflows from the oil level inspection hole, and install the inspection hole plug.
& nbsp; & nbsp; & nbsp;The gear oil of the transmission of the Jetta car does not need to be replaced during use, just check for leakage. If the transmission is found to be leaking, repair the leak and add gear oil.
& nbsp; & nbsp; & nbsp;3. Inspection and replacement of drive axle gear oil
& nbsp; & nbsp; 1. Draai de afsluitschroef van het oliepeilinspectiegat los en controleer of het oliepeil de schaal O -15 mm aan de zijkant van het oliepeilinspectiegat bereikt. Als de hoeveelheid olie onvoldoende is, vul dan de transmissieolie bij totdat de transmissieolie uit het inspectiegat in de kooi stroomt.
& nbsp; & nbsp;2. Change the gear oil, start the vehicle for a certain distance, and warm up the axle gear oil. While the gear oil is still warm, remove the oil drain plug to release the gear oil. After draining the gear oil, wipe the screw plug and screw it back firmly into the axle housing. Then unscrew the oil level inspection hole plug, add new gear oil until the gear oil overflows from the oil level inspection hole, and finally install the inspection hole screw plug.
& nbsp; & nbsp;4. Check and replenish the oil volume of power steering hydraulic oil, and replace the hydraulic oil if necessary
Reinig eerst de buitenkant van de olieopslagtank van de stuurbekrachtiging en controleer het oliepeil. Als de hoogte van het oliepeil lager is dan de onderste limietschaal, moet u dezelfde soort hydraulische stuurolie toevoegen tot de bovenste limietschaal (MAX). Controleer voor het toevoegen de pijpleiding op lekkage. Controleer bij het controleren of toevoegen van hydraulische stuurolie de vervuiling van de oliekwaliteit en vervang deze op tijd als blijkt dat deze is verslechterd of vervuild. Speciale aandacht moet tijdens het gebruik worden besteed om te voorkomen dat vuil of stof de olieopslagtank binnendringen.
& nbsp;The steps to replace the hydraulic oil in the power steering system are as follows:
& nbsp; & nbsp; 1. Zet het voorwiel in een rechte - rijstaat, hef de voorkant van de carrosserie op met een krik, zodat het voorwiel vrij kan draaien en ondersteun de vooras met een vaste beugel.
& nbsp; & nbsp;2. Remove the power steering inlet and outlet oil pipes on the power steering gear. The positions of the oil pipes are shown in Figure 1. Put the oil pipe joints and gaskets in a container with clean power steering hydraulic oil for cleaning; The oil tank cover allows the hydraulic oil to flow out naturally.
& nbsp;3. With the oil pipe removed, turn the steering wheel to the left and right extreme positions repeatedly to remove the old hydraulic oil in the power cylinder and connect it with an oil basin to prevent the hydraulic oil from splashing on other components.
& nbsp;4. After draining the hydraulic oil, the oil pipe should be reinstalled.
& nbsp;5. After filling the oil storage tank with new hydraulic oil, start the engine and run it at idle speed. At this time, the oil level will immediately decrease, so it is necessary to continuously add hydraulic oil. When the liquid level in the storage tank stabilizes, the hydraulic oil should be replenished to the upper limit (or & quot;MAX & quot;) of the storage tank.
6. After the engine speed is increased to medium speed, turn the steering wheel to the left and right several times to make the air in the hydraulic system flow back to the oil storage tank and then be discharged. Therefore, the exhaust operation should be carried out until the bubbles in the oil storage tank are completely Until it disappears, and add hydraulic oil to the upper limit of the dipstick at any time.
7. After finishing the exhaust operation, wipe off the oil stains, turn the steering wheel to the left and right several times, and check whether there is any oil leakage in each part. After placing the front wheel in the straight position, stop the engine rotation, withdraw the bracket, and lower the front wheel. Check again that the hydraulic oil volume has reached the upper limit of the reservoir.
