Mercedes double clutch transmission oil change steps

2018 - mercedes-benz double clutch transmission oil change step 10 - Dual clutch transmission is mainly assembled on A level (11 176). , class B ( 246). And the GLA ( 156). With a class B (below models, 246). Model as an example, this paper introduces the double clutch transmission oil change steps. 1, preparation before operation was carried out on the transmission operation, to ensure the absolute clean. Before open the hydraulic circuit, it is necessary to thoroughly clean the area around the separation point. During repair, be sure to wear is lined with a rubber oil, no hands to cover, to prevent small dirt particles from entering the hydraulic components lead to transmission failure. Transmission parts should be stored in a clean environment, proposed to parts covered or store it in a clean plastic box cover. Make the engine warming-up to the coolant temperature, at least to 80 ℃, and then close the ignition switch, will air filter shell removed along with the upstream of the engine inlet. 2, remove the transmission oil filter, and then remove the transmission oil filter cartridge. Loosen the upper portion of the oil sump bolts and lift vehicles and remove the plaque at the bottom of the engine. Remove the transmission oil drain bolt and loosen the lower part of the oil pan bolt after emission transmission oil, remove the oil sump. 3, clean the oil pan and install a new gasket, 8 nm torque tighten, then according to the oil drain bolt according to 30 nm torque tighten. Before starting the engine to join about 4 l transmission oil. 4, check the oil level before the engine warming-up under neutral idle speed. Need to manipulate the parking brake, it is necessary to let the engine idle speed running at least 2 min, to keep the engine speed running at more than 2000 r/min, diagnostic computer will show a box, need to keep engine speed within the box 3 s, when the engine torque intervention and engine speed to idle speed, not to operate the accelerator pedal and click 'continue' button to the next step. Measure the oil level to keep the engine at P idle running, until the transmission oil temperature of 40 ℃ ( Corresponding to the oil dipstick scale 3) Or 70 ℃ ( Corresponding to the oil dipstick scale 4) Measure the oil level, oil level during the inspection, the dashboard must have a 'F' character twinkle 5, check the transmission oil level need to be repeated 3 times, add or take out after the transmission oil, must be in line with the above steps again check transmission oil level. Finally the related parts and the disassembly parts to clean refitted.
