Seal gearbox so that it is oil-tight.
Caution
Risk of damage to gearbox.
Before repairs, the breather of the mechatronic unit for dual
clutch gearbox -J743- (-arrow A-) and the gearbox breather
(-arrow B-) must be sealed so that no oil can escape.
♦ It is not possible to check the fill level of the hydraulic fluid
section of the mechatronic unit for dual clutch gearbox -
J743- . Before repairs, the breather of the mechatronic unit
for dual clutch gearbox -J743- must be sealed so that no
oil can escape.
♦ If any oil escapes from the hydraulic fluid section of the
mechatronic unit for dual clutch gearbox -J743- , the oil
must not be filled back into the mechatronic unit!
♦ If hydraulic fluid has escaped, it must be replenished
through the breather connection of the mechatronic unit ,
if necessary. For allocation of the sealing plugs, hydraulic
fluid and filling equipment refer to ⇒ Electronic parts cata‐
logue “ETKA” . If possible, replenish the hydraulic fluid
after the gearbox has been installed. After the hydraulic
fluid has been replenished, dispose of the remaining hy‐
draulic fluid and the sealing plugs.
♦ If oil escapes from the gearbox oil section, it can only be
rectified by changing the gearbox oil. It is not possible to
check the fill level.
♦ If the level of oil/fluid is too high or too low in either of the
parts, the function of the gearbox will be impaired.
– Pull off both breather caps -arrow A- and -arrow B-.
Note
♦
The breather cap -arrow A- on the mechatronic unit is de‐
stroyed during removal and must be renewed.
♦
As an alternative to the engine bung set -VAS 6122- the seal‐
ing cap -02M 409 120- can be used to seal the gearbox. The
mechatronic unit can be sealed using sealing cap -0AM 325
120 A- as an alternative. Order sealing plugs via the ⇒ Elec‐
tronic parts catalogue “ETKA” .
– Seal gearbox breather and breather of mechatronic unit for
dual clutch gearbox -J743- with clean sealing plugs so that no
oil can escape.
