Removing dual clutch
Prerequisites:
• Gearbox removed and secured to engine and gearbox support
⇒ page 76
.
• Mechatronic unit for dual clutch gearbox -J743- built into gear‐
box.
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.
♦ 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! It is not
possible to check the fill level of the hydraulic fluid section
of the mechatronic unit for dual clutch gearbox -J743- .
♦ 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.
♦ The breather cap -arrow A- on the mechatronic unit is de‐
stroyed during removal and must be renewed.
– Pull off both breather caps -arrow A- and -arrow B-.
Note
As an alternative to the engine bung set -VAS 6122- the sealing
cap -02M 409 120- can be used to seal the gearbox. The mecha‐
tronic unit can be sealed using sealing cap -0AM 325 120 A- as
an alternative. Order sealing plugs via the ⇒ Electronic 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.
