Calculation of gear ratios

Example:

 

7th gear

Final drive

Drive gear

ZG1 = 49

ZA1 = 17

Driven gear

ZG2 = 32

ZA2 = 71

i = Z2 : Z1 (Z1 = number of teeth on drive gear, Z2 = number of

teeth on driven gear)
iG = Gear ratio = ZG2: ZG1= 32 : 49 = 0.653
iA = Final drive ratio = ZA2 : ZA1 = 71 : 17 = 4.176
Overall ratio = total ratio = iG x iA = 0.653 x 4.176 = 2.730

Caution

Risk of damage to gearbox.

♦ Only the gearbox oil for the 7-speed dual clutch gearbox

0CG, which is available through the replacement parts

system, must be used ⇒  Electronic parts catalogue “ET‐

KA” .

♦ Other oils will lead to malfunctions or failure of the gear‐

box.

♦ 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 the hydraulic line between the valve block of the me‐

chatronic unit for dual clutch gearbox -J743- and the con‐

nection for the disengagement clutch of the electric drive

motor -V141- is being removed, seal all connections with

suitable sealing plugs. After reinstallation of the hydraulic

line, hydraulic fluid must be replenished through the

breather connection of the mechatronic unit , if necessary.

For allocation of the sealing plugs, hydraulic fluid and fill‐

ing equipment refer to ⇒  Electronic parts catalogue .

♦ 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.
