The epiploon of the main transfer / transmission is established in a case of the main transfer, at the same time the pressurizing edge adjoins to a regulator mechanism fillet in the transmission.

If you need to replace only epiploons, the transmission and the main transfer should not be inclined at separation to avoid loss or mixing of oil.


Prevention

When replacing the main transfer or the transmission, it is necessary to check an axial gap and, if necessary, to adjust.

Do not start the engine and do not tow the car at the removed oil pallet or when in the transmission there is no oil.

The block of valves can be removed and installed without removing the transmission from the car.
