      Information 

      There are different types of grease for the splines on the transfer gear.

      These must not be mixed, so it is absolutely essential to clean any remaining grease off completely.

    2. 1.2 Grease the splines of the drive shaft of the transfer gear and splines of the transmission output shaft.
    3. 1.3 Slide the transfer gear fully onto the transmission and at the same time, guide the splines of the drive shaft/transfer gear and output shaft/transmission together so that they are centred. If the splines are positioned correctly, the transfer gear will slide as far as it can go against the transmission.
