(51) FIG. 7 shows a schematic illustration of an example of a housing 30 of a vehicle, whereby the housing 30 can comprise an oil filter arrangement housing 32 with a recess 31 and the housing is shown as an example of a motor housing.

(52) In other words, the oil filter arrangement is configured to be housed in a hole of a motor housing. The hole in the motor housing can be made at the side where subsequently the transmission housing is supposed to be attached. So, the oil filter arrangement is radially guided in the hole by proper clearance between oil filter arrangement and hole at the area around O-rings and radial grooves. Additionally, the filter is guided at the bottom of the hole in motor housing via a recess made in the motor housing.
