Marking the location of the control system balls in relation to the distribution plate
Install the balls in the housing. Use Volvo Genuine parts petroleum jelly (P/N 116 1151-40).
Identify where the balls are to be located. Press petroleum jelly into the relevant holes and position the balls (the petroleum jelly ensures that the balls stay in the housing). To mark the position of the balls in relation to the distribution plate, see Marking the location of the balls in relation to the distribution plate .
