Archer}17/T21.12.37. We believe that engine cleansing is so important that we can, with advantage, use Tecalemit Filters during the DeLaval cleaning operation and road tests. In view of the fact that the filter is used on the suction side of the oil pump, we believe that special precautions should be taken to ensure that the oil pump and auxiliary pipe, etc. are perfectly clean.
