CHASSIS ENGINE TESTS We have been using a Tecalemit filter on the Unit Test Beds for something like six months. As you know engines are first run on the De Laval Separator before going to the Unit Test Beds, and whilst the engine is on the unit beds the Tecalemit filter is in the oil circulation. These filters are changed frequently, depending on the number of engines we are testing. LA{L. A. Archer} | ||
