TM 9-2990-206-34&P CHAPTER 4 TEST AND PRESERVATION 4-1. TEST. Since turbosupercharger performance de- pends on engine performance, the turbo- supercharger cannot be tested unless it is installed on an engine. Therefore, testing a turbosupercharger not mounted on an engine will consist only of check- ing the turbine wheel for free rotation and making certain that turbine wheel radial clearance and end play does not exceed dimensions given on page 2-4. If the turbosupercharger passes these tests, it will perform satisfactorily when installed on an engine. CAUTION Turbosuperchargers must be lubricated before installation on an engine. Fill the center housing through the oil inlet port with engine oil (OE/HDO 30) before installing the oil inlet hose. a. Short Term Storage. (1) Fill turbosupercharger center housing with Preservative General Purpose Lubrication Oil (VV-L-8OO). Apply a light coat of the same oil to the exter- ior surface. Drain excess oil. (2) Wrap turbosupercharger with Waterproof, Greaseproof Barrier Mater- ial (MIL-B-121, Type II, Grade A, Class 2).
