TM 5-4320-306-10 1-9. LOCATION AND DESCRIPTION OF EXTERNAL COMPONENTS (Continued) LIFTING BAIL (15). The lifting bail provides a secure point of attachment for lifting the centrifugal pump unit. The bail is secured to the skid frame at the centrifugal pump unit center of gravity. EXHAUST SYSTEM (16). The exhaust system components vent engine exhaust gases from the exhaust side of the turbocharger. The components include a spark arrestor, muffler, and the exhaust pipes between the muffler and turbocharger. FABRIC COVER (17). The fabric cover fits over the centrifugal pump unit. It protects the components from environmental conditions when the unit is not in operation. The cover is made of a flame-resistant, vinyl-coated nylon material with rubber tiedowns that hold it in place. 1-10.
