4-18. BLEED AIR CONNECTOR.  The bleed air connector (1, figure 4-11) is Installed in the top of the inlet hous- ing (2) and connected to the air filter (5) by the bleed air line (3). Bleed air  at  approximately  25  psi (172.38 kPa) goes from the inlet housing to the air filter where it is used to remove foreign matter. Foreign matter   is removed from the air in the air filter tube  assemblies. a. Inspection. (1) Loosen turnlock fasteners and remove  engine  housing  access  cover. (2) Ensure that bleed air connec- tor (1) is secure in compressor inlet housing  (2). Torque to 135-150 inch pounds  (15.3-17.0  Nm). (3)  Ensure  that  bleed  air  line (3) is securely attached. (4) Install engine housing access cover and secure with turnlock fasteners. b. Removal. WARNING To  prevent  injury,  ensure  that battery is disconnected  before performing  maintenance. (1) Disconnect battery cable plug connector. (2) Loosen turnlock fasteners and remove  engine  housing  access  cover. (3)  Unscrew  bleed  air  line  (3) from bleed air connector (1).

Installation. (1)  Place  new  preformed  packing (4) on bleed air connector (1). (2)  Install  bleed  air  connector in  compressor  inlet  housing  (2)  and torque 135-150 inch pounds (15.3-17.0 Nm). (3) Connect bleed air line (3) to bleed air connector (l). (4) Install engine housing access cover and secure with turnlock fasteners. (5)  Connect  battery  cable  plug connector. 4-19. BLEED  AIR  LINE.  The  bleed  air line  (3,  figure 4-11)  is  connected between the bleed air connector (1) and the  air  filter  (5). It  provides  a passage for bleed air at approximately 25 psi (172.38 kPa) from the compressor inlet housing (2) to the air filter. a. Inspection. (1) Loosen turnlock fasteners and remove  engine  housing  access  cover. (2). Make sure that connectors are tight. Tighten if loose. (3)   Check   hose   for   abrasions, kinks, or twists. Replace if damaged. (4) Install engine housing access cover and secure with turnlock fasteners. 4-59
