NOTICE: Refer to Chapter 73-10 in the TEO-540-A1A Engine Maintenance Manual for
suggested routing and configuration arrangement diagrams for fuel hoses on this
engine. The fuel hose configuration diagram is for reference only. If specific fuel
hose routing information is in airframe documentation, follow the airframe
instruction. Fuel hoses must be examined during every visual inspection as per
the TEO-540-A1A Engine Maintenance Manual.
B. Make sure cushioned clamps securely attach fuel hoses (to dampen vibration during
flight). Do NOT use plastic tie straps in place of cushioned clamps.
WARNING DO NOT ROUTE FUEL HOSES CLOSE TO HEAT SOURCES. HEAT
C. Do not let fuel hoses touch the engine or airframe baffle hardware. There must be a
minimum clearance of 3/16 in. (4.76 mm) between a fuel hose and any engine or airframe
surface.
Step 10. Connect the Oil Hoses
CAUTION
MAKE SURE THERE ARE NO SHARP BENDS OR KINKS IN THE OIL
HOSE ROUTING TO PREVENT INTERRUPTIONS TO OIL FLOW. DO NOT
ROUTE OIL HOSES CLOSE TO HEAT SOURCES.
1. Connect the oil hose from the oil sump to the wastegate.
2. Connect the oil hoses from the airframe-supplied oil cooler.
3. Clean each oil hose section and install it in the respective areas. Make sure the oil hose
routing is smooth, without sharp bends, kinks or helical twists.
4. When making the following oil hose connections:
A. Align the oil hose with the fitting for best orientation (without kinks or sharp bends).
B. Torque the fitting to the torque value in the latest revision of the Service Table of Limits -
SSP-1776.
Step 11. Attach Ground Straps
NOTICE: Ground straps are necessary to make sure that the EECS operates correctly, and that the
sensors and actuators have the necessary ground for correct operation. The ground
straps are a primary line of defense in the event of a lightning strike to the aircraft.
1. Connect two ground straps (with at least 0.012 in
approximately equivalent to AWG 8) from the dedicated grounding lugs (the non-colored
pads) on the ECU to the dedicated airframe ground bus.
2. Connect two ground straps (with at least 0.012 in
approximately equivalent to AWG 8) from the dedicated grounding lugs (the non-colored
pads) on the Power Box to the dedicated airframe ground bus.
