Engine Installation
3-2.3.1. Engine Pre-oiling
CAUTION: If the engine oil cooler adapter is connected to an
aircraft mounted oil cooler, the oil cooler and hoses will contain
trapped air that oil servicing will not evacuate from the engine
lubrication system. Failure to purge the air from the oil cooler and
hoses prior to engine start will damage the engine.
1. Perform the “Engine Pre-Oiling” procedure according to the instructions in Section
5-2.9 of M-0, Standard Practice Maintenance Manual.
3-2.3.2. Fuel Purge and Leak Check
1. Connect a length of the appropriate size hose to the aircraft fuel supply using an AN
union fitting and secure the end of the hose in a properly grounded Type 1
flammable fluid container.
CAUTION: Ensure the ignition switch is in the OFF position and
clear the rotational arc of the propeller before proceeding.
2. Position the fuel selector valve to the ON position.
3. Allow a minimum of one quart (0.94 liter) of fuel to flow through a paper filter until
the fuel is free of contaminants.
4. Position the fuel selector valve to the OFF position.
5. Remove the hose and union installed in step 1 from the aircraft fuel supply.
6. Lubricate the male fitting threads with 50 weight aviation engine oil and connect the
aircraft fuel supply to the carburetor (or engine driven fuel pump, if equipped) inlet
fitting; torque the fuel hose “B” nut to Appendix B specifications.
7. Turn the aircraft fuel selector valve to the ON position.
8. Place the mixture control in FULL RICH.
9. Visually inspect all fuel lines, hoses, and fittings for evidence of fuel leakage.
Inspect the carburetor exterior, carburetor air inlet, and airbox for evidence of fuel
leakage.
10. If equipped, inspect the fuel priming system for leaks according to the aircraft
maintenance manual.
11. Place the mixture control to IDLE CUT-OFF.
12. Turn the aircraft fuel selector valve to the OFF position.
