FUEL INJECTOR MAINTENANCE.
1. In general, little attention is required between injector overhauls. However, it is recommended that the
following items be checked during periodic inspection of the engine:
A. Check tightness and lock of all nuts and screws which fasten the injector to the engine, torquing all
nuts to 135-150 inch-pounds.
B. Seat the pal type locknuts and finger tighten them against the plain nuts. After this has been done
tighten the locknuts an additional 1/3 to 1/2 turn.
C. Check all fuel lines for tightness and evidence of leakage. A slight fuel stain adjacent to the air
bleed nozzles is not cause for concern.
D. Check throttle and mixture control rod ends and levers for tightness and lock.
E. Remove and clean the injector inlet strainer at the first 25 hours of operation and each 50 hour
inspection thereafter. Check the screen for distortion or openings in the strainer. Replace for either
of these conditions. Clean screen assembly in solvent and dry with compressed air. Damaged
strainer O-rings should be replaced. To install the screen assembly, place the gasket on the screen
assembly and install the assembly in the throttle body and tighten to 35-40 inch-pounds torque.
FUEL-AIR BLEED NOZZLE.
REMOVAL OF FUEL-AIR BLEED NOZZLE.
The nozzles must be carefully removed as they or the cylinders may be damaged.
1. Remove the lower engine cowl.
2. Disconnect the fuel line from the nozzle.
3. Carefully remove the nozzle, using the correct size deep socket.
4. Clean and inspect the nozzle as given in the next paragraph.
CLEANING AND INSPECTION OF FUEL-AIR BLEED NOZZLE.
1. Clean the nozzle with acetone or equivalent and blow out all foreign particles with compressed air in
the direction opposite that of fuel flow. Do not use wire or other hard objects to clean orifices. (Refer to latest
revision Lycoming Service Instruction No. 1275.)
2. Inspect the nozzle and cylinder threads for nicks, stripping or cross-threading.
3. Inspect for battered or rounded hexagons.
4. A test procedure for air bleed nozzles is described in latest revision Lycoming Service Instruction No.
1275.
