Lycoming O-360 oil suction screen torque
Hi,
I'm looking for the torque specification for the oil suction screen (the one near the bottom of the engine) for a Lycoming O-360. It's the A4A model. I'm planning on inspecting the suction screen on the next oil change. Thx! |

Lycoming O-360 oil suction screen torque
As I recall, that uses a crush-type copper asbestos gasket, so the plug
is trurned until the sealing surfaces just meet, then an additional angle depending on the thread pitch of the plug. 8-10 TPI gets 67 degrees of turn, 12-14 TPI gets 90 degrees, 16-20 TPI gets 135 degrees. This is for COPPER crush gaskets only, aluminum are different.

So if someone were to ask if the screen plug was cut you should answer it must have been broken. This goes for the oil filter safety wire to. Sometimes rules don't make sense, but rules are rules. What the hell are you talking about? As an owner I am allowed to safety the oil filter. If I look at it later and decide I don't like what I see I'll cut it out of there and replace it. |

FAR 43.14 says, under the "Preventive maintenance," section, that "Replacing defective safety wiring or cotter keys" is an acceptable preventive maintenance item. There is no restriction on how the safety wiring becomes defective, but my preferred method involves cutting the wire. JKG |

Lycoming O-360 oil suction screen torque
I can't cut safety wire unless I hold an A&P?
Gee! Lock me up. I've had to cut CSD disconnects on B727s twice in the last year. I had a Captain who had to cut the safety on a Pneumatic brake handle also.

I'm planning on inspecting the suction screen on the next oil change. Thx! I don't want to sound like a scrooge, but I would like to pass on some information about maintenance. Pilots and owners have to follow the same maintenance rules as A&P mechanics when performing preventive maintenance. In the case of changing the oil and checking the oil suction screen it is a good thing to do and should be done. However you will need the Lycoming 0-360 maintenance manual while you do the maintenance. The manual calls out a torque on the plug and if I recall it states to replace the copper casket. This will require you to have a calibrated torque wrench and make an engine/airframe record entry in accordance with part 43.9. To be on the safe side I would ask and A&P to check the work and have an A&P sign it off. As a pilot/owner we are allowed to repair broken safety wire, but are not allowed to cut it. So if someone were to ask if the screen plug was cut you should answer it must have been broken. This goes for the oil filter safety wire to. Sometimes rules don't make sense, but rules are rules.
