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!

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.
