Torque values for oil screen
Could someone please tell me the proper torque for the oil screen housing in my IO-520-FCL? Also the oil drain
plug? I can't get hold of my A&P until Monday but I want to change the oil tonight... Thanks! John Clonts Temple, Texas N7NZ |

Thanks! John Clonts Temple, Texas N7NZ John, Both of these items use a copper crush gasket for sealing. I am not aware of any "torque" value published for such items. Using *new* gaskets, turn the screen/plug in until gasket contact is made, then an additional 1/4 turn (45 degree rotation) should do it. As you are turning your wrench, you will feel the friction gradually increase, until proper compression is achieved, at which point the friction starts to rapidly increase. This is sometimes called the "calibrated elbow" approach, and is quite adequate for these types of gasket. As a side note, a quick drain plug greatly simplifies this procedure, if space permits. As far as the oil screen goes, most people safe-tie these, but is not necessary. Take a look at the next TCM factory new/overhauled engine you get a chance to see. Happy Flying!

Scott Skylane N92054 Thanks Scott, I ended up delaying so I can get the new gaskets. But I also found this: http://www.tcmlink.com/serviceBulletins/pdf/sb96-7B.pdf If I read it right it's about 16 ft-lbs for the oil sump drain, and 42 ft-lbs on the Oil filter screen...
