carusoam Posted October 29, 2019 Report Posted October 29, 2019 Oil screen or finger screen... will help with your search... Then safety wiring seems to be the next topic usually looked for with the fine experience you are going through...

Feel free to invent new words when doing it yourself. 2 Quote
Bolter Posted October 29, 2019 Report Posted October 29, 2019 I use two open wrenches with different head angles. One will fit, give just enough to turn so the other wrench will fit. Repeat until finger loose. Then get someone more skilled to restore the safety wire. :-) Quote
RobertGary1 Posted October 29, 2019 Report Posted October 29, 2019 There is no need to really touch it much. Get in there with a dyke and cut the safety wire. Then just a box end wrench to loose it (they're not tight at all). Then just do the 1 finger spin on it to pull it out. Its tight but so are lots of things. Getting the safety wire back on is the only hard part. I ended up twisting it by hand because I couldn't get the tool in there well enough to spin it. -Robert Quote
aaronk25 Posted October 30, 2019 Report Posted October 30, 2019 Does this need to be checked? Besides cutting filters? I want to say I have a great mechanic and he has never brought this up or logged it. Is it required and if so what does lycoming say?Sent from my iPhone using Tapatalk Pro Quote
carusoam Posted October 30, 2019 Report Posted October 30, 2019 Good question Aaron... The challenge... two filtering devices in series... 1) one has a coarse screen 2) The second has a fine paper mesh 3) The order these are in... is important.... If the screen is first then paper... large parts may be collecting over time, and not getting to the paper screen... If the paper is first, then the screen... the paper will collect everything, leaving the screen nice and clean... iirc... the screen comes first... 4) The filter probably doesn’t relieve the screen’s responsibilities... or it would get removed...no? 5) The screen’s ability to fill up with large chunks of carbon would cause some concern 6) Large chunks of carbon come from valve guides that want to be cleaned out... 7) When everything is operating properly, the screen has very little to show on it, even without a filter.... 8) Seems to be an annual requirement that has some flexibility... 9) I always opened mine up at annual... a couple of carbon pieces and flecks of aluminum over the years... 10) if large junks are collecting on the screen upstream... smaller bits will also be collecting downstream at an equally alarming rate... 11) When the cam comes apart... I was expecting to see the tsp full of parts to be in the screen... So... find out if the filter comes after the screen... PP thoughts only, not a mechanic... Best regards, -a- 1 Quote

It’s on the Mooney inspection check list. Clarence Quote

Best regards, -a- The screen is on the suction side of the pump and prevents big things from going through the pump and damaging it. The filter is on the output (pressure) side of the pump and prevents the smaller crap from going back into the bearings and passages. So, simply, screen->pump->filter->galleys->return 1 Quote
PT20J Posted October 30, 2019 Report Posted October 30, 2019 Don’t forget to use a new gasket (crush washer) when you reinstall it. Split side toward engine. 1 Quote
